Dbb Fuel Cell Engines, June 23, 1999: EP0924163-A2 (9 worldwide citation)

Heating takes place during cold start-up. In a first phase of operation, the catalytic combustor (11a, 11b, 11c) in thermal contact with the reformer (1) and evaporator (2) is heated above the boiling point of water, by catalytic combustion of hydrocarbon and/or hydrogen with an oxidant gas. In the ...

Heil Dietmar, Strobel Barbara, Wiesheu Norbert, Zur Megede Detlef Dr, Benz Uwe: Process and apparatus for selective catalytic oxidation of carbon monoxide. Daimler Benz, June 4, 1997: EP0776861-A1 (6 worldwide citation)

The CO in a flowing gas mixture contg. H2 is catalytically oxidised in an appts. that first reduces its temp. with the help of static mixer structures as it enters the reactor and then feeds in an oxidising gas through several inlets, at a rate that depends on the operational parameters. The reactor ...

Heil Dietmar Dipl Ing, Benz Uwe Dipl Ing: Two stages methanol reforming. Daimler Benz, December 20, 1995: EP0687648-A1 (6 worldwide citation)

An assembly reconstitutes methanol using steam in a converter having a number of catalyst-filled tubes surrounded by a heating medium. The novelty is that each reaction tube (3) is surrounded by a second concentric outer tube (5) to form a passage (4) through which the heating medium flows. Further ...
