Verfahren und Apparatur zur Dampfreformierung von Kohlenwasserstoffen

摘要

In a process for the catalytic steam reforming of fluid hydrocarbons, a hydrocarbon fuel is combusted in a chamber 6 with compressed air in an amount exceeding that required for complete combustion and the hot gases are expanded in a turbine 9 passed via a waste-heat boiler 14 and line 16 to a furnace 19 containing tubes 24 filled with catalyst and through which a mixture of steam and hydrocarbons for reforming is being passed, additional hydrocarbon fuel being added to the hot gases from line 16 to be combusted in the furnace for external heating of the catalyst tubes. The stream of steam and fluid hydrocarbons being reformed may be heated to between 600 DEG and 1500 DEG F. and the carbon monoxide in the produced gas may be reacted with further steam in known manner. The turbine 9 drives an air compressor 2 and a compressor 13 for compressing the product gas.
