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
