PURPOSE: A process for catalytic autothermal steam reforming of alcohols, which have two or more carbon atoms, by directing a preheated educt or reactant mixture of alcohols, oxygen and water or steam over a catalyst is provided. CONSTITUTION: In a process for catalytic autothermal steam reforming of alcohols having two or more carbon atoms comprising directing a preheated reactant mixture of the alcohols, oxygen and water or steam over a catalyst, the process for catalytic autothermal steam reforming of alcohols is characterized in that it is conducted in an adiabatic manner, wherein the catalyst comprises at least one platinum group metal on an oxidic support selected from the group consisting of aluminum oxide, silicon dioxide, titanium dioxide or mixed oxides thereof and zeolites, wherein the reactant mixture contains additional hydrocarbons, which are reformed at the same time as the alcohols, wherein the preheated reactant mixture comprises about 0.5 to about 10 wt.% hydrocarbons, based on the total weight of alcohols and hydrocarbons, and wherein the catalyst additionally comprises at least one oxide selected from the group consisting of boric oxide, bismuth oxide, gallium oxide, alkali metal oxides, alkaline earth metal oxides, oxides of subgroup elements and rare earth metal oxides in a concentration of up to about 40 wt.% based on the total weight of the catalyst composition. |
