Abstract
A hydrocarbon feedstock is decomposed by pyrolysis in a reactor to produce reaction products including solid carbon. At least some of the solid carbon builds up within the reactor. Buildup of the solid carbon within the reactor is removed by combusting a fuel. The fuel may be a portion of the hydrocarbon feedstock itself, or some other fuel.
Claims21
A method of mitigating carbon fouling in a feedstock reactor, comprising:
- decomposing by pyrolysis a hydrocarbon feedstock in the reactor to produce reaction products including solid carbon, wherein at least some of the solid carbon builds up within the reactor;
- and
- removing buildup of the solid carbon within the reactor by combusting a fuel.
A feedstock reactor comprising:
- a burner for combusting a fuel and an oxidant to generate combustion products;
- a choke downstream of the burner to accelerate a flow of the combustion products into a reaction chamber downstream of the choke;
- and
- a computer controller configured to:
- control valving to control a flow of a hydrocarbon feedstock into the reaction chamber, wherein at least some of the feedstock, in response to mixing with the combustion products, is decomposed by pyrolysis into reaction products including solid carbon, wherein some of the solid carbon builds up within the reaction chamber;
- and
- control valving to control a flow of an oxidant into the reaction chamber to mix the oxidant with the hydrocarbon feedstock such that at least some of the hydrocarbon feedstock combusts in response to mixing with the oxidant and thereby removes buildup of the solid carbon.

A feedstock reactor comprising:
- a burner for combusting a fuel and an oxidant to generate combustion products;
- a choke downstream of the burner to accelerate a flow of the combustion products into a reaction chamber downstream of the choke;
- one or more offboard combustors connected to the reaction chamber;
- and
- a computer controller configured to:
- control valving to control a flow of a hydrocarbon feedstock into the reaction chamber, wherein at least some of the feedstock, in response to mixing with the combustion products, is decomposed by pyrolysis into reaction products including solid carbon, wherein some of the solid carbon builds up within the reaction chamber;
- and
- control the one or more combustors to combust a fuel-oxidant mixture in each combustor to generate combustion products that flow into the reaction chamber and remove the buildup of solid carbon.
