The invention discloses a preparation method and application of a composite modified straw active granule carbon adsorption material. The preparation method of the composite modified straw active granule carbon adsorption material comprises the following steps: 1) mixing straw powder, distilled water, an adhesive and composite minerals, granulating the mixture, and then, putting the granules intoa tube furnace to be pyrolyzed to prepare straw granule carbon; 2) introducing inert gas into a modified reagent, adjusting the pH value of a solution to be 8-11, adding a ferric nitrate solution, andperforming reaction to obtain a composite modified solution; and 3) soaking the straw granule carbon in the composite modified solution for 30min, performing ultrasonic treatment for 1-12h at 1-8MPa,performing centrifugation and drying, putting the dried straw granule carbon into a muffle furnace to be fired for 2-8h at 200 DEG C, and performing cleaning and then drying to obtain the composite modified straw active granule carbon adsorption material. The composite modified straw active granule carbon has a good absorption effect on phosphate radicals in low-pollution water. The adsorption material is convenient to recover, is favorable for recycling of phosphorus resources, and has wide market application prospects.

The invention discloses a high-temperature-resistant anti-rut asphalt mixture which comprises the following raw materials in parts by weight: 15-18 parts of pretreated asphalt, 30-35 parts of zinc chloride, 5-10 parts of heat conduction material, 8-12 parts of glass fiber, 5-10 parts of admixture and 90-100 parts of aggregate. The pretreated asphalt is prepared from the following raw materials in parts by weight: 8-14 parts of modified asphalt, 6-8 parts of dihydroxyl-terminated polydimethylsiloxane, 14-16 parts of polycaprolactone glycol, 2-4 parts of 1, 6-hexamethylene diisocyanate, 0.5-1 part of dibutyltin dilaurate and 4-6 parts 4, 4'-dimethyl-2, 2'-dipyridyl, and 0.5-0.8 part of 1, 4-butanediol. The preparation method is reasonable in process design and proper in component proportion, the prepared asphalt mixture has excellent anti-rutting capacity, the high-temperature stability and the water stability of the asphalt mixture are improved, and the asphalt mixture can be applied to roads with large traffic volume and more heavy-load and overload vehicles and has higher practicability.

The invention discloses a method for synthesizing a porous microsphere material containing NaY zeolite by a waste FCC (fluid catalytic cracking) catalyst, which is a catalytic cracking process. The method is characterized by comprising the following steps: A. adding water and hydrochloric acid to the waste FCC catalyst for mixing slurry and acidizing to obtain catalyst microspheres; B. mixing thecatalyst microspheres with one or a combination of natural kaolin and roasted kaolin, adding water to obtain slurry containing 30-50% of solid, adding a functional agent to the slurry and then forming dried microspheres through spray drying, and roasting the dried microspheres at the temperature of 700-1100 DEG C for 0.5-10 hours to obtain roasted microspheres; and C. adding sodium silicate, a zeolite directing agent and alkali liquor to the catalyst microspheres and / or the roasted microspheres, adding the obtained mixed solution to a crystallization reaction kettle, performing hydrothermal crystallization at the temperature of 85-120 DEG C for 10-30 hours, filtering out a mother liquid, washing the obtained filter cake with deionized water, and then drying to finally obtain the finished product. The method is mainly used for synthesizing the porous microsphere material containing the NaY zeolite.
