Abstract

The invention relates to a reaction method for preparing low carbon olefins from CO hydrogenation. The problem that the selectivity of a catalyst in the process of preparing olefins from synthesis gasis low is mainly solved. The reaction method for preparing the low carbon olefins from CO hydrogenation includes the step that synthesis gas and a catalyst are subjected to a contact reaction to generate the low carbon olefins, wherein the catalyst is prepared from, by weight, 30%-70% of Mo-containing active components and 30%-70% of carriers in the technical scheme; the problem is well solved, and the reaction method can be used for industrial application of preparing the low carbon olefins from the synthesis gas.

Description

technical field [0001] The invention relates to a reaction method for preparing low-carbon olefins by CO hydrogenation. Background technique [0002] Low-carbon olefins (olefins with carbon atoms ≤ 4) represented by ethylene and propylene are the basic raw materials of the chemical industry. At present, the main raw materials of low-carbon olefins in the world are petroleum hydrocarbons, of which naphtha accounts for the majority, and there are Alkanes, hydrogenated diesel oil, some heavy oil, etc. At home and abroad, natural gas or light petroleum fractions are mostly used as raw materials, and low-carbon olefins are produced by steam cracking in ethylene complexes. Steam cracking is a large energy-consuming device in petrochemical industry, and it completely depends on non-renewable petroleum resources. With the increasing shortage of oil resources, it is urgent to find alternative resources. Therefore, the research work of producing olefins from natural gas instead of ...
