    摘要: This invention relates to a power recovery process in waste steam/CO2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.

    摘要: Process control parameters for production of hydrogen and FT products by steam/CO2 reforming include controlling steam reformer temperature, addition of steam, CO and optionally, biogas. Optimization of parameters have resulted in increased production of H2, removal of sulfur and halogen contaminants, and control of the H2/CO ratio for efficient generation of Fischer-Tropsch products.

    摘要: Methods and apparatus for compact and easily maintainable waste reformation. Some embodiments include a rotary oven reformer adapted and configured to provide synthesis gas from organic waste. Some embodiments include a rotary oven with simplified operation both as to reformation of the waste, usage of the synthesized gas and other products, and easy removal of the finished waste products, preferably in a unit of compact size for use in austere settings. Yet other embodiments include Fischer-Tropsch reactors of synthesized gas. Some of these reactors include heat exchanging assemblies that provide self-cleaning effects, efficient utilization of waste heat, and ease of cleaning.

    摘要: What has been achieved by this invention is a method and design of providing high temperature heat for an endothermic gasifier without combustion using electrical resistance immersion heating element technology. Further, these elements could be heated by three phase electrical power; thus, minimizing the number of electrical leads emerging from the top of the heating elements.This invention solves the difficulty of designing the steam/CO2 reforming reactor with a large number of densely packed heating elements and the syngas heat recuperator into one reactor. This is done to avoid the extremely hot syngas leaving the reactor from melting the downstream metal fittings carrying the reactor product gases to the downstream piping process.

    摘要: A method and design of providing high temperature heat for an endothermic gasifier without combustion includes flowing a stream of a first hydrocarbon gas sequentially through an annular plenum and a cylindrical plenum while heating the gas using electrical resistance immersion heating elements. These heating elements may be heated by three phase electrical power, minimizing the number of electrical leads emerging from the top of the heating elements. This method and design reduces the risk of extremely hot syngas exiting the gasifier damaging downstream fittings.
