摘要:
The invention relates to a process for the production of thermally-integrated hydrogen from a liquid hydrocarbon feedstock that contains sulfur-containing compounds that comprise at least one stage for heating the liquid hydrocarbon feedstock by indirect heat exchange with a hot stream, a stage for desulfurizing the heated hydrocarbon feedstock, a stage for evaporating the desulfurized hydrocarbon feedstock by indirect heat exchange with the hot stream that exits from the autothermal reformer, a stage for autothermal reforming of the hydrocarbon feedstock, and a stage wherein the carbon monoxide content in the hydrogen-rich gas that is produced is reduced in a reactor for converting carbon monoxide with water. The invention also relates to the hydrogen production installation that corresponds to this process.

摘要:
Hydrogen generators operating over a range of hydrogen production rates are controlled by alternating production between a net hydrogen make rate and a net hydrogen loss rate. A hydrogen reservoir (150) is provided and the amount of hydrogen in the reservoir is the determinant as to which hydrogen production rate is employed by the hydrogen generator.
摘要:
Apparatus and processes for the generation of hydrogen from hydrocarbon feeds are provided in which organosulfur compound is removed from the feed. The apparatus and processes are particularly advantageous as smaller scale hydrogen generators including those generators intended for residential use to produce hydrogen for fuel cells to produce electricity. In the processes and apparatus, the feed is contacted with solid sorbent to remove organosulfur compound.
