NOVELTY - A carbon-containing catalyst comprises a metal oxide, a molecular sieve, and carbon in a weight ratio of 1:(0.25-5):(0.002-0.3), preferably 1:(0.3-3):(0.01-0.18). USE - Carbon-containing catalyst is used for producing low-carbon olefin (claimed). ADVANTAGE - The carbon-containing catalyst can be prepared by a simple method, has excellent strength after formation, and provides high conversion and selectivity in production of low-carbon olefin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of low-carbon olefin, which involves reacting a raw material containing carbon monoxide and hydrogen by contacting with the catalyst.
