The development of catalysts in China

The first catalyst production workshop in China is the catalyst Department of yongliqian plant. It was renamed as catalyst plant of Nanjing Chemical Industry Company in 1959. In 1950, AI type ammonia synthesis catalyst, C-2 type carbon monoxide high temperature conversion catalyst and VI vanadium catalyst for sulfur dioxide oxidation were produced. After that, various catalysts needed for ammonia industry were gradually prepared. In 1980s, China began to produce supported nickel catalysts for natural gas and light oil steam conversion. By 1984, more than 40 units had been produced catalysts for sulfuric acid, nitric acid and ammonia synthesis.

In order to develop fuel chemical industry, in the early 1950s, the third petroleum plant began to produce molybdenum sulfide clay, tungsten sulfide activated carbon, tungsten sulfide clay, pure tungsten sulfide and molybdenum sulfide catalyst for shale oil hydrogenation. The co catalyst for feto synthesis was started in the sixth petroleum plant, and the phosphate diatomite catalyst was produced in 1960. In the early 1960s, China developed abundant oil resources and began to develop the industrial production of oil refining catalyst. At that time, the petroleum catalytic cracking catalyst was first produced in Lanzhou Refinery, and the small spherical aluminum silicon catalyst plant was built and put into operation in 1964. In 1970s, China began to produce rare earth-x molecular sieves and rare earth Y-type molecular sieves. In the late 1970s, the co glued silica aluminum carrier rare earth Y zeolite was produced in the catalyst plant of Changling refinery. Later, the high reactor ratio and wear-resistant semi synthetic rare earth Y zeolite were started in the catalyst plant of Qilu Petrochemical Company. Since the 1960s, China began to develop reforming catalyst, and the third petroleum plant began to produce platinum catalyst in the mid-1960s. In the 1970s, bimetallic platinum rhenium catalyst and polymetallic reforming catalyst were successively produced. In the aspect of hydrofining, the No.3 oil plant began to produce molybdenum cobalt and molybdenum nickel reforming pre hydrogenation catalyst in 1960s. In the 1970s, the low pressure pre hydrogenation catalyst of Mo Co Ni was produced, and the hydrofoil catalyst with trilobite was produced in the 1980s.

In order to develop organic chemical industry, iron catalysts for dehydrogenation of ethylbenzene, mercury chloride / activated carbon catalyst for acetylene hydrogenation to vinyl chloride, vanadium oxide catalyst for naphthalene oxidation to phthalic anhydride in fluidized bed, and skeleton nickel catalyst for hydrogenation have been manufactured from the end of 1950s to early 1960s. In the mid-1960s, in order to meet the needs of petrochemical industry in China, the new production of catalysts increased rapidly. By the 1980s, a variety of selective hydrogenation catalysts for refined olefins had been produced, and microsphere oxide catalysts for propylene ammoniation oxidation, supported metal catalysts for ethylene and acetic acid oxidation to vinyl acetate, high efficiency olefin polymerization catalysts and control workers had been produced Honeycomb catalyst for industrial waste gas, etc.

Catalyst is widely used in all walks of life. In the future, no matter in the scientific research of catalyst, the development and utilization of clean energy, environmental protection and economic benefits improvement, as well as the management and protection of human living environment, there will be great development prospects. In short, the survival and development of human beings can not be separated from the catalyst and its development.
