Description
Technical field
The present invention relates to a kind of catalytic hydrocarbon reorganization treatment process, the treatment process of particularly a kind of catalyzing hydrocarbon for recombinant production of high-quality gasoline, diesel oil and chemical industry light oil.
Background technology
Catalytic cracking, catalytic pyrolysis and heavy oil catalytic pyrolysis technology are the core technologies of oil refining, and catalytic cracking is divided into wax catalysis cracking, heavy oil fluid catalytic cracking; The oil gas that generates from the reaction-regeneration system of these technologies is referred to as catalytic hydrocarbon, and the gained catalytic hydrocarbon generally is the main fractionating tower fractionation through processing treatment, can fractionate out products such as dry gas, liquefied gas, gasoline, diesel oil, heavy oil.
More and more strictness along with environmental requirement, the standard of gasoline, diesel oil improves constantly, existing catalytic hydrocarbon is showed following deficiency through the fractionated processing and treating method of separation column: one is that the gasoline produced of this treatment process and the quality of diesel oil have much room for improvement: the olefin(e) centent of gasoline is higher, octane value is on the low side, and diesel-fuel cetane number is on the low side; The 2nd, above-mentioned treatment process can not be produced the gasoline of multiple label simultaneously, and range of product is single; The 3rd, the demand in the diesel oil of being produced, the ratio of gasoline and market does not match, and diesel oil can not satisfy the demands, and gasoline supply exceed demand.
The principal element that influences gasoline product quality is the olefin(e) centent of gasoline and the octane value of gasoline.At present, oil refining enterprise takes to increase the measure of gasoline octane rating: 1. increase high octane value gasoline blending component, generate oil, isomerization generation wet goods as reformed oil, alkylate oil, etherificate; 2. adopt new catalyst; 3. adjust the Hydrocarbon Content by Catalytic Cracking Operation condition; 4. adjust gasoline boiling range scope.
There is following point in above-mentioned measure: the restriction that 1. construction investment is huge, process cost is high, scale is subjected to raw material, the irrational utilization that has resource simultaneously, as reformed oil is the main raw material of producing polyester, a large amount of reformed oils are used for high octane value gasoline blending component, have then aggravated original just polyester raw material degree in short supply very in short supply; 2. adopt new catalyst, can increase the octane value of gasoline, still, can cause olefin content in gasoline to increase considerably, diesel and gasoline ratio reduces; 3. adjust the Hydrocarbon Content by Catalytic Cracking Operation condition, increase the measure of gasoline octane rating, can cause olefin content in gasoline to increase equally, diesel and gasoline ratio reduces; 4. adjust gasoline boiling range scope, increase the measure of gasoline octane rating, it is little to adjust remaining, also can cause olefin content in gasoline to increase.All by the measure that increases alkene and increase gasoline octane rating all with to carry out new gasoline standard inconsistent.
At present, the measure of taking to reduce alkene mainly is: 1. adopt olefine lowering catalyst; 2. the catalytic gasoline segmentation is carried out hydrogenation and non-hydrotreatment; 3. adopt gasoline freshening technology such as double lifting leg.
There is following point in above-mentioned measure: 1. adopt olefine lowering catalyst, can cause gasoline octane rating obviously to reduce; 2. hydrogenation and non-hydrotreatment technology are carried out in the catalytic gasoline segmentation, though can reduce olefin(e) centent, the octane value of gasoline does not increase, and this technological investment is bigger, is subjected to the restriction of hydrogen resource simultaneously; 3. adopt gasoline freshening technology such as double lifting leg, it is limited to reduce the alkene amplitude, and this technical innovation project and technical difficulty are bigger, and the octane value of gasoline does not increase simultaneously.
Diesel-fuel cetane number is the key problem of diesel quality, the major measure that increases the catalytic diesel oil cetane value at present is high-pressure hydrogenation and high-pressure hydrogenation combination technique, catalytic diesel oil cetane value after high-pressure hydrogenation and the processing of high-pressure hydrogenation combination technique has a more substantial increase, but the construction investment of this technology is huge, running cost is very high, be subjected to the hydrogen resource limit.
