摘要： The present invention relates to a process and plant for producing a hydrogen- and carbon oxides-having synthesis gas by partial oxidation of a carbonaceous feedstock having nitrogen compounds. The invention takes advantage of the different solubility of NH3 and CO2 as the synthesis gas stream is cooled. Water is condensed continuously throughout the cooling of the synthesis gas stream. NH3 preferentially dissolves or condenses into the liquid phase during cooling, but at relatively high temperatures, above about 80 to 100° C. Further condensation at lower temperatures then preferentially dissolves or condenses CO2 into the liquid phase. Thus, the formation of ammonium salts during cooling of the synthesis gas is prevented.

摘要： Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

摘要： A gasifier system includes a reactor for receiving a wet feedstock which has a base and a container rotatably connected to the base such that a rotation of the container causes a mixing of the feedstock in an interior of the reactor. The interior is bounded by the base and the container. A space between the base and the container allows an entry of oxygen into the interior. The space has a dimension such that the feedstock is fully oxidized in a combustion area adjacent the base and such that the feedstock avoids combustion in a remainder of the interior. The reactor has a longitudinal axis inclined at an inclination angle relative to a horizontal line to promote the mixing of the feedstock in the interior.

摘要： This invention relates to a power recovery process in waste steam/CO2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.

摘要： An integrated refinery process for the disposal of metal-containing spent coked catalyst from hydrotreating and/or hydrocracking unit operations includes introducing the spent coked catalyst into a membrane wall gasification reactor in the form of flowable particles along with predetermined amounts of oxygen and steam based upon an analysis of the hydrocarbon content of the coke, and optionally, a liquid hydrocarbon; gasifying the feed to produce synthesis gas and a slag material; recovering and subjecting the slag material to further processes in preparation for a leaching step to solubilize and form one or more active phase metal compounds that are recovered from the leaching solution, either separately by sequential processing, or together. The recovered active metal compounds can be used, e.g., in preparing fresh catalyst for use in the refinery's hydroprocessing units.

摘要： A method of producing liquid fuel and/or chemicals from a carbonaceous material entails combusting a conditioned syngas in pulse combustion heat exchangers of a steam reformer to help convert carbonaceous material into first reactor product gas which includes carbon monoxide, hydrogen, carbon dioxide and other gases. A portion of the first reactor product gas is transferred to a hydrogen reformer into which additional conditioned syngas is added and a reaction carried out to produce an improved syngas. The improved syngas is then subject to one or more gas clean-up steps to form a new conditioned syngas. A portion of the new conditioned syngas is recycled to be used as the conditioned syngas in the pulse combustion heat exchangers and in the hydrocarbon reformer. A system for carrying out the method include, a steam reformer, a hydrocarbon reformer, first and second gas-cleanup systems, a synthesis system and an upgrading system.
