Manufacturing of raw materials for the catalyst industry

摘要: Abstract As known from modern catalytic surface science the nature and quality of carrier material is a key part catalysis. Defined properties consistent are pre-requisites for successful catalyst. This paper will demonstrate possibilities flexibility CONDES's alkoxide technology in terms manufacturing aluminas, silica-aluminas other mixed oxides as raw materials catalyst industry. The CONDEA group operates two different types processes manufacture derived alumians related products, Ziegler-ALFOL process CONDEA's On-Purpose Process. Ziegler co-production linear fatty alcohols alumina, using aluminum organic compounds intermediates, own On- Purpose based on formation metal alcohol. In both alumina achieved by hydrolysis alcoholates with water.AI(OR) 3 + 2 H 0 → A1OOH ROH Alumina typically obtained form boehmite or pseudoboehmite. It important to mention that give products equivalent quality. Subsequent processing steps lead variety high purity defined physical such as. • beohmite aluminas crystallite size, porosity, particle size peptisation dispersion behavior calcined phase compositions (gamma, delta/theta, alpha), porosities, areas, sizes attrition resistance. Besides phases bayerite eta can also be produced via this technology. Also accessible an almost unlimited silica doped aluminas. Even example, MgO obtained. A concept product development controlled scale-up new laboratory commercial production. gap between pilot production full scale production, typical industry, being bridged flexible multi-purpose semi-commercial unit approx. 1200 mt per year capacity, where large samples manufactured during developmental stage. reduces factors reasonable ratio helps shorten applications.
