Oil remover and its production

Abstract

An oil-removing agent used in high-pressure gas environment is proportionally prepared from silicate, C-contained substance and co-oxidant through pulverizing, adding water for wetting, mixing, shaping, baking, and calcining at 600-800 deg.C for 10-50 hr.

Description

technical field [0001] The invention relates to a degreasing agent and a preparation method thereof, in particular to a degreasing agent used in a high-pressure gas environment. Background technique [0002] In chemical production, gas raw materials often participate in the reaction. When the raw materials contain oily impurities, it often affects chemical production or product quality. For example, in various chemical processes that use catalysts after compressors, the compressor pressurizes the raw gas , Compressors often use engine oil to prevent wear and tear. The industrial raw material gas pressurized by the compressor contains a small amount of engine oil. In chemical production, catalysts are often used to improve production efficiency. The catalyst is a solid substance with good porosity, and the compressor discharges gas The engine oil in the gas is adsorbed by the catalyst, which reduces the catalytic activity of the catalyst and reduces the production efficiency....

[0002] In chemical production, gas raw materials often participate in the reaction. When the raw materials contain oily impurities, it often affects chemical production or product quality. For example, in various chemical processes that use catalysts behind the compressor, the compressor pressurizes the raw gas , Compressors often use engine oil to prevent wear and tear. The industrial raw material gas pressurized by the compressor contains a small amount of engine oil. In chemical production, catalysts are often used to improve production efficiency. The catalyst is a solid substance with good porosity, and the compressor discharges gas The engine oil in the gas is adsorbed by the catalyst, which reduces the catalytic activity of the catalyst and reduces the production efficiency. Therefore, a deoiling agent with good deoiling effect and low cost is needed to remove the engine oil in the raw gas, for example, the transformation of the ammonia plant Reaction, using all-low temperature conversion catalyst, due to the interference of oil in the exhaust gas of the compressor, the activity of the conversion catalyst is quickly reduced, the production temperature rises, the steam consumption increases, the production efficiency decreases, and the production cost increases. The above production situation, domestic has existed for many years
