With the continuous development of oil refining industry, the Fcc catalytic cracking of petroleum deep processing becomes important
Section. In the refining industry plays a decisive role. The FCC process is appropriate, the purpose of heavy oil products
Gasoline, diesel oil and gas is. Due to the high conversion, product quality is good, nearly half a century, the FCC
Art technology and production scale have very big development. In order to meet the requirements of environmental protection and increasingly strict market of propylene
Hydrocarbon (especially propylene), the growing demand in catalytic cracking technology and further development and improvement. push
The refining industry has become a cracking of core technologies and petrochemical enterprise economic benefits of main pillar.
As the core of the refinery process device, catalytic cracking faces more challenges. Constantly strictly
The environmental protection request, mainly is the upgrade of gasoline specification requirements and sulfur content in olefins and flue gas emissions limits
: Demand for products, such as the ratio of diesel market changes and the increasing number of demand, the so-called wood
Oil tendency. All of the existing FCC catalytic cracking unit and the further development of the formation of the big rush
Strike. In addition to using new effectively lower the FCC gasoline and diesel outside the sulfur. Consider each
The cost of technical problems.
The FCC industry in China since the 1960's, device number and production capacity constantly high,
According to not complete count, existing catalytic cracking unit nearly 100 sets of production, processing capacity of more than 5,000 million t/a,
After the United States, ranking second in the world. In recent years, residue catalytic cracking had great progress, not only widen the sources of the raw materials, and FCC gasoline and diesel increased production in China, accelerate the process of heavy oil yields
