| 摘要 |
<p>A process is provided for converting feedstock hydrocarbon compounds to product hydrocarbon compounds having a lower molecular weight than feedstock hydrocarbon compounds over a catalyst composition which comprises MCM-58 or a mixture of MCM-58 and another, e.g., intermediate- or large-pore, molecular sieve component. An embodiment of the present invention comprises an improved catalytic cracking process to produce high octane gasoline and lower molecular weight olefins, e.g. propylene.</p> |
