Embodiment 1
[0052] Put 2g of FCAS-R09 fresh adsorbent in a small fixed-bed reactor, and firstly treat the fresh adsorbent under the conditions of pressure 2.5 MPa, hydrogen (hydrogen reduction gas, the same below) 16L / h and a temperature of 400°C. Hydrogen reduction treatment was performed for 2 hours to obtain the hydrogen reduction adsorbent.
[0053] Using CS with a mass fraction of sulfur of 1% 2 Cyclohexane solution is used as the sulfur-containing material, and when the reaction pressure is 2.5 MPa, the hydrogen gas (hydrogen sulfide gas, the same below) is 16L / h, and the weight hourly space velocity of the sulfur-containing material is 5h -1 1. Under the reaction condition of 300° C., the hydrogen-reducing adsorbent was hydrosulfurized for 4 hours to obtain the hydrogen-sulfide adsorbent.
[0054] After the hydrosulfide treatment, the hydrosulfide adsorbent obtained was subjected to hydrogen conversion treatment at 350° C. for 2 h in a 16 L / h hydrogen gas (hydrogen conversion gas,...
Embodiment 2
[0058] Put 2g of industrial equilibrium adsorbent S1 in a small fixed-bed reactor, first roast and regenerate industrial equilibrium adsorbent S1, the regeneration conditions are: regeneration stage 1, regeneration temperature is 430°C, pressure is normal pressure, regeneration gas is air Mixed gas with nitrogen (8L / h air + 8L / h nitrogen), regeneration for 2h; regeneration stage 2, regeneration temperature is 480°C, pressure is 0.1 MPa, regeneration gas is a mixture of air and nitrogen (12L / h air +4L / h nitrogen), regeneration for 2h; regeneration stage 3, regeneration temperature is 530°C, pressure is 0.1MPa, regeneration gas is 16L / h air, regeneration is 2h.
[0059] The regenerated industrial equilibrium adsorbent S1 was subjected to hydrogen reduction treatment for 0.5h under the conditions of pressure 2.5 MPa, hydrogen gas 16L / h, and temperature 300°C to obtain hydrogen reduction adsorbent S1.
[0060] Then use CS with 1% sulfur mass fraction 2 The cyclohexane solution of...
Embodiment 3
[0065] Put 2g of industrial equilibrium adsorbent S2 in a small fixed-bed reactor, and first roast and regenerate industrial equilibrium adsorbent S2. The regeneration conditions are: regeneration stage 1, regeneration temperature is 430 ° C, pressure is 0.5 MPa, and regeneration gas is Mixed gas of air and nitrogen (8L / h air + 8L / h nitrogen), regeneration 2h; regeneration stage 2, regeneration temperature is 480 ° C, pressure is 0.5 MPa, regeneration gas is a mixed gas of air and nitrogen (12L / h Air + 4L / h nitrogen), regeneration for 2h; regeneration stage 3, regeneration temperature is 530°C, pressure is 0.5MPa, regeneration gas is 16L / h air, regeneration is 2h.
[0066] The regenerated industrial equilibrium adsorbent S2 was subjected to hydrogen reduction treatment for 2 hours under the conditions of pressure 1.5 MPa, hydrogen gas 32L / h, and temperature 400°C to obtain hydrogen reduction adsorbent S2.
[0067] Then use the reformed gasoline solution of dimethyl disulfide w...
