Catalytic conversion of oxygenated compounds to low molecular weight olefins. Annual report for January 1--December 31, 1978

Description: The conversion of methanol or synthesis gas is an attractive route for producing ethylene and propylene from coal. Utilizing a chabazite ion exchanged with ammonium and rare earth chlorides, methanol is converted to ethylene, propylene, and propane with carbon yields of 70 to 90% at reaction temperatures of 360 to 450/sup 0/C and pressures from 1 to 18 atmospheres. Carbon disulfide in the feed at concentrations less than 2000 ppm increases the operating time between regenerations from four hour… more

Catalytic conversion of oxygenated compounds to low molecular weight olefins. Progress report, January 1--July 15, 1978

Description: The conversion of methanol or synthesis gas is an attractive route for producing ethylene and propylene from coal. Utilizing a chabazite ion exchanged with ammonium and rare earth chlorides, methanol is converted to ethylene and propylene with carbon yields of 70 to 90% at reaction temperatures of 375 to 425/sup 0/C and pressures to 100 psi. Carbon disulfide in the feed at concentrations less than 200 ppM increases the operating time between regenerations from four hours to twenty hours. At car… more

Catalytic conversion of oxygenated compounds to low molecular weight olefins. Progress report, March 1, 1980-August 31, 1980

Description: A possible route for producing low molecular weight olefins is to convert synthesis gas to methanol followed by conversion of methanol to olefins in a one-step process. During this report period the reaction apparatus suitable for reaction pressure of 500 to 1000 psig was constructed. A preliminary trial run was performed for the reaction of synthesis gas over an intimate mixture of methanol synthesis catalyst and Zeolon-500 (mixture of chabasite and erionite). The reaction temperature, pressur… more
