Clariant and Sinopec sign catalyst agreements

Published by

Senior management officials of Clariant and Sinopec signed two key agreements in Beijing. One agreement was a series sorbent agreement, in which Sinopec has licensed its FCAS series of S-ZorbTM sorbent to Clariant. The second was for fluid catalytic cracking (FCC) cooperation, under which Clariant Qatar W.L.L. will be the representative for Sinopec’s FCC catalysts to oil refineries.

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

FCC naphtha is the major contributor to the gasoline pool. However, it typically contains up to 2000 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 research octane number (RON). 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.

Clariant has partnered with SINOPEC to supply next generation catalysts for producing low sulfur gasoline at more than 25 world-scale units in China and USA since 2001. In all cases, the technology and catalysts have demonstrated their superior performance in clean energy production and emission control.
