Abstract
A process for preparing a catalyst, the catalyst itself, and a process for using the catalyst are disclosed generally for the conversion of hydrocarbons. By the use of at least one high temperature calcination under substantially dry conditions, a catalyst with a beneficial combination of lowered surface area and excellent piece crush is created. X-ray diffraction pattern information is used to distinguish the resulting product.
