Description

technical field [0001] The invention relates to the technical field of energy conservation and environmental protection, in particular to a low-carbon olefin catalyst prepared from synthesis gas and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy and the increasing demand for low-carbon olefins, the production of low-carbon olefins from raw materials such as naphtha and light diesel oil through cracking methods is far from meeting market demand and will face a serious shortage. In recent years, with the decreasing of petroleum resources, domestic and foreign researches mainly focus on non-petroleum routes, that is, using coal and natural gas resources to directly or indirectly produce low-carbon olefins. my country is relatively rich in coal and natural gas resources, and the technology for preparing synthesis gas from coal and natural gas is relatively mature. Therefore, we propose a low-carbon olefin c...
