摘要： Catalytically active amorphous silicas are prepared by dehydrating a silica hydrogel or precipitate prepared from an acidified aqueous silicate solution containing an amine of pK.sub.a above 10 or a cation containing either a nitrogen or phosphorus atom bonded to four carbon atoms. The resultant amorphous silica is catalytically active for, among other chemical reactions, the isomerization of ortho-xylene and the cracking of hydrocarbons.

摘要： A process for producing a thermally shock calcined aluminosilicate zeolite comprising (A) precalcining an aluminosilicate zeolite at a relatively low temperature, (B) very rapidly increasing the temperature of the aluminosilicate zeolite to a relatively high temperature for a short period of time, and (C) rapidly cooling the aluminosilicate zeolite. The resulting zeolite is catalytically active for hydrocarbon conversion reactions and is particularly selective for the production of para-xylene from a reaction mix of toluene and a methylating agent.

摘要： A silica polymorph suitable for use in preparing an aromatic alkylation or isomerization catalyst is prepared by hydrothermally crystallizing said silica polymorph from a silicate solution containing an organic agent, in combination with a base solution, and an acid solution. Crystallization is effected utilizing high shear mixing followed by an unagitated period during the crystallization of said silica polymorph.
