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 H/CO into hydrocarbons and oxygenates, supported by SiOor AlOand 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 SiOor AlO. In a fix-bed or slurry bed reactor, H/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.

Phosphide catalyst for syngas conversion and the production method and use thereof

The invention provides an activated carbon supported cobalt based catalyst for directly converting of synthesis gas to mixed linear alpha-alcohols and paraffins, comprising cobalt, an activated carbon carrier, a metal promoter which is at least one selected from the group consisting of a zirconium component, a lanthanum component, a cerium component, a chromium component, a vanadium component, a titanium component, a manganese component, a rhenium component, a potassium component, a ruthenium component, a magnesium component and a mixture thereof, wherein the cobalt and the promoter are deposited on the activated carbon carrier or substantially uniformly dispersed therein, and the metal promoter is present in the form of a metal, an oxide or a combination thereof.

Activated carbon supported cobalt based catalyst for directly converting of synthesis gas to mixed linear alpha-alcohols and paraffins

The invention provide a process for producing directly mixed linear alpha-alcohols having 1 to 18 carbon atoms from synthesis gas comprising hydrogen and carbon monoxide, comprising the step of reacting hydrogen and carbon monoxide over a catalyst to produce mixed linear alpha-alcohols having 1 to 18 carbon atoms and hydrocarbons having 1 to 25 carbon atoms through Fischer-Tropsch process in one step in a reactor, wherein: the mole ratio of hydrogen to carbon monoxide is within the range of 1 to 3; the catalyst is an activated carbon supported cobalt based catalyst; the reactor is a fixed bed reactor, a slurry reactor or a fluid reactor; the reaction is carried out under specific conditions.
