| 1 | Comparative study of fluidized-bed and fixed-bed reactor for syngas methanation over Ni-W/TiO_2-SiO_2 catalyst显示文摘In this work,syngas methanation over Ni-W/TiO2-SiO2catalyst was studied in a fluidized-bed reactor(FBR)and its performance was compared with a fixed-bed reactor(FIXBR).The effects of main operating variables including feedstock gases space velocity,coke content,bed temperature and sulfur-tolerant stability of 100 h life were investigated.The structure of the catalysts was characterized by XRD,N2adsorptiondesorption and TEM.It is found that under same space velocity from 5000 h 1to 25000 h 1FBR gave a higher CH4yield,lower coke content,and lower bed temperature than those obtained in FIXBR.Ni-W/TiO2-SiO2catalyst possessed excellent sulfur-tolerant stability on the feedstock gases less than 500 ppm H2S in FBR.The carbon deposits formed on the spent catalyst were in the form of carbon fibers in FBR,while in the form of dense accumulation distribution appearance in FIXBR. | Bo Liu Shengfu Ji | 2013 | Journal of Energy Chemistry2013，22，5： | 6 |
| 2 | 合成气制甲醇催化剂研究进展Ⅱ——其它催化剂显示文摘甲醇是最基本的有机化工原料之一,工业规模的甲醇一般是用含有氢气、一氧化碳和二氧化碳的合成气在一定压力和温度并有催化剂存在的条件下反应的方法生产,而甲醇工业的发展,很大程度上取决于催化剂的研制成功及其性能改进,目前主要采用金属催化剂,尤其是铜基催化剂。本文对合成气制甲醇中所使用的除铜基催化剂以外的其它金属催化剂进行了综述。 | 陈文瑞 冯媛 李虎强 | 2017 | 广州化工2017，45，10： | 1 |
