    摘要: A process for the production of propylene, the process including: fractionating a hydrocarbon stream comprising n-butenes, isobutylene, and paraffins into at least two fractions including a light C4 fraction comprising isobutylene and a heavy C4 fraction comprising n-butenes and paraffins; contacting at least a portion of the heavy C4 fraction with a metathesis catalyst to form a metathesis product comprising ethylene, propylene, C4+ olefins, and paraffins; fractionating the metathesis product into at least four fractions including an ethylene fraction, a propylene fraction, a C4 fraction comprising C4 olefins and paraffins, and a C5+ fraction; cracking the light C4 fraction and the C5+ fraction to produce a cracking product comprising ethylene, propylene, and heavier hydrocarbons; and fractionating the cracking product into at least two fractions including a light fraction comprising propylene and a fraction comprising C5 to C6 hydrocarbons.

    摘要: Extruded isomerization catalysts comprising MgO, a metal silicate clay binder and a stabilizer and methods of forming such isomerization catalysts are disclosed. Also disclosed are isomerization catalysts that exhibit a fresh isomerization rate and an aged isomerization rate that is at least 50% of the fresh isomerization rate. Embodiments of the isomerization catalysts disclosed herein include metal silicate clay binders that include a layered structure and metal silicate. The metal silicate clay binder may be present in an amount in the range from about 5 wt% to about 20 wt%. Exemplaiy stabilizers include one or more of Zr02, tetravalent rare earth metal and a trivalent rare earth metal. Stabilizers may be present in an amount up to about 40 \vt%. One or more improved properties, such as piece crush strength and isomerization performance, are exhibited by the catalyst article.
