Many basic chemicals that are used as feedstock for the chemical and petrochemical industries, such as acetylene and ethylene, are derived from the refining of petroleum. However, in order to decrease domestic dependence on imported petroleum and to increase utilization of the domestic natural gas supply, there is considerable incentive for the selective production of basic chemicals from natural gas. This project will develop a process for the selective conversion of methane to alkynes or dienes, through a novel intermediate, for use as chemical and petrochemical feedstocks. The technical and economic feasibility of the proposed CH4 conversion process was evaluated during Phase I activities by using a combination of methods. Detailed thermodynamic equilibrium calculations identified viable experimental conditions; experimental data identified potentially optimal intermediates and temperatures of operation; and a preliminary process engineering and economic model identified important process variables. Significant reductions in energy consumption and waste generation per unit production of acetylene were indicated (compared to existing technologies). Phase II will optimize the experimental conditions and reactor configuration for CH4 conversion to acetylene. Technical issues related to reactor and process development will be addressed.
Commercial Applications and Other Benefits as described by the awardee: The technology should provide a selective and cost-competitive method for natural gas conversion to acetylene.
