The equilibrium conversion is thermodynamically limited. Because of direct contact between carbon and steam significant amounts of carbon oxide and NOx are produced. We have demonstrated in the laboratory a new way to make ethylene via ethane dehydrogenation using a dense hydrogen transport membrane (HTM) to drive the unfavorable equilibrium conversion. Preliminary laboratory experiments have shown the new approach can afford ethylene yields significantly above the thermodynamic equilibrium limit, at high ethane conversion, while completely eliminating production of green house gases. This new approach affords a much simpler product slate and lower the cost. |  | This paper is available to CTSI members in PDF© format. | | ISBN: | 1-4200-8502-0 |
