Abstract This work investigates the long-term performance of Ba-Ni-hexaaluminate, BaNi x Al 12− x O 19 as a catalyst in reforming of 1-methyl naphthalene and/or methane in a model-gas simulating that from a circulating fluidized bed (CFB) gasifier during 23–29 h in a lab scale set-up, as well as the tendency for coke formation, sintering and sulphur poisoning. 1-Methyl naphthalene is used as a tar model substance. The Ba-Ni-hexaaluminate induces a high conversion of both compounds in the temperatures investigated (850 and 950 °C) under sulphur-free conditions. In sulphur-containing gas, the methane conversion stops at 20 ppm H 2 S and the reforming of 1-MNP at 850 °C is slightly reduced at 100 ppm. Graphic Abstract

Ba-Ni-六铝酸盐作为1-甲基萘和甲烷蒸汽重整的新型催化剂

摘要 本工作研究了 Ba-Ni-六铝酸盐 BaNi x Al 12- x O 19 作为催化剂在模拟来自循环流化床的模型气体中重整 1-甲基萘和/或甲烷的长期性能。 (CFB) 气化炉在实验室规模设置中的 23-29 小时，以及焦炭形成、烧结和硫中毒的趋势。1-甲基萘用作焦油模型物质。Ba-Ni-六铝酸盐在无硫条件下在所研究的温度（850 和 950 °C）下诱导两种化合物的高转化率。在含硫气体中，甲烷转化在 20 ppm H 2 S 时停止，1-MNP 在 850 °C 时的重整在 100 ppm 时略有减少。图形摘要
