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, pressure and space velocity were 400/sup 0/C, 800 psig, and 6000 h/sup -1/ (STP), respectively. The total carbon monoxide conversions were 15 to 24%. The major products were carbon dioxide and paraffins of C/sub 1/ to C/sub 4/. Deactivation of the catalyst occurred after 10 hours. X-ray diffraction patterns of the catalyst shows that crystal structure changed during the reaction, and the catalyst exhibited low crystallinity compared to synthetic erionite.
