ABSTRACT:
A novel synthesis composition of a solid acid containing zirconium, in addition to a rare earth element, such as cerium, has the potential for catalytic conversions of hydrocarbons, especially for isomerization of paraffins, ring opening of cyclics, hydrocracking, alkylation, hydrogenation of polynuclear aromatics, selective catalytic reduction of nitrogen oxides, and oligomerization of light olefins.
