| 20080200730 | PROCESS FOR PREPARING METHYL MERCAPTAN FROM DIALKYL SULPHIDES AND DIALKYL POLYSULPHIDES - A process for continuously preparing methyl mercaptan by reacting a reactant mixture which contains a dialkyl sulphide and a dialkyl polysulphide with hydrogen sulphide to give methyl mercaptan. | 08-21-2008 |
| 20080214384 | PROCESS FOR REGENERATING A CATALYST - A process for regenerating a catalyst used in the preparation of acrolein from glycerol, which comprises tungsten compounds and has acidic properties and at least one promoter. | 09-04-2008 |
| 20080262270 | CATALYST FOR THE PREPARATION OF METHYL MERCAPTAN - The present invention refers to a catalyst for the manufacture of methyl mercaptan from carbon oxides comprising Mo and K compounds and oxides or sulfides of metals chosen from the manganese group. The improvement of the present process consists of the fact that carbon dioxide can be converted with higher conversions and selectivities to methyl mercaptan as compared to state-of-the-art technologies, with only minor amounts of carbon monoxide being formed as side product. Simultaneously, carbon monoxide can be easily converted into carbon dioxide and hydrogen by reaction with water using established water-gas-shift-technologies thus increasing the overall selectivity to methyl mercaptan. | 10-23-2008 |
| 20090054691 | PROCESS FOR PREPARING METHYL MERCAPTAN - The present invention relates to a process for continuously preparing methyl mercaptan from hydrogen sulphide and methanol in a direct connection with the preparation of hydrogen sulphide. | 02-26-2009 |
| 20090306432 | CATALYST FOR THE SYNTHESIS OF ALKYL MERCAPTAN AND PROCESS FOR THE PRODUCTION THEREOF - The invention relates to an oxidic catalyst containing cesium and tungsten for the synthesis of alkyl mercaptans from alkanols and hydrogen sulfide, and to a process for the production of this catalyst, wherein the molar ratio of cesium to tungsten is <2:1. | 12-10-2009 |
| 20100041548 | PROCESS FOR THE MANUFACTURE OF METHYLMERCAPTAN - The present invention refers to a continuous process for the manufacture of methyl mercaptan using Mo—O—K-based catalysts. It is further described that the total selectivity of methylmercaptan can be increased by at least 1% by lowering the total gas hourly space velocity. The invention further refers to a process for the preparation of a solid, preformed catalyst system. | 02-18-2010 |
| 20100113833 | Novel Catalysts and Process for Dehydrating Glycerol - A process for preparing acrolein from glycerol using an acidic solid-state catalyst which comprises tungsten compounds and further promoters. | 05-06-2010 |
| 20100248952 | CATALYSTS CONTAINING TUNGSTATE FOR THE SYNTHESIS OF ALKYL MERCAPTAN AND METHOD FOR THE PRODUCTION THEREOF - The invention relates to a catalyst containing alkali tungstate for the synthesis of alkylmercaptanes from alkanols and hydrogen sulphide, in addition to a method for the production of said catalyst, wherein the molar ratio of alkali to tungstan is <2:1. | 09-30-2010 |
