Description
Technical field
The invention belongs to Petroleum Processing Technology fields, and in particular to a kind of processing inferior heavy oil production vehicle fuel and road
The method of pitch.The method that the poor product of property is converted to high added value asphaltic products, this method are based on general refinery
Existing production technology can be realized.
Background technology
The heaviness trend of world's crude oil is constantly aggravated, and refinery's processing poor quality, the ratio of heavy crude constantly increase.How
It is refinery's problem in the urgent need to address that inferior raw material, which is processed into high added value oil product,.The characteristics of inferior heavy oil be colloid,
Asphalitine, metal, sulphur, nitrogen content are high, and viscosity is also very big.These features of inferior heavy oil lead to that its process difficulty is big, production
Product yield is low, of poor quality.Thus, it is that domestic and international oil Refining Technologies are sent out by the oil product that inferior heavy oil efficient transition is high added value
The core of exhibition.
Currently, the technique of heavy oil Efficient Conversion has hydrotreating, delayed coking, catalytic cracking and is hydrocracked, these works
Skill respectively has advantage and disadvantage in adaptability to raw material, liquid product yield and liquid product mass etc., especially processes inferior heavy oil
Shi Jun is presented with very distinct issues.These techniques are lacked for the purpose of inferior heavy oil is largely processed into vehicle fuel
Core technology, product increment is relatively low after processing.
Catalytic cracking is most widely used heavy oil lighting technique in refinery, and the slurry oil inferior of gained lacks rational add
Work method causes the serious waste of resource.Therefore, it is to improve processing of heavy oil economic benefit reasonably to utilize catalytic cracked oil pulp
Key factor.
Invention content
It is a primary object of the present invention to the deficiencies for existing heavy oil conversion technology, provide a kind of new processing inferior heavy
The method of oil, the bad heavy distillate high to sulphur nitrogen content, tenor is high, asphalt content or carbon residue are high or residual oil carry out
Selective solvent depitching obtains a series of quality raw materials for catalytic cracking/be hydrocracked, and obtains good road asphalt tune
And component, liquid component yield is improved, value of the product, the object that reduces environmental pollution discharge are improved.Specific technical solution is as follows：
A method of processing inferior heavy oil production vehicle fuel and road asphalt include the following steps：
1) inferior heavy oil is added in extraction equipment, selective solvent depitching, the selective solvent is carried out to it
For one or more of propane, butane, pentane mixed solvent, extracting pressure 4.0-9.0MPa, temperature are 140-180 DEG C；
2) the frivolous coal tar LDAO that will be obtained at the top of extraction equipment, into catalytic cracking/hydrocracking unit production combustion
Expect the base oils such as oil, lubricating oil；
3) heavy constituent for obtaining extraction equipment bottom, i.e. heavy deasphalted oil HDAO and de-oiled asphalt DOA；With from step
2) the heavy oil slurry oil mixture manufacturing road asphalt of catalytic cracking；
The heavy oil include reduced crude, decompression residuum, coal tar, oil sands bitumen and other devices heavy constituent or this
One or more of mixtures of a little raw materials
When the heavy oil of processing is decompression residuum inferior, asphaltene in vacuum residues is removed by solvent deasphalting, is obtained
Sulphur, nitrogen, tenor and carbon residue are substantially less than the frivolous coal tar and heavy deasphalted oil of vacuum residuum feed.General industry is molten
Agent depitching uses propane for solvent, and the macromolecule hydrocarbons such as preferred pentane of selective solvent proposed by the present invention are solvent.In order to
The higher value application of heavy oil is improved, the present invention proposes that the cycle slurry oil that will be obtained in catalytic cracking process is partly or entirely used as road
Road pitch blend component.
Beneficial effects of the present invention：
1, inferior heavy oil can use conventional oil refining process to carry out catalyzed cracking processing, without using the other of high energy consumption
Technique, to the significant investment for reducing processing inferior heavy oil and operating cost；
2, super inferior heavy oil passes through selective solvent depitching, removes most of metal and is easy to deposit the pitch of green coke
Matter obtains frivolous coal tar and heavy deasphalted oil；
3, catalytic cracked oil pulp as and blend component of the de-oiled asphalt as road asphalt, improve two kinds of low value products
Added value；
4, deasphalted oil makes the byproducts such as catalytic cracked dry gas, coke and total hydrocarbon damage as good catalytically cracked material
Lose significant reduction.
