The toluene disproportionation catalyst manufactured according to the technology developed by SPRI had been successfully put on stream at the first attempt at the Belorussian Naftan Company on September 14,2007. The reaction temperature using the said catalyst was lower by 50℃ as compared to the overseas catalyst that was applied by the Naftan Company previously, indicating to the excellent performance of the said catalyst. This successful commissioning of the process unit has laid a good foundation for expansion of SPRI＇s global market share.展开更多

The toluene disproportionation unit, which was put on stream with success at the first attempt, ran smoothly and performed a continuous examination calibration for 72 hours in January 2006. At a space velocity of 4.0 h^-1, the average toluene conversion was higher than 30 %, with the para-isomer selectivity exceeding 92 % and the B/X ratio less than 1.4 （mol/mol）.展开更多
