Abstract
The invention provides a process for operating a system for water vapor reforming of methanol in which, in a mixture preparation step, a water vapor/methanol mixture is prepared from water and methanol and is introduced into a reforming reactor. According to the invention, the mixing ratio of the water vapor/methanol mixture is adjusted as a function of the load condition and/or load changes of the system so that a CO-concentration is obtained in the reformate which remains constant over the whole load range.
