CONVERSION OF GREENHOUSE GASES BY DRY REFORMING
20170129777 · 2017-05-11 ·

A method for conversion of greenhouse gases comprises: introducing a flow of a dehumidified gaseous source of carbon dioxide into a reaction vessel; introducing a flow of a dehumidified gaseous source of methane into the reaction vessel; and irradiating catalytic material in the reaction vessel with microwave energy. The irradiated catalytic material is heated and catalyzes an endothermic reaction of carbon dioxide and methane that produces hydrogen and carbon monoxide. At least a portion of heat required to maintain a temperature within the reaction vessel is supplied by the microwave energy. A mixture that includes carbon monoxide and hydrogen can undergo catalyzed reactions producing multiple-carbon reaction products in a lower-temperature portion of the reaction vessel.

Furan-2,5-dicarboxylic acid purge process

Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.

Conversion of alcohols to alkyl esters and carboxylic acids using heterogeneous palladium-based catalysts

Disclosed are methods for synthesizing an ester or a carboxylic acid from an organic alcohol. To form the ester one reacts, in the presence of oxygen gas, the alcohol with methanol or ethanol. This reaction occurs in the presence of a catalyst comprising palladium and a co-catalyst comprising bismuth, tellurium, lead, cerium, titanium, zinc and/or niobium (most preferably at least bismuth and tellurium). Alternatively that catalyst can be used to generate an acid from that alcohol, when water is also added to the reaction mix.
