Clariant International Ltd said that it has signed two key agreements with Sinopec, China’s largest petroleum and chemical company.
The first of these is the FCAS Series Sorbent Agreement in which Sinopec has agreed to license its FCAS series of S-Zorb sorbent to Clariant. The cooperation agreement will allow Clariant to scale up the catalyst product portfolio for commercial production of low sulfur gasoline.
The second is the fluid catalytic cracking (FCC) agency agreement between Sinopec Catalyst Company (SCC) and Clariant Qatar WLL stating that Clariant Qatar WLL will be the representative for Sinopec’s FCC catalysts to oil refineries in Qatar.
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).
