Scientists from the University of Illinois at Urbana-Champaign (edlinks.che.com/6517-551) have developed a catalyst that uses hydrogen to efficiently destroy harmful perchlorate in contaminated groundwater. The catalyst is composed of palladium and rhenium supported on activated carbon. The rhenium removes an oxygen atom from the perchlorate...

Professor Yasutaka Ishii, and colleagues from the Dept. of Applied Chemistry, Kansai University (Osaka, Japan; edlinks.che.com/5830-535), has developed a three-step production process to make epsilon-caprolactam (CPL) from cyclohexane. Compared to alternative methods, the process has a higher CPL yield, generates less waste, and avoids the use of corrosive reagents, says Ishii. The convectional route to...

    Advances in catalytic cracking technologies are improving efficiency, product selectivity and environmental emissions. Optimum performance, reliability and flexibility of fluid catalytic cracking (FCC) units is essential for the continued competitiveness of refineries and their ability to meet market demands for refined products. FCC traditionally converts gas oil and heavier residual oil to...

    Liquids are accumulated and stored in tanks of various shapes and sizes throughout the chemical process industries (CPI). A small number of companies have made the design, fabrication and erection of these vessels their specialty. Initially, however, it is the process engineer who sizes and specifies tanks according to a specific application’s needs. In order to develop a data sheet for...

Haldor Topsøe (Lyngby, Denmark; edlinks.che.com/5826-533) has introduced two new hydroprocessing catalysts, which are based on its proprietary BRIM technology. Both catalysts are nickel-molybdenum types that optimize both hydrogenation at so-called brim sites (situated on the basal-plane of the catalyst) and the Type II active sites (edge sites) for direct...
