Methods and systems for hydrocracking a heavy oil feedstock include using a colloidal or molecular catalyst (e.g., molybdenum sulfide) and provide for concentration of the colloidal or molecular catalyst within the lower quality materials requiring additional hydrocracking in one or more downstream reactors. In addition to increased catalyst concentration, the inventive systems and methods provide increased reactor throughput, increased reaction rate, and of course higher conversion of asphaltenes and lower quality materials. Increased conversion levels ...
1. A method of hydrocracking a heavy oil feedstock using a colloidal or molecular catalyst, comprising: introducing an entirety of a heavy oil feedstock including a colloidal or molecular catalyst and/or catalyst precursor into a first hydrocracking reactor, the first hydrocracking reactor having a first concentration of colloidal or molecular catalyst and producing an effluent;separating the effluent produced by the first hydrocracking reactor into a lower boiling vapor fraction and a higher boiling liquid fraction, the higher boiling liquid fraction in...
