Abstract: Implementations of the disclosed subject matter provide a process for producing ethylene glycol from a carbohydrate feed. The process may include contacting, in a reactor under hydrogenation conditions, the carbohydrate feed with a bi-functional catalyst system which may include a heterogeneous hydrogenation catalyst including a magnetically active metal, and a soluble retro-Aldol catalyst including tungstate. A liquid effluent stream may be obtained from the reactor and may include hydrogenation catalyst particles and tungsten oxide precipitate particles. The hydrogenation catalyst particles may be magnetically separated from the tungsten oxide precipitate particles in the liquid effluent stream using a magnet in a separation vessel. The separated hydrogenation catalyst particles may be retained in a separation zone in the separation vessel and may be subsequently removed from the separation zone.
Abstract: The present invention provides a method of treating an exhaust gas comprising methane and NO. The exhaust gas is contacted with a catalyst in the presence of oxygen to oxidize at least part of the methane in the gas stream to carbon dioxide and water and at least part of the NO into NO2 obtaining a treated gas stream. The catalyst comprises one or more noble metals supported on non-modified zirconia, wherein the zirconia comprises tetragonal zirconia and monoclinic zirconia, and wherein the weight ratio of tetragonal zirconia to monoclinic zirconia is in the range of from 1:1 to 31:1.
