| titleOfInvention | Catalyst for directly preparing olefin from synthesis gas, preparation method and use method |
| abstract | A catalyst for preparing olefin directly from synthetic gas is composed of the first metal component, the second metal component and basic assistant. The preparation method comprises the following steps: firstly, preparing a salt of a first metal component and a salt of a second metal component into an aqueous solution, mixing, dropwise adding an alkaline auxiliary agent precursor solution, and obtaining the catalyst by controlling the temperature, the pH value and the stirring rate, and performing suction filtration, drying, roasting and other steps. The using method comprises the following steps: by H 2 Or the obtained catalyst is reduced by the synthesis gas, mixed gas with the H2/CO molar ratio of 1:1-8:1 is introduced, and the temperature and the volume space velocity are respectively 0.1-5MPa (absolute pressure), 250-450 ℃ and 500-10000H ‑1 The olefin synthesis reaction is carried out. The catalyst prepared by the method can convert the synthesis gas into hydrocarbon products with high olefin content in one step, and has the characteristics of high raw material conversion rate, high olefin yield, low cost and easy amplification. |
