摘要:
在水热条件下,以正丁胺为模板剂,在高岭土微球中合成了晶粒直径约0.2-1μm的ZSM-5沸石粉体。采用X射线衍射、扫描电镜、N2吸附脱附方法对合成样品进行了表征。催化裂化选择性评价结果表明:在基础重油裂化催化剂LHO-1中,采用添加10%(质量分数,下同)所合成的高岭土微球(含27%ZSM-5)作为助剂,丙烯产率由2.96%提高到4.78%,焦炭和干气选择性不变;同时汽油质量明显提高,汽油芳烃减少近10%(体积分数),汽油辛烷值增加1.8。

Small crystal size zeolite ZSM-5, with a size of 0.2-1 @@m, was synthesized on kaolin microspheres under hydrothermal crystallization conditions using n-butylamine as template. The zeolite products were characterized by X-ray diffraction, scanning electron microscopy, and adsorption and desorption isotherm plot. Compared with base catalyst LHO-1 for heary oil cracking, when 10% (in mass, the same below) kaolin microspheres containing 27% ZSM-5 synthesized in this study was added as an additive, the reaction results in a small-scale fluid-bed reactor show that the propylene yield increases from 2.96% to 4.78% (in mass), and dry gas selectivity is not changed. The gasoline quality improves significantly with aromatics reduce about 10% (in volume) and the octane number increases by 1.8.
