1. The starting point of coal chemical industry is gasification of coal. What is gasification of coal? It involves subjecting coal to thermochemical treatment to convert it into the useful components CO and H2; in this process, the energy conversion efficiency is around 70–80%. A large amount of wastewater is generated at the same time. 2. During the synthesis phase, when CO and H2 are combined, a large amount of heat is generated as well as a significant quantity of steam. What is the purpose of this? For civilian use, the energy efficiency during operation is 50–70%. 3. What happened to the chemical fertilizers? Fertilizers applied in farmlands to promote crop growth have an efficiency of less than 50%. In other words, coal is transformed into food, and fossil fuels are turned into biological energy; the food we eat is, in effect, coal. 4. Synthesis of methanol – Converting synthetic gasoline and gas into these liquid products requires a high degree of compression, even when catalysts are used; this is a principle that remains valid. Converting 4–5 tons of coal into 1 ton of coal is not only economically advantageous despite the technical challenges, but the energy utilization efficiency is extremely low, at around 30% in such cases. It’s just to adapt to people’s current usage habits regarding liquid fuels, and it consumes a significant amount of energy. 5. Drive a car. What do you do with a car? To increase mobility, earn money quickly, and improve living standards. The energy efficiency of gasoline in cars is unknown, but what’s the use of that? In short, production has accelerated, and life is filled with a large number of unnecessary products. Everyone is making products in exchange for others’ products. Will people’s standard of living improve like that? ? ? The next round of product upgrades is about to begin. The food we eat is derived from energy, the houses we live in are made using energy-derived materials (paint, PVC, Pb, etc.), steel is produced through processes that utilize energy, and cars are driven by energy. With such endless product upgrades, energy must be consumed; according to the principle of energy balance, a large amount of coal energy is converted from underground into the atmosphere. Temperatures are rising, so countries have begun to control CO2 emissions. A new industry has been put into operation, involving the use of a large amount of energy to compress gaseous CO2 underground, in the hope that this will prevent temperatures from rising Really? No, this is a lie. It is true that CO2, as a greenhouse gas, slows down the Earth’s ability to dissipate heat, but the greenhouse effect in the atmosphere is not that simple. As large amounts of coal, oil, and natural gas underground continue to be converted into heat in the atmosphere through various means (due to extremely low efficiency, a great deal of heat is released into the atmosphere), temperatures will continue to rise. What should I do? 1. Countries should regulate the development of new industries; innovation should not be pursued in certain fields. All industries consume energy. So IT doesn’t consume energy either? Since the advent of computers, electricity consumption in each household has increased by about 30%. 2. Slow down the pace of life, reduce movement speed, and maintain a certain standard of living. To what extent should artistic standards be set? 3. Stop focusing on research and development; all energy consumption stems from the production of new industries and new products. In ancient China, there were very few people engaged in research, and people’s lifestyles were more in line with natural principles. In ancient times, only a few doctors and astronomers were famous. The most common celebrities are artists and poets. Everyone, don’t worry about issues like climate change. Once a piece of scientific research is initiated, many new studies are needed to address its flaws. Originally, people used firewood for heating, but a scientist discovered that coal could be used as fuel; so they began to extract coal. Later, another scientist came up with a new method – mechanized coal extraction. People thought this was great, and so mechanization was adopted. People had nothing to do, so scientists started working on coal chemical engineering. What do you use the coal you dig for? I turn it into gas and deliver it to thousands of households; then people stop using coal and start using gas instead. It was delivered in cans, and later scientists began working on pipeline gas. Later on, when mining for coal, it was found that there was no more coal left. What to do? They began to explore bioenergy (using firewood). After going through all that, everyone started burning wood again (bioenergy). It seems that scientific research can’t be carried out. It’s the same in other industries as well. It’s all a cycle. 4. Have more children and a variety of livestock. This is all labor power, as well as biological energy. It can pull rickshaws and large carriages. There will be no oil in the near future. Rickshaws have replaced cars; there isn’t enough manpower. There aren’t enough livestock either
