Abstract
Official abstract text for this publication.
An improved system and method for processing feedstocks in an ebullated-bed hydroprocessing reactor is provided in which hydrogen gas is dissolved in the fresh and recycled liquid feedstock by mixing and/or diffusion of an excess of hydrogen, followed by flashing of the undissolved hydrogen upstream of the reactor inlet, introduction of the feed containing dissolved hydrogen into the ebullated-bed hydroprocessing reactor whereby the dissolved hydrogen eliminates or minimizes the prior art problems of gas hold-up and reduced operational efficiency of the recycle pump due to the presence of excess gas in the recycle stream when hydrogen gas was introduced as a separate phase into the reactor.
First claim
Opening claim text (preview).
1 - 22 . (canceled) 23 . A process for the conversion of a liquid hydrocarbon feedstock into lower molecular weight hydrocarbon compounds in an ebullated-bed catalytic hydroprocessing reactor, the reactor including a product outlet in fluid communication with a substantially catalyst-free region above the ebullated catalyst bed for transferring ebullated bed reactor effluents that include unreacted or partially reacted hydrocarbons, the process comprising: mixing the liqui…
