Abstract: An electrical heating coal material decomposition apparatus includes a closed kiln body with a feed inlet, a discharge outlet, and an electrical heating device arranged in the kiln body. A propulsion and decomposition path of coal material is formed between the electrical heating device and the inner wall of the kiln body. A coal decomposition gas collecting pipe communicates with the propulsion and decomposition path of coal material, and is connected with a gas dust-trapping and liquefying device arranged outside the kiln. The electrical heating device transfers heat to the pulverized coal inside the propulsion and decomposition path of coal material by conduction and irradiation. The pulverized coal absorbs sufficient heat and decomposes into fuel gas, tar gas and coal. The fuel gas and tar gas enters the gas dust-trapping and liquefying mechanism through the decomposed gas collecting tube, where they are collected, dust-trapped, separated and liquefied under pressure.

Abstract: A reactor for converting organic feed is provided. A retort extends through the furnace of the reactor. The retort has a retort auger, an inlet and an outlet. The reactor includes a charcoal delivery assembly having a collection line, delivery line, and a transfer zone. The collection line is adjacent to the outlet of the retort receives charcoal from the retort, and contains a collection auger with a flighted portion extending at least partially therethrough. The delivery line is connected to a downstream portion of the collection line and has a flighted delivery auger extending therethrough. The transfer zone is a space, between a downstream end of the flighted portion of the collection auger and an upstream end of the flighted delivery auger, where charcoal collected and delivered by the collection auger forms a plug, thereby blocking biogas from the retort from entering the delivery line.

Abstract: One embodiment of a method of recycling a plastic material includes heating a plastic material in a treatment chamber in incremental steps through a series of graduated temperature set points wherein each graduated temperature set point corresponds to a vaporization temperature of an individual by-product of said plastic material, and pulling a vacuum of inert gas on the treatment chamber at each temperature set point to selectively remove an individual by-product corresponding to the temperature set point.

Abstract: A wood gasification apparatus in which cellulosic material is transported by an auger through a housing and heated to vaporize at least a portion of the cellulosic material by frictional heating. The auger and housing define a spiral void through which the cellulosic material is propelled from the inlet to the outlet, and which continually decreases in volume from the inlet to the outlet. The ever decreasing volume of the void increases the pressure on the cellulosic material and maximizes the frictional heating until the material reaches a vaporization temperature.

Abstract: The invention relates to a method and a device for evacuating hot raw gases which occur in the oven chambers of a coke oven battery during coking. The oven gases are lead from the oven chambers into a hot gas collector. The pressure in the oven chambers is controlled by shut-off and throttling devices which are arranged in the hot gas streams between the raw gas outlet of the oven chambers and the hot gas collector. The positions of the devices are controlled according to the pressure that is measured in the allocated oven chamber. The gas of the hot gas collector is supplied to a steam boiler firing or a fission reactor.

The liquid and the majority of gas are drawn off from the pyrolysis reactor. Discharge apparatus connected to the pyrolysis reactor converts the remaining gas to a condensate and discharges the metal. The condensate is also removed for further use.

Abstract: Apparatus for the thermal conversion of solids containing hydrocarbons. In one embodiment for solids which can be converted entirely to vapour, pieces of the solids are continually fed into a molten lead bath in an oxygen free atmosphere in an elongated conversion chamber. An auger partially immersed in the lead bath carries the floating pieces along in the molten lead bath until they are gradually converted to hydrocarbon vapour which rises upwardly to a condenser. In another embodiment for solids which can be converted to a vapour, particulate matter and residual solids, the lead bath extends further into a separation chamber with an inclined retaining skirt extending between the conversion chamber and the separation chamber, The auger forces the particulate matter and residual solids remaining after vaporization down under the inclined skirt, but the hydrocarbon vapour is prevented from escaping into the separation chamber.

Abstract: A rotary, continuous pyrolytic conversion system converts solid hydrocarbon containing feedstocks into gases, liquid hydrocarbons and char. A converter drum is contained within an outer drum which is in substantially air-tight relationship with an injector for introducing the feedstock in the form of bales and with a discharge chute for the solid products of pyrolysis. A casing around the outer stationary drum defines an oven chamber which is heated by combustion products. A rod extends into the injection end of the converter drum for supporting scrapers against the inner periphery of the converter drum. A crusher bar is carried in the drum at the discharge end thereof and crushes the solid products. A second pyrolysis reactor may receive the solid pyrolysis products and be operative at higher temperature than the first converter to destroy chlorinated hydrocarbons.

Abstract: A dry sealing leg apparatus is comprised of four chambers through which a moving bed of retorted shale particulates from an oil shale retort is passed serially: a surge chamber, a gas injection chamber, a seal leg chamber, and a gas disengaging chamber. In the gas injection chamber, a sealing gas penetrates the moving bed of shale and divides into two portions. One portion travels countercurrently to the shale through the surge chamber and enters the retort at a positive pressure to seal product gases therein. A second portion travels co-currently with the shale through the seal leg chamber and gas disengaging chamber and exits at a pressure less than that of the retort, having been reduced in pressure by resistance to its passage through the shale.
