In this article, the bifunctional NiO/CaO@C12A7 catalysts having reforming catalytic effect and CO₂ adsorption effect were prepared with co‐precipitation method, and were used in the sorption‐enhanced steam reforming process of tar from RCOG for hydrogen production. Among six kinds of samples with different load ratios, the catalyst with the CaO:C12A7:NiO ratio of 70:15:15 showed the best catalytic performance for the steam reforming of tar to produce H₂ as well as the excellent characterization. Under the action of this catalyst, the H₂ yield obtained from the steam reforming process of 1‐methylnaphthalene (C₁₁H₁₀) as the tar model compound were higher than that from the common steam reforming process, and the best H₂ yield was obtained at the reforming temperature of 750°C, the S/C ratio of 12 and the WHSV of 0.055 hr⁻¹, with the value of 83.9%.

在双功能催化剂上，将焦炉煤气中的焦油进行蒸汽重整：H2生产的重整性能

本文采用共沉淀法制备了具有重整催化作用和CO ₂吸附作用的双功能NiO / CaO @ C12A7催化剂，并将其用于RCOG焦油的吸附增强蒸汽重整过程中，用于制氢。在六种负载比不同的样品中，CaO：C12A7：NiO比为70:15:15的催化剂对焦油蒸汽重整生成H ₂表现出最佳的催化性能，并具有出色的表征。在这种催化剂的作用，将H ₂从1-甲基萘（C的蒸汽重整方法得到的产率₁₁ ħ ₁₀）作为焦油模型化合物要高于普通蒸汽重整工艺，并且在750°C的重整温度，12的S / C比和0.055 hr ^-1的WHSV下获得了最佳的H ₂收率，价值为83.9％。
