Abstract
This invention provides a phosphide catalyst for syngas conversion and the production method and use thereof, more specifically, to a catalyst for converting a syngas raw material into oxygenates, comprising one or more metallic Fe, Co, Ni and their phosphides, the production method of the catalyst and its use in the reaction of converting a syngas raw material into hydrocarbons and oxygenates. According to the invention, a catalyst for converting H2/CO into hydrocarbons and oxygenates, supported by SiO2 or Al2O3 and comprising one or more metallic Fe, Co, Ni and their phosphides under certain reaction temperatures and pressures is provided. The catalysts are consisted of two parts of an active component and a support. The active component is a mixture consisted of one or more of metallic Fe, Co, Ni and their phosphides. The support is selected from SiO2 or Al2O3. In a fix-bed or slurry bed reactor, H2/CO can be converted into oxygenates having two carbons or more and hydrocarbons with high activity and high selectivity, under certain reaction temperatures and pressures and the action of the catalyst in the invention.
