Chemistry: fischer-tropsch processes; or purification or recovery of products thereof inventions 06/06

20060142400 - Method for producing long-chain hydrocarbons from natural gas: Natural gas is reacted with steam, to generate carbon monoxide and hydrogen in a first catalytic reactor; the resulting gas mixture is used to perform Fischer-Tropsch synthesis in a second catalytic reactor. After performing Fischer-Tropsch synthesis, the remaining hydrogen is separated from a hydrocarbon-rich stream using a hydrogen-permeable membrane, and...

20060142401 - Partial boiling in mini and micro-channels: The invention provides methods, apparatus and systems in which there is partial boiling of a liquid in a mini-channel or microchannel. The partial boiling removes heat from an exothermic process....

20060135630 - Producing longer-chain hydrocarbons from natural gas: Natural gas is reacted with steam, to generate carbon monoxide and hydrogen in a first catalytic reactor (16); the resulting gas mixture is used to perform Fischer-Tropsch synthesis in a second catalytic reactor (26). After cooling the resulting gas stream in a heat exchanger (29), the remaining gas stream (30)...

20060135629 - Production of hydrocarbons: A process for production of hydrocarbons including a) reforming a divided hydrocarbon feedstock stream, mixing the first stream with steam, passing the mixture over a catalyst disposed in heated heat exchange reformer tubes to form a primary reformed gas, forming a secondary reformer feed stream including the primary reformed gas...

20060135631 - Catalyst recover from a slurry: Embodiments of the invention relate to processes and apparatus for the washing and recovery of metal-containing catalyst solids in a form suitable for reclamation. More specifically, a catalyst recovery process comprises removing an organic residue with a washing medium from a metal-containing catalyst solids, recovering washed solids, and treating the...

20060135632 - Oxygenate to olefin manufacture and recovery process: This invention is directed to methods for forming an olefin stream from a methanol stream. A lower grade methanol, such as chemical grade or crude methanol, can be used as feed to form the olefin stream. The process uses a relatively simple distillation type step to vaporize a portion of...

20060128818 - Process and apparatus for the production of synthesis gas: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in...

20060116430 - Method for the production of hydrocarbon liquids using a fischer-tropf method: Methods for converting hydrocarbon gases into hydrocarbon liquids through Fischer-Tropsch methods. In addition to liquid hydrocarbons, a waste gas containing hydrogen, carbon dioxide, and hydrocarbons with less than 6 carbon atoms, is produced. The waste gas is separated and several gas streams are produced. One such gas stream contains methane,...
