The present invention relates to a process for producing alcohols by hydrogenation of C13 aldehydes. The process according to the invention is performed in two consecutive hydrogenation stages, wherein the first hydrogenation stage employs an activated metal catalyst based on a nickel metal foam and the second stage employs a supported catalyst containing a catalytically active component from the group consisting of nickel, copper, chromium and mixtures thereof.

A process for producing ethylene glycol and/or propylene glycol and/or glycerol in a continuous manner from a feed comprising a carbohydrate source in an aqueous liquid and hydrogen may include a reactor producing a liquid product flow out of the reactor and an off-gas, a downstream purification section comprising one or more distillation and/or evaporation units for subjecting the liquid product flow out of the reactor to one or more distillation and/or evaporation steps, and a hydrogen production section. The hydrogen production section may include a steam methane reformer (SMR) unit, a water gas shift reactor (WGS) unit, and a pressure swing adsorption (PSA) unit.

A method for producing a hydrogen-enriched gas, the method including: (A) generating a mixed gas containing hydrogen and oxygen in a reactor that decomposes water into hydrogen and oxygen using sunlight in the presence of a photocatalyst; (B) collecting the mixed gas in a storage tank; (C) supplying the mixed gas in the storage tank to a gas separation device that includes a membrane having an ability to separate hydrogen and oxygen; and (D) separating a hydrogen-enriched gas from the mixed gas in the gas separation device.
