Why do I love chemical so much?

Traditional chemical industry: Introduce the difference and connection between chemical industry and oil, coal, natural gas, biomass industry! 1. Let's start with oil, which in principle is a sunset industry. Oil is a complex mixture of many carbon substances, and then all kinds of substances are separated from it! Some of these substances are used as raw materials in various industries, mainly physical changes, rectification! Some carbon number of substances need to be further decomposed into small molecules, and then used in all walks of life, this is often said catalytic cracking, this is chemical change! 2. Talk about coal, coal is mainly a carbon mixture, so the goal of coal chemical industry is to obtain carbon number of substances, used in various industries, natural gas or shale gas is the same, collectively referred to as carbon chemical industry, chemical change! However, 1.2 has a very important physical change process, that is, substance purification, generally distillation! 3. When these non-renewable energy sources are used up, it is biomass (including the current treatment of domestic waste), and then a series of chemical processes and physical processes to obtain various chemical products in life! Therefore, from the perspective of traditional chemical industry, unless people want to return to primitive society or there is no human, it is impossible to leave chemical industry! 

New chemical industry: new energy such as hydrogen energy, including hydrogen preparation hydrogen liquefaction hydrogen fuel cells; Research and development of new materials, such as military nylon, hydrogen storage containers, accelerants, materials for various purposes, etc.; The new chemical industry is a multi-disciplinary work, we often say that the chemical material inside the biochemical ring material! New chemical industry is definitely the key to the economic transformation of the motherland, we still need to work hard! As for fine chemical and low temperature separation, there are some chemical separations that are not well understood, such as the separation of isomers, I will not introduce them, because the physical and chemical knowledge mastered in the traditional chemical industry can also be used in this! Why is the chemical industry bad? The first point is heavy capital, the value of people is worthless in front of capital! One of the best things to do in this line is consulting, one is technical services, one is a university teacher to do marketing, personal entrepreneurship is not called entrepreneurship, called successful entrepreneurs! Heavy capital also leads to a long cycle of technological change processes in the industry. The second point is that we are in this stage of China, are the production of mass products, the technology used is either very mature technology or not much real own technology (once in the chemical design institute, understand one or two), but it has trained so many talents (Nanjing University chemical chemistry can not find a job), very embarrassing! Third, there are too many talents, but using you and him are the same, so it is not the price of cabbage!

What should chemical people do? 

1. Engineering field, in terms of the breadth, chemical industry is a part of the process industry, the process industry needs too many disciplines, and chemical industry related, first is chemical reaction or separation theory, computational fluid mechanics or computational mass transfer, then chemical automation or chemical control, and then chemical equipment! In depth, it is also the above things! Breadth to give a lot of choices, professional is dead people are alive, you do not have to change careers or learn other professional to do things! If you are good at reaction theory, you can do reactor development, computational mass transfer if you are good at it, you can do fluid mechanics, chemical control or automation. If you are good at it, you can do automation or computer or systems engineering (systems engineering is a big subject, you can do statistics, you can do operations and you can do optimization)! Breadth gives you space, depth depends on you! You are not the same as others, you are valuable! Use it if you can! It's up to you! Of course, people who are not good at math, this road is basically impassable, and very painful! 

2. Academically, this requires the courage to break the boat and the will to persist! Why do I separate engineering from academics? I think chemical engineering is all about theory and mathematics, while academics are experiments, because these people who experiment are all future academicians! The experiments I'm talking about here are those water paper experiments! Instead of verifying the experiment, this level is the bad money to drive out the good money, there are many good engineering R & D personnel, but by these water papers to the pit, the result is that everyone together water papers! I look at the problem from a practical point of view, these years have trained too many academician candidates, the motherland needs some research projects within 5 or 10 years, the industry needs transformation, not too much research 50 or 100 years after the talent (this is also the biggest joke in China, 50 or 100 years after the major research should be sent in English), Is it necessary to introduce from abroad, then what is the meaning of their own training talents? In my opinion, the way out of the chemical industry is in the chemical industry itself, which needs pragmatism!
