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 process for manufacturing a Fluid Catalytic Cracking catalyst additive composition with a novel binder. The steps involve mixing an alumina source with water to make a slurry; adding to the alumina slurry an amount of P2O5 source; the slurry is then stirred and reacted under controlled temperature and time conditions to form an aluminum phosphate binder; adding to the aluminum phosphate binder a zeolite, an amount of silica binder and an amount of clay; and spray-drying the slurry to form catalyst additive particles. The catalyst additive composition comprises a about 35 wt % to about 65 wt % zeolite; about 0 wt % to about 10 wt % silica; about 15 wt % to about 50 wt % clay and an aluminum phosphate binder comprising about 2.5 wt % to 5 wt % amorphous or pseudo-boehmite alumina and about 7 wt % to 15 wt % phosphoric acid.

The present invention provides processes for selectively producing ethanol from syngas. In some variations, the process comprises converting biomass-derived syngas to dimethyl ether, carbonylating the dimethyl ether to methyl acetate, hydrogenating the methyl acetate to methanol and ethanol, and recovering the ethanol product. The methanol is preferably recycled by converting to hydrogen and carbon monoxide for introduction back into the process at distinct points. In certain variations of this invention, fresh syngas feed is introduced downstream of the first unit operation in the sequence. High yields of ethanol from biomass can be achieved according to the disclosed processes.

Abstract

Improved methods of introducing promoters to catalysts are described. The present invention provides a convenient method of uniformly distributing a catalyst promoter, to provide for intimate contact between the promoter and the active catalyst sites. This intimate contact can enhance the activity and/or product selectivity of the promoted catalyst. In some embodiments, the method includes reacting an alkali metal with an alcohol in a non-aqueous medium, contacting the resulting solution with a starting catalyst, and depositing the alkali metal onto the starting catalyst to form an alkali-promoted catalyst.

Abstract

Methods are provided for producing alkylbenzenes, such as propylbenzene, from aromatics, such as toluene, and alkenes, such as ethylene. Such methods comprise combining the toluene with about 100 ppm to about 350 ppm water and alkali metal catalyst, activating the catalyst at about 180° C. to about 220° C., adding the ethylene and conducting the synthesis reaction at about 130° C. to about 150° C.

Abstract

The invention herein provides methods of activating a catalyst composition. These methods include annealing a catalyst with an inert gas, under effective conditions, and then contacting the annealed catalyst with syngas to produce an activated catalyst. These steps can also be reversed. The activated catalysts can be employed to convert syngas into products, such as alcohols, with improved selectivities and yields.
