Abstract: The invention is an apparatus and method to remove hydrogen sulfide and siloxanes from biogas and destroy the contaminants in microwave reactors. Hydrogen sulfide and siloxane are removed from biogas using an adsorbent media such as activated carbon. The media is regenerated in a microwave reactor where the hydrogen sulfide and siloxane are removed in a sweep gas. In one process, siloxane is oxidized to silicon dioxide in a second microwave reactor and removed with a filter. Hydrogen sulfide if first oxidized to sulfur dioxide, then reduced to sulfur in a third microwave reactor and removed with a filter. In another process, siloxane is combined with water to form silicon dioxide and hydrogen sulfide is reduced to elemental sulfur in a microwave reactor. These reactants are removed with a filter. The remaining sweep gas containing hydrogen and low molecular weight hydrocarbons is returned to the biogas stream.

Abstract: A process of forming hydrogen and a carbon product, for example carbon black. A hydrocarbon-containing input gas, for example methane, is passed through a reaction bed in a microwave reaction chamber irradiated with microwave radiation. The reaction bed comprises a particulate material comprising at least one of a metal or metal compound and a carbon material.

Abstract: A system and method for destruction of energetic compounds, medical wastes and unwanted pharmaceuticals using microwave energy. Waste materials are first mixed into a dilute water solution, slurry or emulsion. The dilute waste flows to a first microwave reactor containing silicon carbide. The silicon carbide absorbs the microwave energy, heats and vaporizes the liquid. The vapor flows to a second microwave reactor containing silicon carbide and an oxidation catalyst. Air is added and the waste portion of the vapor is oxidized to carbon dioxide. Water is recovered in a condenser and recycled. Carbon dioxide and remaining air is vented. Solid organic wastes such as contaminated disposable gloves and towels are gasified in a first microwave reactor with air and oxidized in the second microwave reactor.
