Coprecipitated Chromia-Alumina Catalysts for Naphtha Reforming with Hydrogen

Cogelled Chromia-Alumina Catalyst for Naphtha Reforming. Evaluation of Hydrocarbon Types and Naphthas.

“…reforming of petroleum naphthas is increasing in importance as a process to provide gasoline of high octane number, aromatic concentrates for aviation gasoline, and pure aromatics. The first paper of this series (8) showed that a coprecipitated catalyst composed of chromia and alumina was of unusual interest for this purpose. One outstanding characteristic of the catalyst was that it enabled the coke deposition on the catalyst to be controlled to a low level by a lower partial pressure of hydrogen than is used with any other catalyst.…”
