改性ZSM-5分子筛经过喷雾干燥得到100～ 200目的催化剂粉,在内径为32 mm流化床反应器内进行甲醇制汽油(MTG)的催化性能评价实验.考察了质量空速、反应温度、反应压力等工艺条件对MTG的影响,分析了甲醇转化率、汽油收率、产物分布和产物的变化规律.结果表明,提高压力有利于增加汽油收率;加入镧系元素催化剂在反应温度为380℃,反应压力为0.5 MPa、空速4.6h-1的条件下,甲醇转化率为100％,汽油收率可达30％左右.“,”The 100-200 mesh catalyst powder is prepared by modified ZSM-5 molecular sieve through the spraydrying method.The catalytic performance of the prepared catalyst for methanol to gasoline is evaluated in a bench-scale fluidized bed reactor with an inner diameter of 32 mm.The influences of mass hour space velocity (MHSV),reaction temperature,reaction pressure and other conditions on methanol to gasoline are investigated.The changing rules of methanol conversion,yield of gasoline,product distribution and transformation are analyzed.The results show that the increase of reaction pressure is helpful to improve gasoline yield.With the addition of lanthanide elements into catalyst and at temperature of 380℃,pressure of O.5 MPa,and WHSV of 4.6 h-1,the conversion rate of methanol and the yield of gasoline reach 100％ and 30％,respectively.
