The resulting mix-ture is then subjected to a temperature at which the iso-alpha-acid (or tetrahydro-iso-alpha-acid) containing reaction medium is sufficiently low in viscosity to allow easy mixing with the heterogeneous ruthenium containing catalyst and held under a hydrogen containing atmosphere (either pure hydrogen gas or mixed with an inert gas) for a reaction tune sufficient to effect high conver-sion of the iso-alpha-acid (or tetrahydro-iso-alpha-acid) reactant into the hexahydro-iso-alpha-acid product. The molar ratio of iso-alpha-acid or tetrahydro-iso-alpha-acid to ruthenium varies between 1:1 and 2000:1. After the hydrogenation process, the hetero-geneous ruthenium containing catalyst can be separated from the hexahydro-iso-alpha-acid product phase by centrifugation, filtra-tion, decantation or other liquid-solid separation techniques. The hydrogenation process can be performed batch-wise or alterna-tively in continuous mode. | 06-13-2013 |
