Abstract
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.
Claims22
A waste reformation system comprising:
- a synthesis reactor for producing a first stream of synthesized gas;
- a waste reforming conversion system for receiving at least organic waste and for producing a second stream of synthesized gas, the waste reforming conversion system including a rotatable outer wall including a helical spiral flight affixed to an interior of the outer wall and a non-rotatable reactor containing a steam reformer, the non-rotatable reactor located within the rotatable outer wall;
- and
- a heat engine in fluid communication with the waste reforming conversion system, wherein gases from the heat engine are supplied to the waste reforming conversion system;
- wherein the synthesis reactor is in fluid communication with the waste reforming conversion system such that a first portion of the first stream is mixed with the organic waste prior to the organic waste being received by the waste reforming conversion system;
- and
- wherein the waste reforming conversion system is in fluid communication with the synthesis reactor such that the second stream is used for producing the first stream.
A waste reformation system comprising:
- a synthesis reactor for producing a first stream of synthesized gas;
- a waste reforming conversion system for receiving at least organic waste and for producing a second stream of synthesized gas, the waste reforming conversion system including
- two opposing ends with a waste entrance and an exit for the second stream of synthesized gas at one end and a reactor containing a steam reformer and an exit for solid waste at the other end, and
- a rotatable outer wall including a helical spiral flight affixed to an interior of the outer wall,
- wherein the spiral flight and the rotatable outer wall combine to create an internal gas passage for flowing the second stream of synthesized gas from the reactor to the exit for the second stream of synthesized gas;
- and
- a heat engine in fluid communication with the waste reforming conversion system, wherein gases from the heat engine are supplied to the waste reforming conversion system;
- wherein the synthesis reactor is in fluid communication with the waste reforming conversion system such that a first portion of the first stream is mixed with the organic waste prior to the organic waste being received by the waste reforming conversion system;
- and
- wherein the waste reforming conversion system is in fluid communication with the synthesis reactor such that the second stream is used for producing the first stream.
