In this study, we constructed a palladium membrane reactor and investigate the reaction of hydrogen permeated through membrane, which is expected to have a unique feature as a reagent, for the elimination of hetero-atoms from petroleum fractions.(1) The membrane reactor : The reactor consisted of two knife-edge flanges between which a thin palladium membrane, 0.05 mm thick, was put with a copper gasket. The membrane divided the reactor into two parts. By introducing hydrogen in one part and the reactant in other part, the reaction of hydrogen atoms supplied by permeating through the palladium membrane (permeated hydrogen) was followed.(2) The reactivity of permeated hydrogen : The reactivity of permeated hydrogen was compared with those supplied by mixing with the reactants (adsorbed hydrogen). The permeated hydrogen showed an activity higher than that of the adsorbed hydrogen for hydrogenation of pyridine and hydrodesulfurization of thiophene. The difference was more marked at higher pressures of hydrogen. The activation energies of hydrodesulfurization of thiophene in a temperature range of 573-673 K were 32 and 42 kcal/mol for permeated and adsorbed hydrogen, respectively. These results suggest that the hydrogen atoms supplied through the membrane are in a state different from those adsorbed by normal manner.

在这项研究中，我们构建了一个钯膜反应器，并研究了氢通过膜的反应，这是一个独特的功能，作为一种试剂，从石油馏分中消除杂原子。(1)膜反应器：该反应器由两个刀口凸缘组成，在两个刀口凸缘之间放置0.05 mm厚的薄钯膜，并带有铜垫圈。膜将反应器分成两部分。通过在一部分中引入氢和在另一部分中引入反应物，进行通过渗透通过钯膜提供的氢原子（渗透氢）的反应。(2)渗透氢的反应性：将渗透氢的反应性与通过与反应物（吸附氢）混合提供的反应性进行比较。渗透氢对吡啶加氢和噻吩加氢脱硫的活性高于吸附氢。在较高的氢气压力下，这种差异更为显著。在573-673 K温度范围内，噻吩加氢脱硫反应的活化能分别为32和42 kcal/mol。这些结果表明，通过膜供应的氢原子处于与正常方式吸附的氢原子不同的状态。
