Various aspects of a process for producing energy and fuel from municipal refuse, e.g. a screw press for refuse compaction

摘要

Various aspects of a process for producing energy and fuel from municipal refuse are claimed, e.g. a screw press comprising a porous body in a sealed tube from which a vacuum pump can extract air from the refuse during compaction. The following aspects of a process for producing energy and fuel from municipal refuse are claimed: (1) a screw press comprising a porous body in a sealed tube from which a vacuum pump can extract air from the refuse during compaction; (2) use of gas capable of producing atomic carbon, oxygen and hydrogen by molecular dissociation as a plasma-generating gas; (3) use of slag from electric foundry furnaces to fix solid carbon ejected by the plasma arc; (4) injection by screw press of the necessary amount of slag plus 12 g of coke or graphite per mole of carbon dioxide used as plasma-generating gas; (5) use of gas or methanol burners to gasify or burn solid carbon; (6) the number of moles of carbon dioxide dissociated by the plasma is a function of the intended aim; (7) the plasma is maintained at a temperature sufficient to fuse all inorganic materials; (8) the gasification temperature is controlled by injecting carbon monoxide and water; (9) substances necessary for desired chemical transformations are added to the refuse during compaction; (10) the plasma is optionally rotated by supplying 3x torches (x is greated than 1) with x-phase alternating current; (11) the spouts of the reactor are heated by induction; (12) the heat exchanger is protected from hydrogen chloride by a quartz plasma; (13) hydrogen is separated by molecular membrane techniques after cooling the gas by scrubbing; (14) the heating value lost by hydrogen removal is restored by adding methane produced from refuse; (15) the gas turbine temperature is controlled by injecting carbon dioxide into the synthesis gas and spraying water into the combustion chamber; (16) natural gas is added to the turbine exhaust gas to produce methanol; (17) the methanol can be used in fuel cells equipped with a reformer; (18) deuterium and hydrogen are produced by electrolysis of water using the excess electricity production; (19) the hydrogen is used as a fuel for zero emission automobiles.
