Hydrogenation refinement of reformate

A hydrogenation refining process for reformed oil whose arene with number of carbon atoms greater than 9 has been removed features that the content of arene is 20-85 wt.%, bromine is 0.5-8.0 g/100g of raw materials, and its reaction condition is at 15-200 deg.C, 0.5-3.0 MPa of hydrogen pressure in reactor, 3-15/hr of liquid space speed, and 100-500 of volume ratio of hydrogen to oil. The hydrogenating catalyst is thin Pd/gamma-A2O3 strips with Pd content of 0.15-0.6 wt.%. Its advantages include very low bromine content (0.2g/100g) of refined oil, no loss of arene, and long service life of catalyst (more than 3 years) without regeneration.

The composition range (weight percentage) of the invented catalyst is as follows: CuO 30-52, Cr2O3 28-56, CaO 5-15, 8 oxide 2-14. In the above mentioned catalyst, proper amount of Zn may also be added. Said catalyst can continuously operate over 1300 hr. under the condition of 90-170 deg.C of reaction temp, lower than 0.5 MPa of pressure, input load of furol being 0.1-0.65 g furol catalyst .g.h and 1:7-62 of the molar ratio of hydrogen and furol, the coversion rate of furol still maintains over 95%, the processing quantity of furol for each g of catalyst is as high as 450 g.
