20100041932 | PROCESS FOR CONVERTING AN OXYGENATED FEED TO HIGH OCTANE GASOLINE - A process of modifying a zeolite catalyst to produce a modified zeolite catalyst wherein the modified zeolite catalyst has blocked pore sites. An oxygenated feed is flowed over the modified zeolite catalyst, wherein the oxygenated feed comprises hydrocarbons, methanol and dimethyl ether or a mixture thereof. The hydrocarbons, methanol and dimethyl ether in the oxygenated feed react with the modified zeolite catalyst to produce cyclic hydrocarbons, wherein the cyclic hydrocarbons produced has less than 10% durene and a median carbon number is C8. | 02-18-2010 |
20110036756 | Novel catalysts and process for liquid hydrocarbon fuel production - The present invention provides a novel process and system in which a mixture of carbon monoxide and hydrogen synthesis gas, or syngas, is converted into hydrocarbon mixtures composed of high quality gasoline components, aromatic compounds, and lower molecular weight gaseous olefins in one reactor or step. The invention utilizes a novel molybdenum-zeolite catalyst in high pressure hydrogen for conversion, as well as a novel rhenium-zeolite catalyst in place of the molybdenum-zeolite catalyst, and provides for use of the novel catalysts in the process and system of the invention. | 02-17-2011 |
20130172650 | UPGRADING LIGHT OLEFINS - Methods and systems relate to upgrading light olefins, such as ethylene, propylene and butylenes, diluted in a gas mixture, such as refinery fuel gas. The upgrading yields products in a gasoline, distillate, lube oil or wax range without requiring purification or compression of the gas mixture prior to feeding the gas mixture to a reactor. In operation, the mixture contacts a solid oligomerization catalyst, such as silica supported chromium, within the reactor. This contact occurs at a first temperature suitable to produce oligomers that are formed of the olefins and adsorb on the catalyst in liquid or solid phases. Next, heating the catalyst to a second temperature higher the first temperature desorbs the oligomers that are recovered and separated into the products. | 07-04-2013 |
