    Abstract: Apparatus and system for producing high pressure gas, such as high pressure coal gas from coal, air and water. Pulverized coal is introduced into a rising stream of steam in a central reaction column of a retort to constitute a fluidized or entrained bed. The coal reacts with the steam to form a gas consisting of hydrogen, carbon monoxide, carbon dioxide, nitrogen, methane and higher hydrocarbons. The retort is constructed so that product gas and air may be burned in an annular chamber surrounding the central reaction column to produce hot flue gas. The hot flue gas is used to drive a turbine which in turn, drives a compressor which introduces compressed air into the annular chamber. Steam tubes may be disposed in the annular space so that the steam introduced to the central reaction chamber may be super-heated by the hot flue gas. The high pressure in the annular chamber enables the pressure within the central reaction column to be relatively high without causing the hot wall surrounding the reaction column to rupture. This is because the high pressure in the central reaction column may be equalized by the high pressure in the annular chamber. The high internal pressure is contained by the cool outer pressure shell which is much more capable of withstanding stress than the hot walls forming the annulas.

    Abstract: A method of processing MSW, either sorted or unsorted, which can be carried out through the use of canisters to hold the waste feedstock, and autoclaves specially designed to process the waste at suitable temperature and pressure combinations is disclosed. The final solid product is a mixture of carbon ash and non-combustible materials, such as, metals, drywall, etc., and syngas that has an enhanced BTU value, typically between about 300 to 700 BTU/ft3. The remainder solid material generally amounts to approximately 5% of the original MSW volume. This material can then be sorted for metals with the balance being sent to a landfill or other recycling processes depending on its composition.

    Abstract: A gasifier for organic solid waste by injection into molten iron and slag bath includes a gasification furnace, a liquid level adjusting furnace and a slag discharge and heat exchange shaft furnace. The liquid level adjusting furnace, in communication with the bottom of the gasification furnace, contains 1200-1700° C. molten iron-based alloy liquid, which is covered with molten liquid slag layer. When gas pressure above or liquid volume in the liquid level adjusting furnace increases, liquid level of the molten liquid in the gasification furnace rises simultaneously. A particle material injection lance is immersed, through which organic particles to be gasified are blown into molten bath, and oxygen gas or oxygen-enriched air as gasifying agent is blown into the melt at the same time. Organic substance is gasified into CO-rich and H2-rich syngas, and most of inorganic substance enters molten slag and is discharged termly.

    Abstract: A reactor system made up of a single canister or a plurality of separate canister sections for the advanced thermal chemical conversion processing of municipal solid waste (“MSW”), either sorted or unsorted, and autoclaves specially designed to process the waste at suitable temperature and pressure combinations is disclosed. The canister sections can be individually and separately filled with compressed bales of MSW or with selected loose MSW. The reactor system can produce syngas that has an enhanced BTU value, typically between about 300 to 700 BTU/ft3. The remainder solid waste material generally amounts to approximately 5% of the original MSW volume. This material can then be sorted for metals with the balance being sent to a landfill or other recycling processes depending on its composition.
