Abstract

Abstract: Catalytic dehydrogenation of low-carbon alkane to high-value olefin is a high-efficient way of utilizing petrochemical resources. In this study,the fluidization performance of the catalyst PBD was investigated in terms of particle density, size distribution, and minimum fluidization velocity. The findings indicated that the catalyst PBD with appropriate particle size distribution and density belongs to Geldart A particles which can be readily fluidized. Additionally,the abrasion rate of the catalyst PBD was 0.27%, only 1/8 to 1/4 of that of catalyst R and W, which means a dramatic reduction in catalyst consumption in industrial plants.

Key words: low-carbon alkane, dehydrogenation, catalyst, circulating fluidized bed, attrition

摘要： 将相对廉价的低碳烷烃经催化脱氢转变成高附加值的烯烃，并副产大量氢气，是石化资源高效转化与利用的有效途径。本研究针对自主研发的PBD型低碳烷烃脱氢催化剂，分别从催化剂密度、粒径分布及最小流化速度等多个方面进行了流化特性研究。结果表明，PBD型催化剂具有适宜的粒径分布与颗粒密度，属于Geldart A类颗粒，完全适用于循环流化床脱氢装置。此外，PBD型催化剂的磨耗率仅0.27%，是国内同类型催化剂磨耗率的1/8~1/4，可有望大幅度减少工业装置中催化剂的消耗量。
