Abstract

Provided is a process for producing an aldehyde from an alkylene. The process includes (a) photocatalytically dehydrogenating at least one alkane to obtain a mixture comprising at least one olefin and hydrogen, (b) adding carbon dioxide and hydrogen to the mixture, and (c) hydroformylating the olefin to at least one aldehyde. The process also includes converting carbon dioxide and hydrogen into water and carbon monoxide prior to the hydroformylating. In addition, the conversion of carbon dioxide and hydrogen into water and carbon monoxide is performed by a reverse water gas shift reaction.
