Abstract: The production of light olefins from syngas is one of the hot topics to prepare important organic chemicals from non-oil resources. Technical progress in the process，including research on catalysts，reactors and process，was summarized. It is believed that highly active and selective catalysts are key to break the limit of ASF product distribution. Meanwhile，new reactors and novel processes development also contribute to the high yield of light olefins，CO2 emission reduction and acceleration of process commercialization via the combination of the process with other existing technologies. Compared with conventional steam cracking and methanol to olefins process，the direct production of lower olefins from syngas is economically competitive.
