BenchCAT-HTS was developed for secondary catalyst screening in a combinatorial program and has been placed in most of the major oil and chemical companies.  BenchCAT-HTS is also favored as a primary screening device by universities and a number of automotive companies. BenchCAT-HTS is available as a stand-alone reactor device, designed to be retrofitted into existing bench-scale reactor systems, or as part of a comprehensive, ready-to-run, fully automated reactor system, driven by high performance LabVIEW software. BenchCAT-HTS has a single, high pressure closure, and is customizable, as to metallurgy, design pressure and temperature, reactor well volume, and flows.
