Abstract
A process for hydroprocessing a hydrocarbonaceous feedstock in a continuous liquid phase utilizes a hydroprocessing catalyst comprising pills that have a largest dimension that averages no more than 1.27 mm ( 1/20 inch) and more than 100 nm to produce a hydrocarbonaceous product stream.
Claims19
A process for hydroprocessing a hydrocarbonaceous feedstock which comprises:
- introducing a liquid phase stream comprising a hydrocarbonaceous feedstock and a sufficiently low hydrogen concentration to maintain a continuous liquid phase into a hydroprocessing reactor containing hydroprocessing catalyst comprising pills that have a largest dimension that averages no more than 1.27 mm ( 1/20 inch) and more than 100 nm to produce a first hydrocarbonaceous product stream.
A process for hydroprocessing a hydrocarbonaceous feedstock which comprises:
- introducing a liquid phase stream comprising a hydrocarbonaceous feedstock and a sufficiently low hydrogen concentration to maintain a continuous liquid phase into a hydroprocessing reactor containing hydroprocessing catalyst comprising pills that have a largest dimension that averages no more than 0.85 mm ( 1/30 inch) and no less than 0.51 mm ( 1/50 inch).
A process for hydroprocessing a hydrocarbonaceous feedstock which comprises:
- introducing a stream comprising a hydrocarbonaceous feedstock and hydrogen into a hydroprocessing reactor containing a fixed bed of hydroprocessing catalyst comprising pills having a largest dimension that averages no more than 0.51 mm ( 1/50 inch).
