Concrete operations parameter is as follows, temperature of reaction: 500 ℃, and regeneration temperature: 680 ℃, raw material preheating temperature; 260 ℃, agent-oil ratio: 6; Its empty is consistent with the operational condition of adding auxiliary agent.During use, catalytic cracking is joined in riser tube entrance stock oil pipeline with volume pump continuously with the auxiliary agent that increases yield of light oil.The dosage of auxiliary agent is 100ppm, and add-on is in stock oil.
The essential property of test raw material oil is as shown in table 1.
Table 1 test raw material oil essential property
3, catalyzer
The catalyzer that test is selected is LDO-70.
4, experimental result data
Table 2 adds the result contrast of auxiliary agent and blank test
Note: (1) lightweight oil %=(gasoline+diesel oil) %
(2) total liquid is received %=(liquefied gas+gasoline+diesel oil) %
As can be seen from Table 2, add auxiliary agent of the present invention and improved yield of light oil, reduced the yield of coke and heavy oil.
5, add the contrast of agent front and back to product property
Quality of gasoline contrast before and after table 3 adding assistant
(described auxiliary agent is the B product that embodiment 2 makes)
Diesel quality contrast before and after table 4 adding assistant
(described auxiliary agent is the B product that embodiment 2 makes)
By table 3, table 4, can find out that the zero pour of diesel oil declines to some extent, low-temperature fluidity is better; The element such as S, N does not have to introduce substantially; Corresponding boiling range is substantially without changing, i.e. oil product corresponding startability, acceleration characteristics and evaporate that degree is unchanged completely in engine improved the low temperature flowability of oil product without impact time on quality product after hence one can see that adding assistant.
The above, be only preferred embodiment of the present invention, not technical scheme of the present invention done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical scheme of the present invention.
