    Abstract: Presented is a process for the preparation of zeolitic material through condensed gel crystallizations. The present disclosure describes methods for improved preparation of zeolites by preparing an aqueous precursor mixture; removing at least 5 wt% of the total water from the aqueous precursor solution to create a solution with greater solids content; crystallizing the solution of step (b) to create a zeolite product. The resulting zeolites can show improved mesoporosity without any post-treatment to create mesoporosity. This effect is particularly prominent in ZSM-5 zeolites, for example.

    Abstract: Provided is a Fluid Catalytic Cracking catalyst additive composition and method of making the same. The catalyst additive composition comprises zeolite about 35 wt % to about 80 wt %, preferably about 40 wt% to about 70 wt%; silica about 0 wt% to about 10 wt%, preferably about 2 wt% to about 10 wt%; about 10.5 wt% to 20 wt % alumina and about 7 wt% to 20 wt% P 2 O 5 , preferably about 11 wt% to about 18 wt %, and the balance clay which can fall between 0 and 50 wt%. The alumina is typically derived from more than one source, such as at least an amorphous or small crystallite size pseudo-boehmite alumina and then either a either a large crystallite size alumina or other reactive alumina.
