Claims38
A process for converting hydrocarbons comprising contacting a hydrocarbonaceous feed at hydrocarbon converting conditions with a catalyst comprising a zeolite having an average pore size greater than about 6 Angstroms and having the X-ray diffraction lines of Table I.
A process for converting lower alcohols and other oxygenated hydrocarbons comprising contacting said lower alcohol or other oxygenated hydrocarbon with a catalyst comprising a zeolite having an average pore size greater than about 6 Angstroms and having the X-ray diffraction lines of Table I under conditions to produce liquid products.
In a process for the reduction of oxides of nitrogen contained in a gas stream in the presence of oxygen wherein said process comprises contacting the gas stream with a zeolite, the improvement comprising using as the zeolite a zeolite having a mole ratio of an oxide of a first tetravalent element to an oxide of a second trivalent or tetravalent element which is different from said first tetravalent element, said mole ratio being greater than about 20 and having the X-ray diffraction lines of Table I.
