Catalytic Conversion of Oxygenated Compounds to Low Molecular Weight Olefins. Progress Report, March 1, 1980-August 31, 1980

摘要

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 exp 0 C, 800 psig, and 6000 h exp -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.
