Abstract
A catalytic process for the deoxygenation of an organic substrate, such as a biomass or bio-oil, is described. The catalytic process is conducted in the presence of a gaseous mixture containing both hydrogen and nitrogen. The presence of nitrogen in the gaseous mixture gives rise inter-aliato increased catalytic activity and/or increased selectivity for aromatic reaction products.
Claims16
A catalytic process for reducing the oxygen content of an organic substrate, the process comprising the steps of:
- a) providing a mixture comprising:
- i. the organic substrate, wherein the organic substrate is one or more organic compounds selected from the group consisting of p-cresol, m-cresol, eugenol, guaiacol, 4-ethyl-guaiacol, 3-propyl-guaiacol, syringol, 4-methyl-syringol, 4-allyl-syringol and 1,3,5-trimethoxybenzene;
- and
- ii. a catalyst;
- b) contacting the mixture of step a) with a gaseous mixture comprising hydrogen gas and nitrogen gas to reduce the oxygen content of the organic substrate,
- wherein the volume ratio of hydrogen gas to nitrogen gas in step b) is 1:0.5 to 1:20.
