A furnace for performing an endothermic process comprises tubes containing a catalyst for converting a gaseous feed, said tubes positioned inside the furnace, inner burners mounted to a furnace roof between the tubes, and outer burners mounted to the furnace roof between the tubes and a furnace wall. The outer burners are positioned close to the furnace wall, and configured to operate with 45-60% of the power of the inner burners and with an inlet velocity between 90 to 110% of the inlet velocity of the inner burners.

A combustor, including: a catalyst bed portion supporting a catalyst capable of promoting a combustion reaction of fuel; a vaporizer which is arranged on the downstream side of the catalyst bed portion with respect to a flow of the fuel going through the catalyst bed portion and is configured to be able to use a combustion gas generated from the combustion reaction as a hot fluid; a manifold portion which is outside the catalyst bed portion and guides air in a direction opposite to the flow of the fuel going through the catalyst bed portion and has a wall portion on which a sidewall of the vaporizer is projected; and a fuel introducing portion configured to penetrate the wall portion of the manifold portion so that the fuel evaporated by the vaporizer can be introduced into the manifold portion.

A gas treatment system includes a first scrubber, a regenerative catalytic oxidizer (RCO) that treats gas that passes through the first scrubber, a second scrubber that treats the gas that passed through the regenerative catalytic oxidizer, and a dielectric barrier discharge (DBD) plasma reactor that treats the gas that passed through the second scrubber. The regenerative catalytic oxidizer includes a two-bed regenerative catalytic reactor.

A catalyst bed includes a structure defining a plurality of channels configured to receive flow of fluid to be chemically catalyzed. The plurality of channels are oriented at least partially non-parallel to an overall flow direction of the flow from inputs of the plurality of channels to outputs of the plurality of channels. A catalyst is exposed at an exterior of the structure.
