Abstract: A reactor layout for a process of methanol production from low quality synthesis gas, in which relatively smaller adiabatic reactors can be operated more efficiently, some of the inherent disadvantages of adiabatic reactors for methanol production are avoided. This is done by controlling the outlet temperature in the pre-converter by rapid adjustment of the recycle gas, i.e. by manipulating the gas hourly space velocity in the pre-converter.

Abstract: In a novel method for start-up heating of a converting re-actor in an ammonia synthesis plant, the conventional use of a gas fired heater is replaced by inductive heating. The inductive heating is obtained using an alternating high frequency current, which is passed through an inductive coil located inside the reactor, especially mounted inside a pressure shell. The method makes it possible to run reactions at high temperatures and high pressures in a very efficient way.

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.
