Publication number: 20220017826Abstract: 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.Type: ApplicationFiled: December 6, 2019Publication date: January 20, 2022Applicant: Raven SR, LLCInventor: Terry R. Galloway

Publication number: 20210207036Abstract: 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.Type: ApplicationFiled: December 20, 2020Publication date: July 8, 2021Applicant: Raven SR LLCInventor: Terry R.

Publication number: 20200406216Abstract: Method 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.Type: ApplicationFiled: July 1, 2020Publication date: December 31, 2020Applicant: Raven SR, LLCInventors: Terry R. Galloway, Joseph Oscar Waidl

Patent number: 10479680Abstract: 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.Type: GrantFiled: January 14, 2016Date of Patent: November 19, 2019Assignee: Raven SR, LLCInventor: Terry R.
