Description
Technical field
The utility model is related to a kind of mixed reactor, the full back-mixed reactors of more particularly to a kind of coal tar hydrogenating.
Background technology
Since in recent years, a large amount of exploitations of petroleum resources, international energy supply conditions are extremely in short supply, by the height of international crude petroleum
The influence of price, cost sharply increase.This project coal tar obtains hot low point of oil and cold low point of oil after adding hydrogen, directly send
The carbolineum Hydrogenation raw oil surge tank in downstream, the part as carbolineum hydrogenating materials.By People's Republic of China's industry and letter
Two 〇 〇 of breathization portion on December 19th, 8 " industry [2008] the 15th " text spirit meets the industry of country and technology drum
Project demand is encouraged, using coal tar as raw material, is combined with green technology, the production oil product that price rises steadily currently on the market, root
Current coal tar processing existing defective workmanship in the process is controlled（Product quality is unqualified, pollution transportation）, realize coal tar
The increment of resource utilizes.
Coal tar hydrogenating technology be exactly using fixed bed hydrogenation treatment technology by contained by coal tar metal impurities, ash content and
S, the hetero atoms such as N, O remove, and alkene therein and arene compounds are carried out saturation and carry out the excellent naphtha of the quality of production
Fraction and diesel oil distillate.Mainly the factor of influence coal tar hydrogenating unit operation cycle, product yield and quality is：Reaction pressure
Power, reaction temperature, volume space velocity, hydrogen to oil volume ratio and raw material oil nature etc..Reactor pressure and/or cycle hydrogen purity are improved,
It is also to improve reaction hydrogen partial pressure.Reaction hydrogen partial pressure is improved, hetero atoms and the aromatization such as S, N being not only advantageous in removing coal tar
It closes object and adds hydrogen saturation, improve the quality of Related product, and the coking rate of catalyst can also be slowed down, extend making for catalyst
With the period, the expense of catalyst is reduced.The raising of hydrogen partial pressure is but reacted, can also increase plant construction investment and operating cost,
Reaction temperature is improved, hydrogenation reaction rate can be accelerated and is hydrocracked rate.Excessively high reaction temperature can reduce aromatic hydrogenation saturation
Depth makes fused ring compound condensation green coke shorten the service life of catalyst, improves reaction volume air speed, can make coal tar hydrogenating
The processing capacity of device increases.For newly-designed device, high volume space velocity can reduce the investment of device and buy catalyst
Expense.Relatively low reaction volume air speed can obtain desired product yield under relatively low reaction temperature, while extend catalysis
The service life of agent, but the economy that too low volume space velocity will directly affect device, the size of hydrogen to oil volume ratio are mainly
To add the chemical hydrogen consumption that hydrogen is fed as foundation, describe plus what hydrogen was fed needs hydrogen amount relative size.Coal tar hydrogenating is than one
As petroleum-type raw material, it is desirable that have higher hydrogen-oil ratio, the reason is that coal tar composition be based on aromatic hydrocarbons, need during the reaction
More hydrogen are consumed, in addition aromatic hydrogenation saturated reaction is a kind of strong exothermal reaction process, and the hydrogen for needing sufficient amount will
Reaction heat is taken away from reactor, avoids hydrogenation plant " temperature runaway ".
But it is loaded and unloaded in coal tar hydrogenating and is not easy to be controlled, therefore people wish in the new hydrogen of agent and flushing oil press process
Prestige has a kind of equipment to control this, so as to the production of safe and reliable progress coal tar conversion fuel oil.
