Catalytic conversion of oxygenated compounds to low molecular weight olefins. Progress report, January 1-July 31, 1979. [Methanol from synthesis gas from coal gasification]

Description: An attractive route for producing ethylene and propylene from coal is to gasify the coal to produce synthesis gas, convert the synthesis gas to methanol, and then convert methanol to the olefins. During this report period the reactions of methanol over chabazite ion exchanged with rare earth chlorides have been studied at reciprocal liquid hourly space velocities of 1.5 to 15, at temperatures of 259, 271, 304, 352, and 427/sup 0/C, and at pressure 2.7 atm. At 259 and 271/sup 0/C the principle p… 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

Novel reactor configuration for synthesis gas conversion to alcohols

Description: Research continued on the design of a chemical reactor for synthesis gas conversion. During the second quarter our objective was to continue with Task 2 and start on Task 3. Task 2 involved standardization and automation of GC analysis protocols. Task 3, as stated in the work breakdown schedule, was the modification and automation of the trickle bed reactor and performing the initial factorial design experiments. We have decided to modify this task by expanding it to incorporate determination o… more

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, 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

Oxygen electrode reaction in molten carbonate fuel cells. Final report, September 15, 1987--September 14, 1990

Description: Molten carbonate fuel cell system is a leading candidate for the utility power generation because of its high efficiency for fuel to AC power conversion, capability for an internal reforming, and a very low environmental impact. However, the performance of the molten carbonate fuel cell is limited by the oxygen reduction reaction and the cell life time is limited by the stability of the cathode material. An elucidation of oxygen reduction reaction in molten alkali carbonate is essential because… more
