Embodiment 1
[0031] Embodiment 1, preparation light oil desulfurizer:
[0032] 1) After mixing 20g of basic zinc carbonate and 30g of ammonium bicarbonate, add it to 60g of ammonia water, dissolve it, and obtain zinc ammonium solution, wherein the mass fraction of ammonia water is 10%;
[0033] 2) Set the specific surface area to 300m 2 / g, the coal-based activated carbon that the mechanical pressure resistance strength is 40N / cm is impregnated in 100g described zinc ammonium solution, obtains the coal-based activated carbon after impregnating, wherein the temperature of impregnating is 20 ℃, and the time is 3h;
[0034] 3) Dry and roast the impregnated coal-based activated carbon in sequence to obtain a light oil desulfurizer, denoted as A1, wherein the drying temperature is 100°C and the time is 5h; the roasting temperature is 300°C and the time is 4h, By using BET (specific surface area analyzer) to test A1, it is found that its specific surface area will increase, due to the ammoniati...
Embodiment 2
[0035] Embodiment 2, preparation of light oil desulfurizer:
[0036] 1) After mixing 40g of basic zinc carbonate and 20g of ammonium bicarbonate, add it to 80g of ammonia water and dissolve it to obtain zinc ammonium solution, wherein the mass fraction of ammonia water is 20%;
[0037] 2) Set the specific surface area to 400m 2 / g, the bamboo charcoal that resistance to mechanical pressure strength is 60N / cm is impregnated in the described zinc ammonium solution of 130g, obtains the impregnated bamboo charcoal, wherein the temperature of impregnation is 25 ℃, and the time is 1h;
[0038] 3) Dry and roast the impregnated bamboo charcoal in sequence to obtain light oil desulfurizer, denoted as A2, wherein the drying temperature is 120°C and the time is 3h; the roasting temperature is 200°C and the time is 5h. BET (specific surface area analyzer) test A2, found that its specific surface area will increase, due to ammonium bicarbonate and ammonia water ammoniated activated carbon...
Embodiment 3
[0039] Embodiment 3, preparation light oil desulfurizer:
[0040] 1) After mixing 30g of basic zinc carbonate and 10g of ammonium bicarbonate, add it into 50g of ammonia water, dissolve it, and obtain zinc ammonium solution, wherein the mass fraction of ammonia water is 15%;
[0041] 2) Set the specific surface area to 550m 2 / g, the wooden activated carbon that the mechanical pressure resistance strength is 50N / cm is impregnated in the described zinc ammonium solution of 150g, obtains the wooden activated carbon after impregnation, wherein the temperature of immersion is 30 ℃, and the time is 2h;
[0042] 3) The impregnated woody activated carbon is dried and roasted sequentially to obtain a light oil desulfurizer, denoted as A3, wherein the drying temperature is 110°C and the time is 2h; the roasting temperature is 250°C and the time is 2h. Using BET (specific surface area analyzer) to test A3, it is found that its specific surface area will increase, which is due to the am...
