Description
Technical field
The utility model is the FCC tests device that use in a kind of laboratory, is applied to petrochemical industry.
Background technology
Catalytic cracking is a kind of important secondary operations technology in the petroleum refining process.The riser catalytic cracking experimental rig that is used for analoging industrial device in the laboratory is crucial, the necessary tool of research catalytic cracking.
Abroad, the report of relevant riser catalytic cracking experimental rig, the ARCO device [1] [2] that has U.S. Atlanti Richfild company to develop the earliest, it can react-regenerate running continuously.Riser reactor is to be connected in series by several close phase back-mixing fluid beds, non-plug-flow reaction state, so reaction effect and commercial plant differ greatly.Aspect catalyst control, do not adopt guiding valve and use probe, the control effect is obviously bad, and the catalyst circulation amount is very unstable.In addition, because of it does not install the atomizing raw materials nozzle, charging can only be light oil or distillate, can not advance heavy oil.

[2] catalytic cracking process and engineering
At home, produce the more riser catalytic cracking experimental rig of use two kinds of forms are arranged.A kind of imitated basically ARCO device is still controlled catalyst circulation with probe, only does some changes in some aspects; Another kind has been done bigger improvement on the ARCO device basic.Its flow process is seen Fig. 1
The inlet amount of this device is 1-1.2 kilograms/hours.The settler of reaction-regeneration system and regenerator two device height differ seldom, and riser is very short.In riser bottom atomizing feed nozzle is housed, be used for the raw material dispersion that atomizes, so charging not only can be that distillate also can be a heavy oil; In the regenerator sloped tube bottom restriction orifice is housed, with the circulation of two device pressure reduction control regenerated catalyst.This device performance of evidence is better, considerably beyond the ARCO device.
As the analogue means of commercial plant and as scientific research institution's experimental rig, said apparatus also exists perfect inadequately and convenience.One, owing to be subjected to the restriction of riser caliber and nozzle arrangements, said apparatus can only be installed nozzle vertically upward in riser bottom, and raw material enters riser and contacts with regenerated catalyst at first and react at a turbulent region like this, and this and commercial plant operating mode are completely different.Regenerated catalyst enters behind the riser from the bottom by pre-lifting steam and upwards promotes after the rectification and enter the raw material haptoreaction from the side in the commercial plant.Above-mentioned experimental rig reaction effect can not show a candle to commercial plant.Its two, above-mentioned experimental rig has only the charging aperture in bottom, and is definite when manufacturing and designing usually because of riser length, thus will change the reaction time can only change the oil gas linear speed and realize by the quantity of steam that changes inlet amount or injection.Reach the change reaction time if require not change the oil gas linear speed, above-mentioned experimental rig is not accomplished.In addition, single charging aperture can't be realized the compound charging of the diverse location of plurality of raw materials.Its three, adopt probe, guiding valve and additive method far to be unable to catch up with using plug valve effective to the control aspect of catalyst partial circulating amount.Its four, in same riser, realize the reaction of the different oil ratios of two sections, said apparatus is not more accomplished.In a word, these install not only that test effect and commercial plant exist than big-difference, also do not satisfy the test demand of multiple reaction condition catalytic cracking process and evaluating catalyst.
Summary of the invention
For overcoming the problem of existing apparatus in deficiency aspect the analoging industrial device and function singleness bad adaptability, the utility model provides a kind of multi-functional riser catalytic cracking experimental rig, the conventional inlet amount of this device is 1.5-3 kilograms/hours, the maximum feed amount is 1.5-8 kilograms/hours, is made up of feeding assembly, reaction-regeneration system, product recovery and gauge assembly and computer control system.Reaction-regeneration system of the present utility model and commercial plant are quite similar, can adapt to the FCC tests of kinds of processes condition flexibly, easily.Its flow process of the utility model is seen Fig. 2.
The technical scheme that its technical problem that solves the utility model adopts is:
1. with reference to the commercial plant common type, the settler of reaction-regeneration system of the present utility model and regenerator adopt two devices height block form structure, inverted "L" shaped riser.
2. the utility model also is provided with the charging aperture of a plurality of chargings from the side except that being provided with the charging aperture of band atomizer in the riser bottom with the upper part in the bottom.The bottom feed mouth does not advance raw material usually, only advances the pre-lifting (yet can advance raw material in case of necessity) that steam is used for regenerated catalyst.The above charging aperture in bottom is selected one of them charging according to the needs in reaction time, also can adopt the charging aperture charging simultaneously of diverse location to different material.For satisfy heavy oil into requirement, the atomizing raw materials nozzle is housed in the charging aperture of charging from the side equally, this nozzle is a kind of special construction, raw material enters the back from the nozzle level changes 90 ° along the upwards atomizing ejection of riser axis normal.
3. the utility model adopts vertically arranged small-sized plug valve control catalyst circulation.Similar to commercial plant, plug valve control stripping tube inner catalyst material level to be generated, the regeneration plug valve is then controlled the regenerated catalyst internal circulating load, comes the oil ratio and the temperature of stably catalyzed cracking reaction with this.
4. riser of the present utility model has adopted segmentation heating and temperature control, with Temperature Distribution up and down in this analoging industrial device riser.The section with the section between the employing quickly assembled and disassembled being connected, realize changing flexibly and easily the riser of different tube diameters as required with this.
5. the utility model also is provided with an inlet port again except that being provided with the regenerated catalyst inlet port in the riser bottom on top.Hypomere is a popular response.Epimere remedies because the catalyst activity reduction that the hypomere reaction is caused increases epimere reactant oil ratio simultaneously with this by additional high activated catalyst, realizes promoting the purpose of reaction effect, increase conversion ratio with these technical measures.All experimental rigs so that commercial plant still do not possess this technology at present.
The effect that the utility model is useful is that test data and industrial production real data have better comparativity.The test demand of multiple reaction condition catalytic cracking process and evaluating catalyst has been satisfied in its flexibility well.
