1,183,397. Mordenite zeolite. ESSO RESEARCH & ENG. CO. 28 Sept., 1967 [14 Oct., 19661, No. 44239/67. Heading B1E. [Also in Divisions C1 and C5] A mordenite catalyst having a SiO 2 /Al 2 O 3 molar ratio of at least 55 is prepared by treating a natural or synthetic mordenite with at least 1 N acid solution at a temperature not exceeding 220‹F for at least 1 hour. The catalyst may be impregnated with a platinum group metal, i.e. Pd, Pt, Ru, Rh, Os or Ir, preferably palladium or platinum, or may be used in a matrix of clay or an inorganic oxide gel. At least part of the hydrogen content may be replaced by metal cations having properties for the catalysing of hydrocarbon conversion reactions, these include Al, Be, Ca, Ce, Cr, Mg, Mn, Sr, Zn, Ag, Au, Cu, Fe, Ni, Sb and the rare earth metals either individually or, preferably, mixed. The mordenite has large pore diameters of 6.6A and smaller ones of 2.8A.
