HYDROCARBON CONVERSION CATALYST AND PROCESS FOR SELECTIVELY MAKING MIDDLE DISTILLATES |
摘要 |
<p>HYDROCARBON CONVERSION CATALYST AND PROCESS FOR SELECTIVELY MAKING MIDDLE DISTILLATES A hydrocarbon conversion catalyst useful for converting hydrocarbon feeds to midbarrel products is prepared by extruding a mixture of a porous, inorganic refractory oxide component and a crystalline aluminosilicate zeolite having cracking activity to form extrudates which are broken into particles normally ranging in length between 1/16 and 1/2 inch. The extruded particles are then calcined in the presence of added steam at a water vapor partial pressure greater than about 2.0 p.s.i.a., preferably greater than about 5.0 p.s.i.a. The calcination step is carried out in the presence of sufficient added steam for a sufficient amount of time at a sufficient temperature to convert the crystalline aluminosilicate zeolite in the extrudates into an ultrahydrophobic zeolite having a unit cell size between about 24.20 and about 24.45 Angstroms and a sorptive capacity for water vapor less than about 5 weight percent of the zeolite at 25.degree. C. and a p/p.degree. value of 0.10.</p> |
