Abstract

A pyrolysis process comprises introducing one or more chemical reactants into a reactor containing a liquid maintained at a high temperature, producing chemical products in the liquid based on the high temperature, allowing the solid product to grow in particle size, accumulating the solid product in the liquid, and removing the solid product from the reactor while retaining a substantial portion of the liquid within the reactor. The chemical products comprise a solid chemical product that is mixed with the liquid.

Abstract

A method of preheating a feed to a molten material reactor comprises heating a hydrocarbon feed in a first heat exchanger using a cooled product gas to produce a heated hydrocarbon feed stream, pyrolyzing at least a portion of the C2+ hydrocarbons in the heated feed stream in a pyrolysis reactor to produce a pyrolyzed hydrocarbon stream, and heating the pyrolyzed hydrocarbon stream in a second heat exchanger using a product gas to produce a pre-heated feed gas. The heated hydrocarbon feed stream comprises methane and one or more C2+ hydrocarbons.
