    Abstract: A system for production of a synthesis gas, including: a synthesis gas generation reactor arranged for producing a first synthesis gas from a hydrocarbon feed stream; a post converter including a catalyst active for catalyzing steam methane reforming, methanation and reverse water gas shift reactions; the post converter including a conduit for supplying a CO2 rich gas stream into a mixing zone of the post converter, where the CO2 rich gas stream in the conduit upstream the mixing zone is in heat exchange relationship with gas flowing over the catalyst downstream the mixing zone; a pipe combining the at least part of the first synthesis gas and the CO2 rich gas stream to a mixed gas, in a mixing zone being upstream the catalyst; wherein the post converter further includes an outlet for outletting a product synthesis gas from the post converter. Also, a corresponding process.

    Abstract: A reactor system for carrying out an endothermic reaction of a feed gas, including: a structured catalyst arranged for catalyzing the endothermic reaction of a feed gas, the structured catalyst including a macroscopic structure of electrically conductive material, the macroscopic structure supporting a ceramic coating, wherein the ceramic coating supports a catalytically active material; a pressure shell housing the structured catalyst; heat insulation layer between the structured catalyst and the pressure shell; at least two conductors electrically connected to the electrically conductive material and to an electrical power supply placed outside the pressure shell, wherein the electrical power supply is dimensioned to heat at least part of said structured catalyst to a temperature of at least 200° C. by passing an electrical current through the electrically conductive material. Also, a process for performing an endothermic reaction of a feed gas.

    Abstract: A tube heat exchange reactor for carrying out an endothermic catalytic reaction. The tube heat exchange reactor includes: an outer tube with a first and a second end, where the first end is an inlet end and where the second end is a closed end, an inner tube coaxially arranged within the outer tube and spaced apart from the outer tube, where at least a part of the inner tube holds a bed of catalyst material susceptible for induction heating and where the inner tube has an inlet end and an outlet end, an induction coil placed within the annular space confined between the outer and the inner tube, and a power source arranged to supply alternating current to the induction coil in order to generate an alternating magnetic field within at least a part of the inner tube.

    Abstract: A process for the conversion of natural gas to hydrocarbon products by (a) mixing natural gas with a small amount of hydrogen, (b) purifying the mixture from (a) to obtain purified natural gas, (c) mixing the purified natural gas from (b) with steam to obtain the desired steam-to-carbon (S/C) ratio, (d) mixing the natural gas/steam mixture from (c) with tail gas from the downstream Fischer-Tropsch synthesis and converting the mixture into a synthesis gas, (e) cooling the synthesis gas from (d) and condensing out the process water from it, (f) leading the dry synthesis gas from (e) to a carbon dioxide removal section, and (g) sending the CO2-deprived synthesis gas to the downstream Fischer-Tropsch synthesis unit as a make-up gas. The carbon dioxide removed from the syngas in step (f) is either vented or kept for other use without any part of it being recycled.
