Japanese Patent JPH0817946

Kind Code:

B2

Abstract:

Normal paraffin hydrocarbons are isomerized to produce products containing non-normal hydrocarbons using a novel zeolite beta catalyst that has been activated in order to enhance its catalytic properties by treating at an activation temperature effective to substantially reduce the concentration of strong acid species, i.e., hydronium cations, without substantially reducing the concentration of weak acid species, i.e., hydroxoaluminum cations, both of said strong acid species and weak acid species being initially present on the catalyst prior to activation. The isomerization step is preferably thereafter conducted at a temperature at least 300 DEG C lower than the activation temperature.
