Catalyst used in refinery and petrochemical plants for hydrogenating hydrocarbon streams in gas or liquid phase comprises hydrogenation-active metal on aluminum oxide support

摘要

Catalyst comprises a hydrogenation-active metal on an aluminum oxide support and has a specified X-ray diffractogram. Catalyst comprises a hydrogenation-active metal on an aluminum oxide support and has the following specified X-ray diffractogram: planar distance d (10<-10> m) to relative intensity I/Io: 4.52: 0.05-0.1; 2.85: 0.35-0.45; 2.73: 0.65-0.8; 2.44: 0.45-0.55; 2.31: 0.35-0.45; 2.26: 0.35-0.45; 2.02: 0.45-0.6; 1.91: 0.3-0.4; 1.80: 0.1-0.25; 1.54: 0.25-0.35; 1.51: 0-0.35; 1.49: 0.2-0.3; 1.45: 0.25-0.3; 1.39: 1. The metal is a group 8, 9 or 10 metal, preferably Pt or Pd. The catalyst may also contain a group 11 metal, preferably Cu and/or Ag. An Independent claim is also included for the production of the catalyst comprising treating an Al-containing raw material with water, dilute acid or base, forming a molded body, drying, calcining at 900-1100 deg C, impregnating with a solution containing the metal to be deposited, drying and finishing the molded body.
