The objective of this study is to develop ceramic supports employed in the preparation of catalytic membrane reactor using less catalyst and lower temperature and enabling H₂ production and separation together through the dry reforming of methane. For this reason, nine different ceramic supports are fabricated by using three different types of activated alumina (acidic, basic and neutral) and three different Si/Al molar ratios at two different calcination temperatures in order to investigate the surface acidity and basicity effect of supports to be used with impregnated Rh catalyst for rising the activity to CH₄, CO₂ and sensitivity to coke formation encountered with Ni-based catalysts. Subsequently, the effect of those variations on supports is determined by using XRD, SEM and BET instruments, in addition to this, H₂ permeability test of five supports having high BET surface areas is also performed with using constant volume-variable pressure technique at the temperatures of between 25 and 250 °C. Acidic alumina sintered at 600 °C and containing Si/Al ratio of 0.648 represented the highest hydrogen permeability with higher activity, whereas, neutral alumina calcined at the temperature of 600 °C having Si/Al ratio of 0.555 gave the highest activity with the lower hydrogen permeability, while basic alumina sintered at the temperature of 600 °C and including Si/Al ratio of 0.648 imparted lower activity with higher hydrogen permeability.

本研究的目的是开发用于制备催化膜反应器的陶瓷载体，使用较少的催化剂和较低的温度，并通过甲烷的干重整实现 H _{2 的}生产和分离。为此，通过使用三种不同类型的活性氧化铝（酸性、碱性和中性）和三种不同的 Si/Al 摩尔比在两种不同的煅烧温度下制造了九种不同的陶瓷载体，以研究载体的表面酸性和碱性影响与浸渍的 Rh 催化剂配合使用，提高对 CH ₄ , CO ₂的活性和镍基催化剂遇到的焦炭形成的敏感性。随后，这些变化对载体的影响通过使用 XRD、SEM 和 BET 仪器确定，除此之外，H ₂还使用恒定体积变压技术在 25 至 250 °C 的温度下对具有高 BET 表面积的五种载体进行渗透性测试。酸性氧化铝在 600°C 烧结且含有 0.648 的 Si/Al 比代表最高的氢渗透率和较高的活性，而在 600°C 的温度下煅烧，Si/Al 比为 0.555 的中性氧化铝具有最高的活性，但活性较低。氢渗透率，而碱性氧化铝在 600 °C 的温度下烧结并且包含 0.648 的 Si/Al 比赋予较低的活性和更高的氢渗透率。
