Discussion on Reform of Chemical Technology Teaching

There is no way out.

Chemical engineering is a major specialty course for chemical engineering and technology. The reform of this course is imperative.

The chemical process is based on chemical products. In addition to studying their scientificity and practicality, in the long-term teaching practice, they have summarized the features of comprehensive complexity-related systematicity and development. Therefore, in the teaching process, the heuristic discussion method of the South is adopted, with the emphasis on methodology, the connection of theory with practice, and improvement of students and pioneering spirit.

1.3 The characteristics of arts Chemical process mainly introduces the conditions of production process of chemical products. Equipment structure performance and its optimization organization and design calculations Due to the large scope of chemical industry and the wide variety of products, it is objectively difficult to organize with a wide coverage. But if you are good at inducting Zhou Zhongqing, the East China University of Science and Technology, School of Petrochemicals. 59 to find its common law, these questions can be resolved through a lot of practice, summed up the chemical process has the following characteristics: Chemical process is a comprehensive reflection of basic courses professional basic courses and professional courses. The students are required to be good at applying the basic knowledge and basic theories they have learned, and to solve the problem of how to organize the actual production of technological production so as to learn and learn deeply.

The chemical processing process is very complicated, so the chemical process has the characteristics of complexity. In the process, the focus is on discussing the contents of thermodynamics and chemical reaction engineering. The relevant theories will be thoroughly explained in conjunction with the actual conditions of the factory. The students will have a deeper understanding and discuss in depth the process of influencing the reaction according to the laws of thermodynamics and dynamics. The various factors to determine the better process conditions to produce qualified products.

In order to achieve industrial production, in addition to mastering the knowledge of chemistry and chemical engineering, it is also necessary to have relevant knowledge of the mechanical and electrical equipment, civil engineering, safety, waste disposal, management, and market information. In this way, the craftsman can put forward the conditions for the equipment structure and performance mechanical principles and operating electrical circuit and operating equipment and automatic control and other aspects to meet the process production requirements. Therefore, it is necessary to strengthen the horizontal relationship with related disciplines. Often cited examples to analyze. To reflect the dominant role and position of the craftsman in the factory or design or research institute.

1.4 systematically learn to fully analyze the process of the product is a complete system, there is internal contact, should use the method of system engineering analysis, a comprehensive analysis of the process, put forward the principle of the organization process, let students design their own organizational process, this It has a lot of advantages over the technology of rote memorization and can open up ideas.

1.5 Developmental ability to cultivate innovation Chemical production With the development of science and technology, new technologies, new technologies, new equipment and new materials are emerging.

Changes in the structure of raw materials The development of new catalysts has brought new changes to the chemical industry. This requires teachers to keep abreast of research trends and trends at home and abroad, constantly provide new information for students, point out new directions for development, and increase interest. Foster innovative capabilities.

Students in other colleges and universities, through years of university life and study, are mainly learning and mastering really good skills and knowledge. The key lies in the cultivation of competence. Modern college students must have the ability to conduct scientific research. Ability to analyze and judge talents. Ability to reach talents. Ability of social interactions, etc., can be called ground-breaking 2.1 Ability to develop theory and practice. Ability to develop, only by strengthening the basic knowledge of basic theory Skills education can be obtained, so that students have a solid foundation and skilled basic skills.

These basic trainings are not enough to rely solely on the teaching of book knowledge. Each teaching link must be strengthened, and theoretical knowledge should be effectively linked with practical questions. Constantly the courage to practice, continuous exploration, and continuous review of experience in order to deepen the understanding of the theory sublimation.

The effective way to develop competence lies in the combination of theory with practice and learning methods. Chemical process not only needs to understand the process, but more importantly, how to design and analyze the process. For example, in the chapter on thermal cracking of hydrocarbons, according to the laws of thermodynamic analysis and dynamics, the organization principles of pyrolysis process should be proposed. 1 How to meet the special requirements of high temperature and low hydrocarbon partial pressure and short residence time for cracking, and 2 How to quench the pyrolysis products? Up to 100 or less, 3 energy must be comprehensively used to improve economic efficiency; 4 Strictly control the span temperature; 5 In order to increase the ethylene yield, it is necessary to solve the problem of the dissolution of ethylene in water or fuel oil; 6 Water must be used in a closed loop to reduce waste. deal with. According to these organizational principles, students can design a variety of cracking processes to develop their own comprehensive analytical skills.

2.2 Objectives To clearly grasp the direction of development New technological advances have promoted the development of chemical engineering and process expertise. Entering the new century, chemical engineering and technology majors are developing in both directions to microcosmic aspects, gradually forming molecular chemical engineering; and from the macroscopic direction, new systemic chemical engineering is being formed. These research trends and development trends at home and abroad should be appropriately added to teaching, indicating the direction of development and laying the groundwork for students' future work.

3. Teaching reforms According to the characteristics of chemical engineering, we must update educational perspectives, improve teaching methods, and constantly improve teaching quality. 3.1 Selected Contents Highlights Key chemical technologies are rich in content and variety. However, due to the limited hours, it is imperative that we carefully select the content and carefully teach it.

Select a typical process, the main point must be clear and highlight the difficulties to make it clear. By contrast, by analogy.

3.2 The teaching method is more flexible. In the teaching process, the system and flexibility are combined. The use of a heuristic system to switch to page 25 process specialist course system compared to the following characteristics of a reasonable theoretical course theoretically strong and the professional training objectives are not much related to the curriculum is no longer open, such as chemical thermodynamic reaction engineering and separation engineering . Courses related to this major are based on practicality and are subject to adjustments and mergers in content, such as the deletion of basic courses in chemical equipment including engineering mechanics and material mechanics calculations and equipment selection; the integration of basic mechanical knowledge into chemical engineering In the course, the addition of electronic technology was merged with electrotechnics as a basic course for electrical and electronics; general physics only retained thermal and electromagnetic two-part content.

Strengthen and add practical courses to strengthen the course of Chemical Engineering, and increase its curriculum design to two times: Application of English Writing and Computer Application and Computer Network Courses to improve overall quality.

Establish chemical equipment corrosion and protection Chemical safety and environmental protection chemical computer simulation to improve the basic knowledge and skills of chemical production.

Emphasis on practical skills, reform of practical courses teaching professional courses related to the opening of the experimental project, do not do the verification theory of the experiment, do less nature experiments, and more to do the preparation of synthetic testing experiments. Students are trained in the use of instruments, operating skills and experimental methods to improve the ability to observe and resolve questions.

Traditional production internships and graduation internships are changed to practical training courses, and are shared by the company’s engineering and technical staff and school teachers. After a long period of time, the standardized training of on-site operation will enable students to obtain the true skills of post operation skills troubleshooting and production management not only to achieve the skill level of middle-level skilled workers, but also to apply the learned knowledge to propose measures for technological transformation.

Graduation is divided into graduation training and process calculations.

The selection of process calculations is the production of graduate training products.

In the graduation training, determine the process flow with control points, calculate the main parameters of the typical equipment, and draw the process flow on page 60. The use of self-study methods for class discussion, mutual exchanges; layout operations, Write a special paper; use video video teaching, the image meets the real workshop, field teaching and other methods.

3.3 Emphasis on Methodology Education changes the model of imparting knowledge in the past and places emphasis on methodological education, so that students can passively accept knowledge and become active participants and think actively. For example, it describes how to obtain knowledge, how to, and how to read the literature, how to analyze the system, and summarize and sort out the methods.

3.4 Combining scientific research, broadening horizons, strengthening technical and economic analysis, and adapting to the needs of the market economy We have developed the Unit 51 type catalyst, which has made the method of ethane ingestion a new life for ethylene, known abroad as bio-ethylene. Combine this scientific research achievement into the teaching process. For example, when explaining the pyrolysis of ethylene to petroleum, the preparation method of bio-ethylene was introduced. By comparison of the technical and economic analysis of petroleum ethylene and bio-ethylene, the production costs are almost the same. Teaching in this way not only enlarges the knowledge surface, but also enables the students to have an economic brain, enhancing their technical and economic analysis capabilities and adapting to the needs of the market economy.
