Abstract
Synthesis gas (a mixture of hydrogen gas and carbon monoxide) is converted to hydrocarbons by flowing the gas first over iron-containing Fischer-Tropsch catalyst and then over a zeolite. The Fischer-Tropsch catalyst contains relatively little nitrogen as a result of its preparation by continuous precipitation at a pH ranging from about 6.6 to 6.9 and a temperature ranging from about 80.degree. to about 100.degree. C.
