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.

Provided is a powder fuel supply apparatus comprising a distributor (84) that branches supplied powder fuel to a plurality of branch tubes (82), a plurality of burners (126a) connected to downstream ends (82a) of the plurality of branch tubes (82), respectively, to supply char into a gasification furnace that gasifies the powder fuel, a flow nozzle (85) provided in each of the plurality of branch tubes (82), to apply pressure loss to char flow in the branch tube (82), a differential pressure gauge (86) that measures a differential pressure generated by the flow nozzle (85), and a control unit that determines decrease in flow velocity of the char flow based on the differential pressure obtained by the differential pressure gauge (86).

An object is to curb damage localized in a slag capturing portion caused when slag passes therethrough. A slag discharge device includes: a screen mesh (6) that is a porous member including a plurality of through-holes (6a) formed therein; and a crushing device (7) that crushes water-granulated slag (S2) captured by the screen mesh (6). The crushing device has a crusher head (12) that breaks, with a pressure, and thus crushes the water-granulated slag (S2), a hydraulic cylinder (13) that reciprocates the crusher head in a predetermined direction, a guide plate (14) that restricts movement of the crusher head caused by the hydraulic cylinder, and a plurality of crushing spaces (15) in which the water-granulated slag (S2) is crushed. A communication opening that causes the crushing spaces (15) to communicate with each other is formed in a partitioning wall guide plate (14a) of the guide plate.

A method for processing feedstock is described, characterized in that incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock. In some embodiments the incoming feedstock is comprised of mixed solid waste, such as municipal solid waste (MSW). In other embodiments the incoming feedstock is comprised of woody biomass. In some instances, the incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% and greater suitable for conversion into biogenic carbon Fischer Tropsch liquids. The high biogenic carbon Fischer Tropsch liquids may be upgraded to biogenic carbon liquid fuels. Alternatively, the incoming feedstock is processed to selectively recover plastic material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% or less.

A system and method for converting biomass to energy in a multi-objective application that includes generating power, heat, and multiple cooling applications. Waste heat from a HCCI engine is used to implement the multiple cooling applications of an ejector refrigeration cycle and a trans-critical refrigeration cycle, process heating, and turbine power production.

This invention relates to a power recovery process in waste steam/CO.sub.2 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.
