1400797 Alkylation catalyst UNIVERSAL OIL PRODUCTS CO 9 Nov 1972 [10 Nov 1971] 51738/72 Addition to 1334928 Heading B1E [Also in Division C5] An alkylation catalyst comprises a zeolite impregnated with one or more of Cu, Ag, Au and Zr, present as metals, wherein the zeolite has a silica to alumina mole ratio of at least 40:1 and has been prepared by acid-extraction of alumina from a mordenite of silica to alumina mole ratio of 12:1 to 30:1 by use of on at least normal aqueous solution of hydrochloric, sulphuric or nitric acids, the mordenite itself having been formed by maintaining at 25-300‹ C a reaction mixture comprising 1 molar part of Al 2 O 3 , from 12 to 30 molar parts of SiO 2 as cogel for the alumina, from 1.5 to 2.5 molar parts of Na 2 O and water present in the reaction mixture in an amount of from 60 to 200 moles per mole of Na 2 O. Suitably, the catalyst contains 0.01- 10% wt of the metal and the zeolite has a silica to alumina mole ratio of from 50:1 to 100:1.
