Abstract
A catalyst, for the catalytic pyrolysis of hydrocarbons to olefins and diolefins at temperatures in the range of 600.degree.-750.degree. C. and pressures of 0.1 to 20 atmospheres, is a bifunctional synthetic modified mordenite zeolite of the formula (yH.zM.uNa) O.Al.sub.2 O.sub.3.SiO.sub.2 wherein M is Cu, Ag or Co/2 and u+y+z approach or equal 2. Good yields of ethylene and propylene are obtained from hydrocarbon feedstocks having boiling points up to 550.degree. C.
Claims5
