Process for heavy oil feedstock hydrocracking using colloidally dispersed or molecularly dispersed catalysts (eg, molybdenum sulfide, etc.) resulting in the concentration of colloidally dispersed catalysts in low quality materials that require additional hydrocracking and Provide a system. In addition to increasing catalyst concentration, the systems and methods of the present invention result in increased reactor throughput, increased reaction rates, and, of course, increased conversion of asphaltenes and lower quality materials. Increasing the level of conversion of asphaltenes and low quality materials also reduces equipment contamination and allows the reactor to process a wider range of low quality feedstocks, and such catalysts are used in conjunction with colloidal or molecular catalysts. In this case, the supported catalyst may be used more efficiently. |
