Abstract
Abstract Water which is to be mixed with hydrocarbon fuel for feedstock in a hydrogen generator has low pressure hydrogen diffused therein so as to permit a hydrogen rich fuel-water admixture to enhance desulfurization of the admixture, without fuel sulfur poisoning of a diffuser. The hydrogen is fed back serially or in parallel from any point downstream of a steam reforming reactor.
