Abstract
A kind of hydrofinishing reforming raffinate oil that is used for is by γ-Al to produce the catalyst of NY-70 solvent naphtha
2O
3And the precious metals pt or the Pd that support thereon constitute, and bullion content is 0.02～0.20% weight, and carrier surface area is 150～240 meters
2/ gram, pore volume are 0.45～0.95 milliliter/gram, can several pore radius be 40～200 dusts.This catalyst has not only overcome the disadvantage of industrial existing non-noble metal loading type catalyst purification condition harshness, has saved fuel and energy consumption, and can obtain the fine and quality oil of high yield.This catalyst not only can be used for the hydrofinishing of raffinating oil, and also can be used for the hydrofinishing and the gas cleaning of reformed oil.
Description
The invention belongs to the hydrocarbon oil hydrogenation catalyst for refining.
Regulation according to standard GB 1922-80, the iodine number of NY-70 solvent naphtha must not be greater than 0.5 gram iodine/100 grams, be that the bromine valency must not be higher than 0.3 gram bromine/100 grams, must be when therefore producing this kind solvent naphtha through hydrofinishing with saturated alkene wherein with reforming raffinate oil.Being used for the hydrorefined catalyst of reforming raffinate oil at present is to be the non-precious metal catalysts such as Mo-Co, Mo-Ni of carrier with the activated alumina, though they can reach hydrorefined purpose, need under harsh purification condition, could guarantee that product quality is qualified.
The invention provides the solid supported noble metal catalyst that a kind of purification condition relaxes, is used for the hydrofinishing reforming raffinate oil.
Catalyst of the present invention is by γ-Al
2O
3Support that precious metals pt or Pd constitute.To the central distribution inequality, its content is that 0.02～0.20 heavy %(is benchmark with the carrier from carrier surface for precious metals pt or Pd), be preferably 0.02～0.06 heavy %.γ-Al
2O
3Carrier can be different shape, as sheet, strip, spherical or other shape; Its surface area is 150～240 meters
2/ gram is preferably 160～200 meters
2/ gram; Pore volume is 0.45～0.95 a milliliter/gram, is preferably 0.75～0.95 milliliter/gram; Can several pore radius be 40～200 dusts, be preferably 120～160 dusts.
This Preparation of catalysts method is identical with common solid supported noble metal catalyst: use the salt solution impregnation γ-Al that contains Pt or Pd noble metal in the presence of competitive adsorbate
2O
3Carrier, reduction gets product in roasting in soaked carrier drying, the air, the hydrogen.
Catalyst of the present invention is compared with the loaded non-precious metal catalyst of present use has following advantage:
1. hydrofinishing condition relaxes, purification efficiency height (data see Table 1), thus saved fuel and energy consumption.
Table 1
2. the catalyst activity height can make the whole hydrogenation of alkene in raffinating oil saturated under the condition that relaxes; Normal pressure and about 200 ℃ benzene and toluene there is hydrogenation activity; Under normal temperature and normal pressure, can remove the oxygen in the dehydrogenation, so this catalyst not only can be used for the hydrofinishing of raffinating oil, also can be used for the hydrofinishing and the gas cleaning of reformed oil.
3. the refined oil yield can be near 100 heavy %, and the bromine valency can reach 0.2 * 10
-3～5.0 * 10
-3Gram bromine/100 grams.
Example 1
Under the condition that different competitive adsorbates exist, with the γ-Al of the salt solution impregnation different size that contains Pt or Pd noble metal
2O
3Carrier all can make catalyst of the present invention through super-dry, roasting, reduction then, and is as shown in table 2.
Example 2
Mo-Co/ γ-Al with A, B described in the example 1, C, D, E catalyst and industrial existing use
2O
3Catalyst carries out reforming raffinate oil (the bromine valency is 6～10 gram bromines/100 grams) hydrofinishing evaluation test respectively in 200 milliliters of tubular reactors.The result shows that the hydrofinishing performance of catalyst of the present invention significantly is better than the base metal industrial catalyst of existing use, sees Table 3.
Table 3
Example 3
In 200 milliliters of tubular reactors, under the different condition reforming raffinate oil (the bromine valency is 6～10 gram bromines/100 grams) is carried out the hydrofinishing evaluation test with catalyst A described in the example 1, all obtain good result, see Table 4.
Table 4
Example 4
With catalyst A described in the example 1, C and E, in 200 milliliters of tubular reactors, carry out service life evaluation testing (feedstock oil bromine valency 6～10 gram bromines/100 grams), the result shows that catalyst of the present invention is very hopeful industrialized, sees Table 5.
