Abstract
Abstract An apparatus for rapidly testing catalyst samples wherein a vertical reactor surrounded by a heat transfer medium and containing a removable catalyst support is arranged for loading catalyst through the reactor top and for its removal through the bottom after testing. A preheater section is provided for preheating the reactant feed stream. It interconnects with the reactor between the catalyst inlet and outlet ports.
