20100087615 | Process for the oxidative dehydrogenation of ethane - A method for producing a mixture of ethylene and carbon monoxide by contacting ethane and an oxygen source with a catalyst comprising synthetic cryptomelane or octahedral molecular sieve. The method further comprises condensing the alkyl propionate with formaldehyde to produce an alkyl methacrylate. | 04-08-2010 |
20130267735 | Propane Oxidation Process Using Reduced Amounts of Steam - Less propionic acid is produced as a by-product in a process for the direct oxidation of propane to acrylic acid, the process comprising the step of contacting under oxidation conditions a gaseous mixture comprising (i) propane, (ii) oxygen, (iii) steam and (iv) a diluent gas, with a propane oxidation catalyst by reducing the steam content of the gaseous mixture. | 10-10-2013 |
20130274509 | Reactor and Process for Propane Oxidation - The amount of propionic acid produced in the process of oxidizing propane to acrylic acid is reduced by using a reactor with a length/diameter ratio >10 and/or maintaining the difference between the target reaction temperature and the peak temperature within the reactor to less than 20° C. | 10-17-2013 |
20140243554 | METHOD FOR PREPARING ACRYLIC ACID FROM PROPANE AND PROPYLENE - The application concerns a process comprising: (A) contacting a gas comprising oxygen, propane and propylene with at least one catalyst under reaction conditions sufficient to at least partially convert the propylene into a final product comprising acrylic acid; (B) feeding said final product to a separation column, in which the final product is split into a liquid stream, which is rich in acrylic acid, and a gaseous by-product stream comprising propane and propylene in a volume ratio of from 99.9:0.1 to 95:5; (C) contacting the gaseous by-product stream with oxygen in the presence of a catalyst under reaction conditions sufficient to at least partially convert propane to acrylic acid. | 08-28-2014 |
20140350298 | PROCESS FOR THE (AMM)OXIDATION OF LOWER MOLECULAR WEIGHT ALKANES AND ALKENES - A process for producing unsaturated carboxylic acids or unsaturated nitriles by vapor phase oxidation reaction of their corresponding C | 11-27-2014 |
