Decomposition reactor for pyrolysis of hydrocarbon feedstock
20230107846 · 2023-04-06 ·

A multi-stage decomposition reactor and method for thermochemical decomposition (pyrolysis, cracking, direct decomposition) of a hydrocarbon feedstock of various compositions that may include mixtures. The feedstock in a supply flow passing through a heating stage is activated by raising its temperature to a decomposition temperature, dependent on the nature of the feedstock. The physical length of the heating stage and a velocity of flow once activated are tuned such that a heating residence time of the flow is shorter than an average decomposition onset time at the decomposition temperature (e.g., before 1% or more feedstock decomposition). The heating stage is followed by a decomposition stage that supports a decomposition residence time that is longer than the average decomposition onset time. A molten material can be present in the decomposition stage that can be rotated to facilitate mopping up of carbon depositions.
