A PROCESS FOR PREPARING A FUEL FOR AUTOMOTIVE APPLICATIONS, STATIONARY ENGINES AND MARINE APPLICATIONS BY CATALYTIC LIQUID PHASE ALCOHOL CONVERSION AND A COMPACT DEVICE FOR CARRYING OUT THE PROCESS.

摘要

A fuel for automotive applications and marine applications is prepared by catalytic liquid phase conversion of the alcohol (s) of an alcohol-containing primary fuel to the corresponding ether (s) in a compact device comprising an inlet for an alcohol-containing fuel from the primary tank, a start-up heater, a heat exchanger, which heats up the cold alcohol (s) to a suitable temperature before entering the reactor, a catalytic bed within the reactor, wherein the alcohol(s) is/are partly converted to ether(s), a pressure reduction valve, inlet means for adding additives and a buffer tank, wherein the resulting fuel mixture of alcohol (s) and ether (s) is stored after passing back through the heat exchanger for suitable cooling, the heater only being used during start-up and the process thereby being conducted under auto-thermal operation conditions.
