1. BackgroundEthylene glycol（EG）is the raw material for the production of PET polyester, which is used in textile and packaging，and China is a big user of PET polyester. China's ethylene glycol market has a huge gap. In recent years, the annual import of ethylene glycol is 8 ~ 10 million tons, and there is a rising trend.At present, ethylene glycol production method is mainly the oil route: ethylene as raw materials, through ethylene oxide ethylene glycol production. The method of preparing syngas from coal and preparing ethylene glycol from syngas is very suitable for the situation of more coal and less oil in China, and has a great development prospect. 2.

1. BackgroundOxalamide, also known as oxalic acid diamide, CAS login number: 471-46-5. Its molecular weight is 88.07, nitrogen content is 31.8%, slightly soluble in water, insoluble in ethanol and ethyl ether, does not absorb moisture, stable nature, easy to store, can be decomposed into ammonia and carbonic acid, is a good and efficient slow-release fertilizer. Oxamide compared with traditional fast effective nitrogen fertilizers (such as urea) in China: it‘s not volatile, insoluble in water, not easy to lose, the nitrogen utilization rate is high, and it can reduce economic losses and water pollution. Oxalamide, as an efficient slow-release fertilizer, will have a huge market and broad prospects in China. 2. Flow Sheet 3.&#...

Higher mixed alcohols（higher alcohols） can be obtained from syngas under catalysis. Higher alcohols are not only excellent fuel additives, which increase the octane number and oxygen content of fuel, are but also important raw materials, which are produced methanol, ethanol, propanol and butanol, etc. after separation. It is difficult to select appropriate catalyst in order to achieve high selectivity of higher alcohols, and separate mixed alcohols. The researchers of our company combined many active metals, decorated the surface of catalyst and developed a high performance catalyst, which has high selectivity of C2+ alcohols, more than 50%. In the meantime, a new separation technology was also developed, which can reduce the cost on separation of mixed alcohols.

1.BackgroundEthanol（alcohol）, is widely applied in many fields, such as food (from fermentation), medicine, chemical raw materials and vehicle fuels, etc. With the promotion of ethanol fuel in China, the demand for fuel ethanol is expected to about 13.57 million tons. But, the output of fuel ethanol is only 2.58 million tons in 2016. It is indicated that ethanol fuel has vast prospects for development.Ethanol from syngas is in line with China's national conditions of more coal and less oil, as well which is avoided competing with people for food, has a lot of room for development. The main technologies of ethanol from syngas are as follows: (1) indirect method. First, syngas is produced to acetic acid or acetate. Acetic acid or acetate is conversed to ethanol under catalytic hydrogenat...

1. BackgroundThe characteristics of China's energy reserves are 'rich in coal, short of oil, short of gas'. Coal has a high position in the national energy strategy. China's coal resources are mainly medium and low grade coal. These coals are highly volatile and suitable for pyrolysis poly-generation. It can improve the quality and grade utilization of coal, improve the utilization efficiency of coal and increase the economic benefits. 2. Technological processThe coal pyrolysis poly-generation technology is based on low quality coal as raw material, through pyrolysis, produce gas, coal tar, semi-coke, heat, electricity, chemical products, ash and slag comprehensive utilization, building materials.Coal gas from coal pyrolysis can be m...

1. BackgroundCoal tar is a liquid product of coal in the process of dry distillation and gasification. Coal tar contains a variety of complex compounds, rich in phenols, organic amines, and aromatic hydrocarbons. Compared with petroleum, coal tar contains more oxygen and nitrogen atoms, high content of polycyclic aromatic hydrocarbons, low content of heavy metals, high content of mechanical impurities, odor, toxic, easy to produce environmental pollution.According to different production methods, the following types of tar can be obtained:High temperature coal tar (900 ~ 1000℃);Medium temperature coal tar (700 ~ 900℃);Medium-low temperature coal tar (600 ~ 800℃);Low temperature coal tar (450 ~ 650℃). 2.
