Abstract: A fuel cell reactor, preferably a solid oxide fuel cell (SOFC) reactor, for performing direct conversion of a hydrocarbon-containing gas to a higher hydrocarbons product is confined by walls, where reactants are flown in the anode compartments and air is introduced to the cathode compartments, and where oxygen is transferred from one side of the walls to the other side to promote or inhibit a chemical reaction. The process for direct conversion of a hydrocarbon-containing gas to a higher hydrocarbons product takes place in the anode compartment of the reactor, in which produced hydrogen, limiting the conversion to the equilibrium, is reacted in situ with oxygen ions transferred from the cathode compartment to produce steam, thereby removing the equilibrium-limiting hydrogen from the reaction.

Abstract: Process for the conversion of oxygenates to C5+ hydrocarbons boiling in the gasoline boiling range, comprising the steps of continuously a) providing one or more feed streams of one or more oxygenate compounds; b) heating the one or more feed streams to an inlet temperature of one or more downstream conversion reactors; c) introducing the one or more heated feed stream into inlet of the one or more conversion reactors; d) converting in the one or more conversion reactors the one or more heated feed stream in presence of catalyst to a converted oxygenate product comprising C5+ hydrocarbons; e) withdrawing from the one or more conversion reactors the converted oxygenate product; f) determining at outlet of the one or more conversion reactors amount of the one or more unconverted oxygenate compounds in the withdrawn converted oxygenate product; g) separating the converted oxygenate product into a C4− hydrocarbon fraction, a fraction with the C5+ hydrocarbons boiling in the gasoline boiling range and a fraction comprising water and the one or more unconverted oxygenate compounds, wherein the inlet temperature of the one or more feed streams in step b is continuously adjusted to maintain a constant amount of the one or more unconverted oxygenate compounds as determined in step f.

Abstract: In a process for producing hydrogen or syngas by methanol cracking, whereby methanol is catalytically decomposed into hydrogen and carbon monoxide in an endothermal reaction, said reaction takes place in a reactor with direct inductive heating in the reaction zone. The heating is obtained by passing an alternating current through a metallic coil located inside the reactor or by using induction heated catalyzed hardware in the shape of a ferromagnetic structure, which is coated with an oxide impregnated with the catalytically active phase.
