考察了通过钯渗透膜提供的氢原子对噻吩加氢脱硫的反应活性，并与气相解离吸附提供的氢原子在钯膜上的反应活性进行了比较。与氢原子与噻吩膜表面共吸附的体系相比，氢原子渗入钯的体系具有更高的脱硫活性。在氢渗透系统中，吸附在膜表面的噻吩烯分子被氢原子氢化，氢原子不仅通过膜表面供应，而且从膜的本体供应。
The reactivity of hydrogen atoms supplied by permeating through a palladium membrane was investigated for hydrodesulfurization of thiophene by comparison with that of hydrogen atoms supplied by dissociatively adsorbing on the palladium membrane from the gas phase. A system with hydrogen atoms permeating through the palladium bulk gave higher desulfurization activities as compared to a system with hydrogen atoms co-adsorbing with thiophene molecules on the membrane surface. With the hydrogen permeating system, thiophene molecules adsorbed on the surface were hydrogenated by hydrogen atoms supplied not only through the surface but also from the bulk of the membrane.
