Abstract

The invention relates to a porous ceramic supported iron-based Fischer-Tropsch catalyst, a preparation method and a using method of the catalyst, and mainly solves the problem of low activity and selectivity of the catalysts at a low temperature for preparing olefin by using synthesis gas. In the method, a technical scheme of using a synthesis gas to prepare the low-carbon olefin catalyst is adopted to solve the problem well, wherein the catalyst comprises the following components in percentage by weight: (1) 20-80% of Fe contained active components, and (2) 20-80% of large-surface porous ceramic carriers. The catalyst can be used in industrial application of preparing low-carbon olefin by synthesis gas.

Description

technical field [0001] The invention relates to a porous ceramic loaded iron-based Fischer-Tropsch catalyst and a use method thereof. 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 g...
