The hydro-desulfurization technology brings the sulfur content of gasoline within the global limit. The gasoline turned out by SPC recently contains only 52 ppm sulfur, about a quarter of the 200 ppm national fuel limit.

With an increasing public awareness in environment protection, China has set a new specification to regulate the quality of motor fuels, in which, gasoline sulfur is limited not to exceed 200 ppm this year. The limitation complies with that of the requirement of class 2 gasoline called by the "Worldwide Fuels Charter".

The technique applied by SPC aims at satisfying this requirement.

The raw gasoline contains sulfur at the range of 800-1200 ppm. After being treated with the RSDS technique, the finished gasoline sulfur lowered down to 200 ppm and less.

SPC-made fuels will be more competitive on domestic and global market with the application of this technique, an official from the company said.

SPC put of about 700, 000 tons of gasoline every year now.
