Process for the Production of Light Olefins from Synthesis Gas

摘要

A new process for light-olefins production is disclosed. The process comprises the step of contacting syngas with a iron-based catalyst at a temperature in the range from 250° C. to 350° C. and at a pressure in the range from 10 bar to 40 bar. By so doing a production of light olefins with a selectivity of at least 80% is obtained.

1. A process for the production of C2-C4 olefins comprising the step of contacting syngas with a iron-based catalyst at a temperature in the range from 250° C. to 350° C. and at a pressure in the range from 10 bar to 40 bar, wherein said iron-based catalyst includes nano-sized Fe particles as active component which are dispersed on a support or matrix, said nano-sized Fe particles being Fe nano-particles, Fe alloy nano-particles, nano-particles having an iron or iron alloy core and an iron-oxide shell or mixtures thereof.
