Abstract: Disclosed is a method for generating steam and manufacturing a product gas by catalytically reacting a feed gas in a reactor unit comprising a reactor tube. Said method encompasses the following steps:—a catalyst bed is conveyed through the reactor tube;—the feed gas is allowed to flow into the catalyst bed against the direction of travel of the catalyst bed;—a temperature profile is regulated along the reactor tube by thermally insulating, heating, and/or cooling regulation sections in the reactor tube; and—the waste heat generated in one of the regulation sections by the cooling action is transferred from the reactor tube to a steam generation unit. The feed gas can be syngas and especially biogas.

Abstract: A power supply unit for a computer system is proposed which has at least one data memory unit, which provides data specific to the power supply unit, for system controllers in the computer system. This achieves the object of offering the capability of ensuring that the power supply unit is not overloaded or underloaded, or that an appropriate message is output to the outside world, without having to explicitly know all the possible operational situations even in the development phase of the power supply unit.
