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.

A stillage clarification process and related system include using hydrocyclones and high recovery disc centrifuges for fractionation of stillage from a grain ethanol plant and splitting the stillage into fractions with mass and compositional assays per bushel of grain processed. The fractions include a first fraction comprising 45% to 70% protein and 3% to 8% fat, a second fraction comprising distillers corn oil, a third fraction comprising a fiber having made up of approximately 22% to 28% protein and less than 8% fat, and a fourth fraction comprising at least 30% soluble protein and less than 3% fat.

The reaction rate of hydrocarbon pyrolysis can be increased to produce solid carbon and hydrogen by the use of molten materials which have catalytic functionality to increase the rate of reaction and physical properties that facilitate the formation and contamination-free separation of the solid carbon. Processes, materials, reactor configurations, and conditions are disclosed whereby methane and other hydrocarbons can be decomposed at high reaction rates into hydrogen gas and carbon products without any carbon oxides in a single reaction step. The process also makes use of specific properties of selected materials with unique solubilities and/or wettability of products into (and/or by) the molten phase to facilitate generation of purified products and increased conversion in more general reactions.
