Claims
- 1. The process for the conversion of a hydrocarbon gas stream into products including liquid hydrocarbons comprising the steps of:
- first, catalytically reacting the hydrocarbon gas in a first reaction zone in the presence of water and sufficient carbon dioxide to produce hydrogen and carbon monoxide product in a ratio of hydrogen to carbon monoxide of from about 0.5 to about 2.0 to 1 and then removing carbon dioxide from the hydrogen and carbon monoxide produced in this step and recycling at least a portion of this carbon dioxide back to the first reaction zone;
- second, catalytically reacting the hydrogen and carbon monoxide having a reduced carbon dioxide content in a second reaction zone in the presence of a slurry containing an alkali promoted iron-based catalyst under conditions favoring the formation of carbon dioxide, light hydrocarbon gases, and normally liquid hydrocarbons containing at least five carbon atoms, and hydrocarbon waxes, and then separating the liquid hydrocarbon products from the gaseous products; and
- third, reacting the gaseous products in a third reaction zone in the presence of a slurry containing an alkali promoted iron-based catalyst to produce additional liquid hydrocarbon product.
- 2. The process of claim 1 wherein the ratio of carbon from the hydrocarbon gases first reacted to carbon dioxide is one part of carbon from hydrocarbon gas to up to two parts of carbon dioxide.
- 3. The process of claim 2 wherein the ratio of carbon from hydrocarbon gas to carbon dioxide and water is one part of carbon from the hydrocarbon gas to four parts of carbon dioxide and water.
