摘要： The present invention relates generally to processes for producing aldehydes wherein an olefinic compound, carbon monoxide, and hydrogen are reacted in the presence of a solubilized rhodium-phosphorous complex. In one embodiment, the process comprises (a) receiving a vaporized aldehyde product stream downstream from a hydroformylation reactor, the vaporized aldehyde product stream comprising aldehydes, phosphorous ligand, and aldehyde condensation by-products; (b) contacting the vaporized aldehyde product stream with a partial condenser so as to condense the phosphorous ligand and the by-products, wherein up to 10 weight percent of the vaporized stream is condensed; (c) removing the condensed phosphorous ligand and the condensed by-products from the liquid condensation stream using a refining column; and (d) further processing the vaporized aldehydes from the separate refining column.

摘要： A method for producing A hydrogen gas from formic acid, characterized in that at least one heterogeneous catalyst is used to transform the formic acid into hydrogen gas. The at least one heterogeneous catalyst contains heterogenized ruthenium. According to a first aspect of the invention, the at least one heterogeneous catalyst contains at least one hydrophilic phosphine ligand which is m-TPPTS (meta-trisulfonated triphenylphosphine). The at least one heterogeneous catalyst is preferably obtained by mixing an aqueous solution of RuCl3 with hydrophilic phosphine, firstly activated by carrying out a homogeneous reaction with formic acid and by adding at least one solid structure.
