Tubular heater for cracking hydrocarbons

摘要

A reactor for reacting hydrocarbons with steam to produce carbon monoxide and hydrogen containing gases in the presence of a catalyst contained in a reaction tube and indirectly heated by heating fluid which is a gas that has been used to cool a nuclear reactor. The reaction tubes are surrounded by the heating fluid over a portion of their length in a heating zone and the other portion thereof is positioned outside of the heating zone. The reaction tubes are provided with one or more conduits for feeding of reactants and one or more conduits for discharging product gas.
