20140178270 | SABATIER PROCESS AND APPARATUS FOR CONTROLLING EXOTHERMIC REACTION - A Sabatier process involving contacting carbon dioxide and hydrogen in a first reaction zone with a first catalyst bed at a temperature greater than a first designated temperature; feeding the effluent from the first reaction zone into a second reaction zone, and contacting the effluent with a second catalyst bed at a temperature equal to or less than a second designated temperature, so as to produce a product stream comprising water and methane. The first and second catalyst beds each individually comprise an ultra-short-channel-length metal substrate. An apparatus for controlling temperature in an exothermic reaction, such as the Sabatier reaction, is disclosed. | 06-26-2014 |
20140044613 | CATALYTIC ISOBUTANE ALKYLATION - A novel catalytic reactor is provided for controlling the contact of a limiting reactant with a catalyst surface. A first flow vessel defines an interior surface and an exterior surface, and the interior surface has a catalyst deposited on at least a portion thereof. A second flow vessel is positioned within the first flow vessel and the second flow vessel defines a porous surface designed to deliver a fluid uniformly to at least a portion of the interior surface of the first flow vessel. | 02-13-2014 |
20140017583 | PROCESS OF REFORMING A SULFUR-CONTAINING LIQUID FUEL - A process of reforming a liquid fuel comprising from greater than 50 ppmw sulfur to less than 400 ppmw sulfur, the process comprising contacting a liquid hydrocarbon fuel comprising one or more organosulfur compounds in a concentration from greater than 50 ppmw to less than 400 ppmw sulfur with an oxidant and steam or water, the contacting occurring in a catalyst bed comprising a reforming catalyst deposited on an ultra-short-channel-length metal substrate, such that the process is conducted at a peak catalyst temperature greater than 950° C. so as to produce a reformate mixture comprising hydrogen and carbon monoxide. | 01-16-2014 |
20130266903 | APPARATUS AND METHOD FOR VAPORIZING A LIQUID FUEL - An apparatus and process for vaporizing and, optionally, igniting a liquid fuel, preferably, a distillate fuel. The apparatus includes the following components: a heat-conductive reticulated screen positioned within a chamber; a first inlet path into the chamber for delivering a liquid fuel onto the screen; a second inlet path into the chamber for contacting an oxidant with the screen and fuel; a means for heating the screen to a temperature sufficient to vaporize and, optionally, ignite the liquid fuel; and a recuperator in fluid communication with the chamber for transferring heat from the chamber to the second inlet path. The apparatus is suitably employed in compact and portable oxidation reactors, for example, in external combustion engines, catalytic partial oxidation reformers, and hybrid combustors operating in flame and/or catalytic modes. | 10-10-2013 |
20130240789 | REACTOR CONTROL METHOD - A method is provided for controlling the operating temperature of a catalytic reactor using a closed-loop system that provides for varying the reactor input and other operating parameters in order to maintain the operating temperature of the reactor at or near the initial setpoint temperature for operation of the reactor. In one example, maximum and minimum operating temperatures with a catalytic partial oxidation reactor are controlled, as well as maintaining control over the corresponding minimum required ratio of oxygen atoms to carbon atoms, such that the operating temperature within the reactor is maintained below the material limits but above threshold temperatures for coking. | 09-19-2013 |
