Abstract
This paper presents the performance and characteristics of new-type sulfur tolerant shift catalyst QDB-04 and its industrial side-line test as well as the first-time industrial application in Lunan Chemical Fertilizer Plant of Shandong in China. The results show that the catalyst has high strength and strength stability, good low temperature activity and stability as well as low potassium bleeding ratio which well meet for the requirements of the methanol plant on catalyst performance in Lunan Chemical Fertilizer Plant.
Highlights
Great attentions have been paid to the sulfur tolerant shift catalyst because of its excellent shift activity, sulfur tolerant ability and poisoning resistance
This paper presents the performance, characteristics and first-time industrial application of the new-type sulfur tolerant shift catalyst QDB-04 in Lunan Chemical Fertilizer Plant of Shandong in China
Whether fresh sample or the ones applied in industrial plant, the strength retention ratio of QDB-04 keeps well above 90% which shows very good strength stability
Summary
Great attentions have been paid to the sulfur tolerant shift catalyst because of its excellent shift activity, sulfur tolerant ability and poisoning resistance. Many brands of such catalyst have been developed in the world, for example, K8-11 of BASF in Germany, SSK of TOPSOE in Denmark and QDB series of Qindao Lianxin Catalytic Materials Co., Ltd [1] [2]. MgAl2O4based catalyst has better strength and stability which can be applied in large-scale ammonia plant with high pressure, high water/gas ratio [3] [4]. These kinds of catalysts have complicated production process and high price. The catalyst has simple production process, low price, high low-temperature activity, but its strength and
