Combined process and industrial application, residue hydrodesulfurization-residue catalytic cracking combined process residue hydrodesulfurization tail oil as residue catalytic cracking feed, improved the composition of catalytic cracking feedstock (increased hydrogen-carbon ratio, removal Impurities have greatly increased the depth of processing, increased the light oil yield to a maximum, reduced the sulfur content of catalytic gasoline, and improved the economic efficiency of refineries. Maoming Petrochemical Company used this process to process a mixture of Arabian light crude oil and Arab heavy crude oil.
Catalytic cracking combined process of wax oil hydrodesulfurization and wax oil This combination process is mainly used for the refinery processing of sulfur-containing crude oil or high-sulfur crude oil. The catalytic cracking feed after the hydrodesulfurization of the wax oil can make the sulfur content in the catalytic cracked flue gas. In line with environmental protection requirements, the sulfur content of gasoline meets the requirements of the standard. Dalian Western Pacific Petrochemical Company adopted this process to process Iranian light crude oil.
The use of heavy oil catalytic cracking gasoline MCSP deodorization technology has been successful in the reform of raw liquid and liquid extraction oxidation refining systems. The transformation investment is small, the construction time is short, and the processing capacity is greatly improved. The actual production index exceeds the design value. The heavy oil catalytic cracking gasoline MCSP deodorization device has the characteristics of long catalyst bed operation cycle, simple operation, stable quality of refined gasoline products, good refining effect, high qualified rate of refined oil products in the PHD test, and no alkali residue discharge. The second-generation active agent has a high activity and a small addition amount, which has a cleaning effect on the deodorizing bed and prolongs the operation cycle of the catalyst bed. The use of heavy oil catalytic cracking gasoline MCSP deodorization technology, greatly reducing the alkali consumption, reducing costs, but also reduces environmental pollution, with a certain degree of economic and social benefits.
