制备了具有相同氢／长链烷烃分离系数和不同氢气渗透率及具有相同氢气渗透率和不同氢／长链烷烃分离系数两个系列的多孔膜管，考察了反应温度、氢／烃比、吹扫气流速、膜的分离系数和渗透率对长链烷烃（Ｃ１１～Ｃ１３）脱氢反应的影响．结果表明，不同温度和氢烃比条件下，膜反应器中转化率均高于固定床中转化率，实验范围内增大吹扫气流速会提高转化率，其变化规律与丙烷脱氢类似；转化率随膜分离系数和渗透率的增加而增大，但增大到一定程度后则几乎不再增大，其分界大致在氢／烃分离系数为１０，氢气渗透率为１５×１０－７ｍｏｌ／（ｍ２·ｓ·Ｐａ），显示出适合此反应的膜的制备较为容易．
Two series of porous membrane tubes with the same hydrogen / long chain paraffin separation factor, different hydrogen permeability and the same hydrogen permeation rate and different hydrogen / long paraffin separation coefficients were prepared. The influences of reaction temperature, hydrogen / hydrocarbon ratio, Effect of scavenging velocity, membrane separation factor and permeability on dehydrogenation of long-chain alkanes (C11 ~ C13). The results showed that the conversions of the membrane reactor were higher than those of the fixed bed reactor under different temperature and hydrogen-to-hydrocarbon ratios. Increasing the flow rate of the purge gas within the experimental range increased the conversion rate, which was similar to that of propane dehydrogenation. The rate increases with the increase of membrane separation factor and permeability, but increases to a certain extent, then almost does not increase, the boundary is roughly in the hydrogen / hydrocarbon separation factor of 10, the hydrogen permeability of 15 × 10-7mol / (M2 · s · Pa), which shows that the preparation of the membrane suitable for this reaction is relatively easy.
