| Summary: | The catalytic conversion of a methane and ethylene mixture to gasoline range hydrocarbons has been studied over W/HZSM-5 catalyst. The effect of process variables such as temperature, % vol. of ethylene in the methane stream, and catalyst loading on the distribution of hydrocarbons was studied. The reaction was conducted in a fixed-bed quartz - micro reactor in the temperature range of of 300 to 500C using % vol. of ethylene in methane stream between 25 - 75 % and catalyst loading of 0.2-0.4 gram. The catalyst showed good catalytic performance yielding hydrocarbons consisting of gaseous products along with gasoline range liquid products. The mixed feed stream can be converted to higher hydrocarbons containing a high liquid gasoline product selectivity (>42%). Non-aromatics C5 – C10 hydrocarbons selectivity in the range of 12 - 53% was observed at the operating, conditions studied. Design of experiment was employed to determine the optimum conditions for maximum liquid hydrocarbon products. The distribution of the gasoline range hydrocarbons (C5-C10 non-aromatics and aromatics hydrocarbons) was also determined for the optimum conditions. |
