Description
Technical field
This utility model relates to a kind of portable minisize High Temperature High Pressure thermal cracking of heavy oil Fast Evaluation reaction unit.
Background technology
World oil supply forward the trend development of heaviness, in poor quality.The Efficient Conversion of inferior heavy oil and cleaning profit
With becoming the focus received much concern the most both at home and abroad, " molecule oil refining " concept is arisen at the historic moment.Molecule oil refining is exactly from dividing
Sub-level recognizes petroleum refining process, Accurate Prediction product property, optimizes technique and work flow, promotes the valency of each molecule
Value.
Mink cell focus has high boiling point, high viscosity, high heat-labile feature, and sulfur, nitrogen, oxygen and metal heteroatom content are high,
Gum asphaltic content is high, is the extremely complex mixture of composition, structure, character.Character composition according to heavy oil practical measurement
Inferred from input data, containing heteroatomic compounds such as sulfur, nitrogen, oxygen in major part molecule in mink cell focus.It is shadow that heteroatomic compound converts
Ring technical process and the deciding factor of product quality.In different crude oils containing hetero atom (S, N, O) compound molecule type and
Distribution in each fraction there are differences, and enters after secondary operations device, the heteroatomic compound distribution of raw material, conversion level and
The performance synthesis of catalyst and carrier thereof affects hetero atom molecule in the whole course of processing and converts, thus to course of processing product matter
Amount, equipment corrosion, environmental conservation cause Different Effects.China's import processing oil variety is changeable, the composition of heteroatomic compound
Hetero atom distribution and the difficulty of removing in impact processing product, along with the requirement of clear gusoline is increasingly stricter, the change of raw material
Qualified the dispatching from the factory of product is carried
Go out bigger challenge, from molecular composition level, heteroatomic compound oil and processing product thereof is furtherd investigate
Seem increasingly important.
Modification and the process technology present situation of current mink cell focus are as it can be seen, the mink cell focus of substantially 70% uses hot-working
Technology, the mink cell focus of 30% uses catalyzed conversion processing scheme.
Heavy oil molecules transformation rule in research hot procedure, is prerequisite in " molecule oil refining " technology evolution
Basic data.Heavy oil reaction rule in hot procedure has had many scholars in research, but is essentially all weight
Oil carries out thermal response as an entirety, is changed by the composition and property of contrast raw material and product, infers reaction mechanism.Due to
Heavy oil composition complexity, interacts between component during reaction, so cannot obtain definite reaction rule.More careful in order to obtain
Result, have scholar heavy oil is divided into saturated point, fragrance point, resin and asphalt four component, it is intended to study the reaction of four components
Rule.But owing to four Component seperation processes are loaded down with trivial details, complicated, heavy oil is divided into four components and carries out the thermal conversion reaction of reality, work
Measure the biggest.Therefore, scholar is generally also heavy oil as an entirety, is reacted the change of before and after four component by contrast, comes
Infer its reaction rule, be also one indirectly mode.And in order to study the reaction rule of heteroatomic compound, do the most accurately
Method is according to extraction chromatography, heavy oil to be separated into the main heteroatomic compound containing S, N, O then carry out thermal conversion reaction.But
Being that the sample size that this separate mode once obtains is less, the workload carrying out thermal conversion reaction needs is bigger.
Therefore, in order to obtain either four components or the reaction rule of heteroatomic compound, it is necessary to by heavy oil according to respectively
The mode of kind is separated into narrow component and carries out thermal conversion reaction again.The high-temperature high-pressure reaction kettle volume of use for laboratory is relatively big at present, once
Testing raw materials used more, usually single channel reactive mode, single test can only fix a reaction condition.Reactive mode one
As be material add reactor seal after begin to warm up again, react rise to target temperature go to toward have begun to reaction, it is impossible to
Actual response state under reflection predicted temperature.Mode of heating uses constant heating rate, and " temperature runaway " phenomenon often occurs,
Control accuracy is poor, causes test data the most accurate.And position is fixed after installing, it is impossible to mobile.
Utility model content
Problem to be solved in the utility model is big for existing use for laboratory high-temperature high-voltage reaction device volume, single
Reaction doses is many, and material cannot synchronize to react under target temperature, and single test can only fix a reaction condition, examination
