Title:
Boiling bed process for raw materials containing dissolved hydrogen
Document Type and Number:
Japanese Patent JP6336538
Kind Code:
B2
Abstract:
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.
