Technologies for reducing olefins in fuel: The non-hydrogenation reforming technology for straight-run gasoline developed by the Petroleum Chemical Science Research Institute uses a certain proportion of straight-run gasoline and residual C4 hydrocarbons as raw materials. Through a series of complex reactions such as C4 olefin polymerization and dehydrocyclization, selective cracking of straight-run gasoline, isomerization, oligomerization, and cyclodehydrogenation, it is possible to increase the octane number of straight-run gasoline. This process is characterized by a simple procedure, low investment, mild operating conditions, and a low dry gas yield. The gasoline produced by this technology has good octane sensitivity, making it highly valuable for blending.
In my opinion, the best approach is to start at the source; hydrogenation of the raw materials is the most effective method.
The production of clean fuels relies mainly on product hydrogenation, as well as technologies for reducing the olefins content in gasoline. I think the catalytic MIP technology is quite effective in reducing olefins, and it is widely used these days.
Should the hydrocarbon recombination process carried out by Jin Weihui Company also be considered as one?
The series of clean fuel production technologies developed by the Petroleum and Chemical Science Research Institute, including the RSDS and RIDOS technologies for reducing sulfur content in FCC gasoline, are advanced technologies capable of meeting China’s National 3 and National 4 standards. The RTS technology for reducing sulfur in diesel is also an advanced technology that enables the production of ULSD (Ultra-Low Sulfur Diesel). Currently, Sinopec is purchasing the S-Zorb adsorption desulfurization technology from ConocoPhillips; this technology will serve as the key solution for Sinopec’s refineries to achieve a gasoline sulfur content of 10 ppm in the future.
