Simultaneous upgrading and dedusting of liquid hydrocarbon feedstocks
This patent describes a process for simultaneously upgrading and dedusting liquid hydrocarbon feedstocks. It comprises injecting dust particulate-containing raw retort effluent product stream from a feed line into a catalytic hydrotreater capable of agitating the product stream during hydrotreatment; agitating the product stream with a hydrotreating gas upstream of the hydrotreater to substantially prevent settling of particulate matter in the feed line; agglomerating the particulates to enhance solid-liquid separation and removing at least 90% of sulfur and nitrogen contaminants to produce synthetic crude oil by hydrotreating the product stream in the presence of a hydroprocessing catalyst at a temperature of from about 760{degrees} to about 825{degrees}F, under a hydroprocessing gas pressure of from about 1500 to about 2500 psi and at a space velocity of from about 0.1 to about 6.0 hr{sup -1}; and substantially separating the agglomerated particulates from the hydrotreated oil.
