Benefits of technology

[0009]We have found that integration of SHC and hydrotreating with FCC results in improved performance of all three processes. Heavy VGO from the SHC reactor and/or main column bottoms from the FCC unit are combined with the feed to the SHC unit. All lighter products of the SHC are processed in a hydrotreater. The hydrotreater process conditions and catalyst type are chosen so that the light VGO product from the SHC unit is hydrogenated, desulfurize

Problems solved by technology

These heavy hydrocarbon feedstocks may be characterized by low reactivity in visbreaking, high coking tendency, poor conversion in hydrocracking and difficulties in distillation.
They may have, in general, a low ratio of polar aromatics to asphaltenes and poor reactivity in a hydrocracking environment relative to aromatic feedstocks.
However, since this product VGO is hydrogen-deficient and high in sulfur and nitrogen contaminants it must be further hydroprocessed, cracked and/or reformed in order to produce useful transportation fuels.
However, a number of problems must be solved for the FCC unit to perform well with this type of feedstock.

Embodiment Construction

[0013]The process and apparatus of this invention is capable of processing a wide range of heavy hydrocarbon feedstocks. It can process aromatic feedstocks, as well as feedstocks which have traditionally been very difficult to hydroprocess, e.g. vacuum bottoms, visbroken vacuum residue, deasphalted bottom materials, off-specification asphalt, sediment from the bottom of oil storage tanks, etc. Suitable feeds include atmospheric residue boiling at about 650° F. (343° C.), heavy vacuum gas oil (VGO) and vacuum residue boiling at about 800° F. (426° C.) and vacuum residue boiling above about 950° F. (510° C.). Throughout this specification, the boiling temperatures are understood to be the atmospheric equivalent boiling point (AEBP) as calculated from the observed boiling temperature and the distillation pressure, for example using the equations furnished in ASTM method D1160. Furthermore, the term “pitch” is understood to refer vacuum residue, or material having an AEBP of greater tha...

Abstract

A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked to produce vacuum gas oil (VGO). A light portion of the VGO may be hydrotreated and subjected to fluid catalytic cracking to produce fuels such as gasoline. A heavy portion of the VGO may be recycled to the slurry hydrocracking reactor. FCC slurry oil may be recycled to the slurry for hydrocracking.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to a process and apparatus for the treatment of crude oils and, more particularly, to the hydroconversion of heavy hydrocarbons in the presence of additives and catalysts to provide useable products and further prepare feedstock for refining in a fluid catalytic cracking (FCC) unit.[0002]Hydroconversion processes for the conversion of heavy hydrocarbon oils to light and intermediate naphthas of good quality and for reforming feedstocks, fuel oil and gas oil are well known. These heavy hydrocarbon oils can be such materials as petroleum crude oil, atmospheric tower bottoms products, vacuum tower bottoms products, heavy cycle oils, shale oils, coal derived liquids, crude oil residuum, topped crude oils and the heavy bituminous oils extracted from oil sands. Of particular interest are the oils extracted from oil sands and which contain wide boiling range materials from naphthas through kerosene, gas oil, pitch, etc., and which con...
