Problems solved by technology
At present, activated carbon is generally used to adsorb gasoline vapor in automobiles. Because activated carbon adsorption is easy to be saturated, the replacement speed is fast, secondary treatment is not easy, and the recycling effect is poor, so there is an urgent need for an adsorption with good separation effect, large adsorption capacity, and good recycling effect. agent

Embodiment Construction
[0013] The present invention will be described in detail below through specific examples.
[0014] An adsorbent capable of absorbing gasoline vapor, made of the following raw materials in parts by weight (kg): calcium carbonate fiber 12, tetrabutyl titanate 34, silica sol 4, calcium aluminate 7, volcanic rock 76, PA6 nylon powder 8 , gelatin 3, ammonium bicarbonate 2, polystyrene microspheres 6, gypsum powder 5, appropriate amount of deionized water;
[0015] A kind of adsorbent that can absorb gasoline vapor described in the present invention is made by following specific steps:
[0016] (1) Mix tetrabutyl titanate with 4 times the amount of absolute ethanol, stir magnetically for 1 hour, chop calcium carbonate fibers and add them to the above solution, continue magnetic stirring for 2 hours, slowly add deionized water dropwise, and wait for the formation of Continue to stir for 0.6 hours after the gel, then add it to an oven for drying and grinding at 80°C for subsequent us...

Abstract
The invention discloses an adsorbent capable of adsorbing gasoline steam. The adsorbent is characterized by being prepared by the following raw materials, by weight part: 8-15 of calcium carbonate fiber, 20-40 of tetrabutyl titanate, 3-5 of silica sol, 6-8 of calcium aluminate, 60-80 of volcanic rock, 6-9 of PA6 nylon powder, 3-4 of gelatin, 1-3 of ammonium bicarbonate, 5-7 of polystyrene microsphere, 4-5 of gypsum powder, and a proper amount of deionized water. Polystyrene microsphere and gypsum powder added in the adsorbent have a synergistic effect, and are good in adsorption effect on gasoline steam and large in adsorption capacity, so that pollution of overflowed steam to the environment is greatly reduced. The prepared adsorbent has excellent adsorption effect, is good in adsorption efficiency, easy to remove, good in reuse effect, and low in cost, is free of pollution, and is suitable for industrial production.
Description
technical field [0001] The invention relates to the field of adsorbents, in particular to an adsorbent capable of adsorbing gasoline vapor and a preparation method thereof. Background technique [0002] The pollution of the environment by automobiles has become the first source of urban air pollution. The pollution of the atmosphere by automobiles mainly comes from the evaporation of automobile exhaust and fuel gas, of which exhaust pollution accounts for 70% and fuel vapor pollution accounts for 30%. At present, activated carbon is generally used to adsorb gasoline vapor in automobiles. Because activated carbon adsorption is easy to be saturated, the replacement speed is fast, secondary treatment is not easy, and the recycling effect is poor, so there is an urgent need for an adsorption with good separation effect, large adsorption capacity, and good recycling effect. agent. [0003] The texture of volcanic rock is as hard as natural stone. The surface of the coating is h...
