Catalyst China's development process

The first catalyst production workshop in my country was the Catalyst Department of Yongli Mineral Plant, which was renamed Nanjing Chemical Industry Corporation Catalyst Factory in 1959. In 1950, it began to produce AI-type synthetic ammonia catalyst, C-2-type carbon monoxide high-temperature shift catalyst and VI-type vanadium catalyst for sulfur dioxide oxidation, and then gradually completed the production of various catalysts required by the synthetic ammonia industry. In the 1980s, China began to produce supported nickel catalysts for steam reforming of natural gas and light oil. By 1984, more than 40 units had 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 catalysts for shale oil hydrogenation. Petroleum No. 6 Plant began to produce cobalt-based catalysts for Fischer-Tropsch synthesis, and since 1960 produced phosphoric acid-diatomite catalysts for stacking. In the early 1960s, China developed abundant petroleum resources and began to develop the industrial production of petroleum refining catalysts. At that time, the petroleum catalytic cracking catalyst was first produced in Lanzhou Refinery, and in 1964, the small spherical silicon-alumina catalyst plant was completed and put into operation. In the 1970s, China began to produce rare earth-X molecular sieves and rare earth-Y molecular sieves. In the late 1970s, the catalyst plant of Changling Oil Refinery began to produce co-colloidal silica-alumina carrier rare earth-Y-type molecular sieves. Later, the catalyst plant of Qilu Petrochemical Company began to produce semi-synthetic rare-earth-Y-type molecular sieves with high heap ratio and wear resistance. Since the 1960s, China has begun to develop reforming catalysts. In the mid-1960s, the Third Petroleum Plant began to produce platinum catalysts. In the 1970s, bimetallic platinum-rhenium catalysts and multi-metal reforming catalysts were successively produced. In terms of hydrorefining, the No. 3 Petroleum Plant began to produce molybdenum-cobalt and molybdenum-nickel reforming pre-hydrogenation catalysts in the 1960s. In the 1970s, the production of molybdenum-cobalt-nickel low-pressure pre-hydrogenation catalysts began, and in the 1980s, the production of trilobe-shaped hydrotreating catalysts began.

In order to develop the organic chemical industry, from the late 1950s to the early 1960s, it began to manufacture iron-based catalysts for ethylbenzene dehydrogenation, mercuric chloride/activated carbon catalysts for the production of vinyl chloride from acetylene, and oxidation of naphthalene in fluidized beds to produce phthalic anhydride. Vanadium catalysts, and framework nickel catalysts for hydrogenation, etc. In the mid-1960s, in order to meet the needs of the development of China's petrochemical industry, the variety of newly produced catalysts increased rapidly. By the 1980s, a variety of selective hydrogenation catalysts for refined olefins had been produced, and the production of microspherical oxides for the ammoxidation of propylene began. Catalysts, supported metal catalysts for the oxidation of ethylene and acetic acid to vinyl acetate, high-efficiency olefin polymerization catalysts, and honeycomb catalysts for industrial waste gas treatment.

Catalysts are widely used in all walks of life around the world. In the future, there will be great development prospects in the scientific and theoretical research of catalysts, the development and utilization of clean energy, environmental protection and improvement of economic benefits, and the management and protection of human living environment. In short, human survival and development, food, clothing, housing and transportation are inseparable from catalysts and their development.
