▎ 摘　　要

NOVELTY - A modified copper-zinc-alumina (CZA) catalyst comprises copper, zinc, one or more elements (E1) chosen from cobalt, iron, or nickel, aluminum, oxygen, optionally, one or more elements (E2) chosen from group (V), (VI), (VII), (VIII), (IX), (X), and (XI) metal (e.g., manganese, silver, niobium, zirconium, molybdenum, ruthenium, or palladium), and optionally, one or more group (IA) metals. The modified CZA catalyst comprises 1-40 wt.%, preferably 35-40 wt.% element (E1) with respect to copper, zinc, element (E1), element (E2) and group (IA) metal (in total). USE - Modified copper-zinc-alumina catalyst used in catalytic composition for reducing carbon dioxide in feed mixture for preparing liquid product mixture comprising methanol, ethanol, n-propanol and formaldehyde (all claimed). Can also be used for hydrogenation of carbon dioxide to methanol. ADVANTAGE - The catalyst has high selectivity, produces ethanol from carbonaceous feedstocks at a higher rate, and inhibits the formation of gaseous byproducts during operation, e.g. methane, to further enable effective recycle of unreacted gases during product gas recycle in a multipass gas to liquids reactor for methanol production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) catalytic composition, which comprises the catalyst, and an additional support; (2) preparation of catalyst, which involves preparing the catalyst by coprecipitation, wet impregnation, or ball milling; and (3) reducing carbon dioxide, which involves contacting the catalyst or the catalytic composition with a feed mixture comprising carbon dioxide and a reductant gas at a reduction temperature and a reduction pressure to obtain a liquid product mixture.
