Verfahren zur Herstellung eines Cr/Ni-Traegerkatalysators fuer selektive Hydrierung von Diolefinen und Acetylenkohlenwasserstoffen

摘要

Diolefins and/or acetylene hydrocarbons contained in a charge of olefin hydrocarbons are selectively hydrogenated in the presence of a catalyst containing nickel and chromium uniformly distributed on a refractory oxide such that the catalyst contains from 0.02 to 0.2 mgm./m2., and the other hydrogenation conditions being: Temperature 100 DEG to 300 DEG C. Pressure 50 to 70 atmospheres. Space velocity 500 to 520 v./v./hr.ALSO:Chromium and nickel are deposited on a refractory oxide support such that the resulting catalyst contains 0.02 to 0.2ngm/sq. m. Specified supports are a -Al203, SiO2 or SiO2-Al203. Impregnation of the support is preferably offected by use of Ni Cr207 solution. The catalyst may have a surface area of 343 sq. m/gm. and be shaped as desired.
