PROCESS FOR PRODUCTION OF FORMIC ACID AND ACETIC ACID BY ABSORBING COSub2/Sub VIA PHOTOCATALYTIC REDUCTION, IMPROVED CATALYST AND APPARATUS

摘要

The present invention relates to a process for converting CO2 to short chain organic acids, which comprises the steps of: a) dissolution of silver containing fulvate chlatrate komplex catalyst in water to produce a catalyst solution; b) charging the catalyst solution into a pressure reactor; c) introducing a CO2 source into the reactor; d) exposing the reactor space with sunlight or artificial light, or electromagnetic wave while measuring the concentration of the produced organic acids; e) repeating the steps of c) and d) until the concentration of the produced organic acids reaches 2 to 5 % by weight in the reaction mixture; f) if the concentration of the produced organic acids reaches 2-5% by weight, collecting the aqueous solution from the, filtering and concentrating the same. The present invention also relates to a silver-containing fulvate-clathrate complex catalyst.
