Reactor systems and processes for light hydrocarbon catalytic cracking to produce high value hydrogen and solid carbon

Abstract

A process for producing high purity solid carbon includes contacting a first portion of a spent carbon supported metal catalyst comprising one or more active metal compounds and solid carbon deposits derived from catalytically cracking a light hydrocarbon feedstock in the presence of a carbon supported metal catalyst comprising one or more active metal compounds in a reactor with a leaching solution to solubilize the one or more active metal compounds from the first portion of the spent carbon supported metal catalyst to generate a solubilized leaching solution comprising solubilized one or more active metal compounds and a solid carbon product, and separating the solid carbon product from the solubilized leaching solution to generate the solid carbon product and a separated solubilized leaching solution comprising the solubilized one or more active metal compounds. The solid carbon product is a high purity solid carbon product.
