Gradual oxidation with reciprocating engine

摘要

Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.

主权项

1. A split cycle reciprocating engine, comprising:
an intake that receives an air-fuel mixture, the mixture comprising a mixture of air and a gas fuel; a compression chamber, coupled to the reciprocating engine that compresses the mixture in a reciprocating piston chamber, the compression chamber comprising a first outlet; an oxidation chamber that is configured to receive the mixture from the first outlet of the compression chamber via a first inlet and to maintain oxidation of the mixture at an internal temperature beneath a flameout temperature of the mixture and sufficient to oxidize the mixture without a catalyst, the oxidation chamber comprising a second outlet; an expansion chamber, that receives oxidation product gas from the second outlet of the oxidation chamber and expands the product gas within the expansion chamber via a reciprocating piston; a detection module that determines the internal temperature within the reaction chamber; and a correction module that outputs instructions to reduce the internal temperature within the reaction chamber when an adiabatic temperature within the reaction chamber exceeds the flameout temperature of the fuel.
