Abstract: The invention relates to a method and a device for reforming diesel fuel into a product gas containing H2 and CO, the diesel fuel being mixed in a first premixing stage with an O2-containing gas mixture and subsequently the thus obtained mixture being mixed in a second premixing stage with an O2-containing gas mixture and also with an exhaust gas mixture and subsequently this mixture being subjected to a hydrocarbon oxidation in a reactor with a catalyst.

Abstract: In a process for the catalytic NOx reduction in oxygen-containing exhaust gases of a thermal engine in one or several reduction catalytic converters, hydrocarbons of the fuel of the thermal engine are used in the reduction catalytic converter(s). In order to avoid toxic or dangerous substances and gases, respectively, during said NOx reduction, the process is characterized by the use of a gas mixture as a reducing agent for the reduction catalytic converter(s), which gas mixture is produced in a controlled manner from the fuel of the thermal engine in a catalytic reformer and/or in a fuel cell.

Abstract: The invention relates to a process and device for the recovery of energy from the waste heat of thermal or chemical processes, wherein at least a portion of said waste heat evaporates a liquid via at least one heat transfer means or heats a vapour or a gas, increasing the pressure thereof, and this pressure is transformed into mechanical energy in an engine (FIG. 1).
