What field does the catalytic gasoline adsorption desulfurization device belong to?

Mainly used for catalytic desulfurization of gasoline. The process technology of S-Zorb catalytic gasoline adsorption desulfurization unit can produce low-sulfur gasoline with low octane number loss below 10ppm. Generally, thiophene sulfur which is difficult to remove is hydrogenated and easy to remove. This technology has a history of about 10 years since the development of adsorbents. 1998, COP began to develop S-Zorb adsorbent, and at the same time began to study S-Zorb process technology. 1999, the adsorbent was industrialized and a pilot-scale experimental device was built. In April of 200 1 year, the industrial demonstration unit of Borg Refinery started. In 2007, China Petrochemical acquired S-Zorb process technology as a whole, and completely owned the patented technology.
