China: Post Desulfurization of FCC Gasoline Clariant and Sinopec Sign Agreement on Fuel Upgrading Catalyst Technology

Editor: Alexander Stark

Clariant has signed two key agreements with Sinopec in Beijing. In the first agreement, Sinopec licenses its FCAS series of S-Zorb sorbent to Clariant. The second agreement is the FCC (Fluid Catalytic Cracking) Agency Agreement between Sinopec Catalyst Company (SCC) and Clariant Qatar W.L.L. stating that Clariant Qatar W.L.L. will be the representative for Sinopec’s FCC catalysts to oil refineries in Qatar.

Munich/Germany — FCC naphtha is the major contributor to the gasoline pool. However, it typically contains up to 2,000 ppm wt. sulfur. As the China V specification requires a sulfur concentration of below 10 ppm wt., sulfur removal is essential. Hydrodesulfurization, a method widely used to remove sulfur from naphtha, requires a considerable amount of hydrogen, and results in the loss of RON (research octane number). In contrast, the S-Zorb process uses catalysts to adsorb all sulfur species from FCC gasoline with high RON retention and high liquid yield. Moreover, the single step process requires no recycle streams, and consumes significantly less hydrogen. These factors have made S-Zorb a technology of choice in China for upgrading gasoline from China National IV (equivalent to Euro IV) to China National V (equivalent to Euro V) standards.

Since 2001, Clariant has partnered with Sinopec to supply next generation S-Zorb catalysts for producing low sulfur gasoline at more than 25 world-scale units in China and USA.

The FCAS cooperation agreement will allow Clariant to scale up the catalyst product portfolio for commercial production of low sulfur gasoline.

The company announced that the agreements were signed by the senior management on September 27, 2017.
