  • Catalyst for the pyrolysis of hydrocarbons
    Patent number: 4361502
    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.
    Type: Grant
    Filed: March 30, 1979
    Date of Patent: November 30, 1982
    Assignee: Institutul de Inginerie Tehnologica Si Proiectari Pentru Industria Chimica - IITPIC
    Inventors: Grigore Pop, Gheorghe Ivanus, Silvia Boteanu, Pavel Tomi, Ecaterina Pop
  • Catalytic process for preparing olefins by hydrocarbon pyrolysis
    Patent number: 4172816
    Abstract: A process and catalyst for the catalytic pyrolysis of hydrocarbon to olefins and diolefins at temperatures in the range 600.degree.-750.degree. C. and pressures of 0.1 to 20 atmospheres. The catalyst is a bifunctional synthetic modified mordenite zeolite of the formula (yH.multidot.zM.multidot.uNa) O.multidot.Al.sub.2 O.sub.3 .multidot.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.
