Abstract: A process for the thermal-chemical modification treatment of wood is described, in which such a modification is obtained through multiple chemical reactions of the substances comprising the wood structure generated by exposing the wood to temperatures at which the pyrolysis phenomenon begins, i.e., in the range of 180° C.-240° C., in a vacuum autoclave-cell while always maintaining the internal pressure lower than the atmospheric pressure, in a range of values of 70-350 mBar of absolute pressure, consisting in the steps of pre-heating, actual heat treatment, and cooling of a wood mass.
Abstract: A device for regulating the chamber pressure of coking chambers of a coke-oven battery using adjustable iris diaphragms or iris nozzles at the ascending pipe elbow openings in the raw gas receiver. The gas stream flowing from the gas chamber of a coking chamber into the raw gas receiver can thus be regulated so that the pressure in the gas chamber of the coking chamber can be controlled. A method is also disclosed for regulating the gas stream which flows out the gas chamber of a coking chamber, wherein the pressure in the coking chamber is regulated by the control, and wherein also the liquid stream is regulated which serves to wash out the coking gases from the raw gas stream of the coking chamber.

Processing of carbonaceous materials may include dominative pyrolytic decomposition and multiple coil carbonaceous reformation. Dynamically adjustable process determinative parameters may be utilized to refine processing, including process utilization of negatively electrostatically enhanced water species, process utilization of flue gas, and adjustment of process flow rate characteristics. Recycling may be employed for internal reuse of process materials, including recycled negatively electrostatically enhanced water species, recycled flue gas, and recycled contaminants.

A plurality of first heat tubes arranged around and spaced from a central radiant heat tube, the central radiant heat tube having an unsupported end adjacent the door such that whole tires loaded on the cart and through the door will pass over the central radiant heat tube such that the central radiant heat tube is located in a central opening of each tire on the cart.
Abstract: A liquid condensation system heats a liquid raw material under a decompressed circumstance and evaporates a volatile component from a liquid surface to condense the liquid raw material. Therefore, the liquid condensation system includes: liquid condensers, each of which condenses the liquid raw material; a vacuum pump that is in communication with the liquid condensers; and a warm water circulation system as a heating source that heats the liquid raw material in the liquid condensers. The volatile component evaporated in the liquid condensers is led to the outside of the liquid condensers through vapor lines. The condensed liquid that is not evaporated in the liquid condensers is led to the outside of the liquid condensers through condensed-liquid lines. Condensed-liquid-line adjusting valves are interposed on the condensed-liquid lines, and heating means is attached to the condensed-liquid lines. A control unit controls the heating means and the condensed-liquid-line adjusting valves.

Abstract: Garbage and waste of all types that includes or comprises organic matter, particularly including medical waste, plastics, paper, food waste, animal by-products, and the like, can be economically recycled into petroleum products, including oil. Machinery performs a method that mimics natural processes but accomplishes the task in minutes, at rates of about 15 tons per day in a typical processing machine, rather than taking hundreds of thousands of years in nature. The process and apparatus of the invention may chop the waste into small pieces, under negative pressure if appropriate, and then pass the waste into first and then second augers for compression and heating. Destructive distillation occurs, in which large molecular weight hydrocarbons and petrochemicals are heated by hot oil passing through the hollow shaft and by circulating hot, dense, hard material, such as steel balls or fragments or hard rock pieces and such, under pressure with steam, to produce low molecular weight hydrocarbons.

Abstract: Gaseous, liguid and solid fuels are recovered from carbonaceous organic waste material by treating charges of waste material in several successive stages including preheating, drying and conversion into solid and gaseous phases, all as a result of heating in a common vessel or in two or three successive vessels. The solid phases are thereupon cooled prior to admission into a bin, either in a separate vessel or in the vessel for conversion into solid and gaseous phases. The gaseous phases are treated to separate oil from reaction water, combustible gases and inert gases. The charges are heated from without and are sealed from the atmosphere during all four stages of treatment. Each charge is mixed during heating and the intensity of mixing action, the heating action and/or the pressure in the vessel can be varied during one or more stages.
Abstract: Vertically elongate pockets are defined between fixed and horizontally movable vertical refractory walls. When the bottom of the pocket is closed, coal dropped into the pocket from above is compressed between the fixed and movable walls and heated to coking temperature by hot gases in vertical flues extending through the refractory walls. When coked, the moveable wall recedes and the coke therein drops into a shaft furnace below, where devolatilization is complete and the coke is quenched in an inert gas atmosphere, which is totally enclosed to prevent air pollution.
