The invention discloses high-energy and environment-friendly renewable clean fuel and a preparation method thereof, and belongs to the technical field of a new energy source fuel. The high-energy and environment-friendly renewable clean fuel is prepared from the following raw materials by mass percent: 65.43% of methanol, 30.5% of auxiliary material, 3.3% of denaturing agent, 0.57% of dissolving-assisting and pungent-increasing additive, and 0.2% of dispersant. The high-energy and environment-friendly renewable clean fuel produced by the method disclosed by the invention has the significant progresses that 1, the traditional fuel can be fully and comprehensively replaced, and the realistic problem of crisis of global energy can be solved; 2, the high-energy and environment-friendly renewable clean fuel is wide in raw material range, and free of emission of three wastes in the production process; 2, the high-energy and environment-friendly renewable clean fuel is broad in applicable range, and the operating requirements of kinds of fields such as industries and the like can be met; 4, the consumption is lower than that of the traditional fuel under the same condition, the environmental index is that over 80% of emission is reduced in comparison with the traditional fuel, and energy conservation and emission reduction are really achieved; 5, the high-energy and environment-friendly renewable clean fuel is high in cost performance, and the price of the product does not change along with fluctuation of the international crude oil price, and is stable; and 6, the high-energy and environment-friendly renewable clean fuel is high in safety performance.

The invention discloses a method for high-yielding benzene from C6 alkane. The method is to remove normal hexane through an adsorber and remove light and heavy components through a deisohexane tower after heating the C6 alkane raw material; The side line components of the alkane tower and the hydrogen raw material are dehydrated and heated, and then enter the reactor system for reaction; the reaction product is subjected to gas-liquid separation I, and the obtained gas phase is pressurized to undergo gas-liquid separation II, and the gas phase part enters the desorber for desorption The n-hexane enters the reaction system; the liquid phase obtained from gas-liquid separation I enters the depentanizer, and the overhead stream enters the debutanizer together with the liquid phase obtained from gas-liquid separation II, and the bottom pentane component and deisohexane The isohexane and heavy components removed by the tower are taken out as gasoline blending components; the bottom stream of the depentanizer enters the extraction tower to extract benzene, and the bottom stream is sent to the separation system to separate benzene, and the top stream circulates into the reaction system ; The method greatly improves the utilization rate of active components in C6 alkanes, removes most of the water in the raw material, and solves the problem of accumulation of light and heavy components in the reaction system.

The invention relates to the field of bamboo cultivation and bonsai gardening, in particular to a method for manufacturing a bonsai through chosen or cultured bamboo rhizome and stump. The method includes: (1) bamboo species range selection; (2) bamboo rhizome collection and early-stage culturing which comprise two ways: 1, bamboo rhizome collection and culturing: embedding the collected bamboo rhizome or bamboo stump in a garden for culturing, fully pouring root stabilizing water after the embedding, then covering the bamboo rhizome or bamboo stump through a covering object, and taking the seedlings out for use after the growing bamboo shoot sprouts and the bamboo root grows for a while; and 2, coiled stump culturing of the bonsai: in early spring, summer or autumn, planting the bamboo in the bonsai to enable the root of the bamboo rhizome to be coiled in a pot, then taking the bonsai bamboo out from the pot, cutting off the bamboo stalk, embedding the bamboo stump with a soil ball into the garden or the pot, and using the bonsai after the bamboo shoot is sprouted from the bamboo rhizome; (3) bonsai culturing method; (4) appearance design; and (5) managing and protecting culturing. The method for manufacturing bamboo rhizome and stump bonsai provides new products of bamboo rhizome and stump bonsai for garden markets, and the new products have wide meanings in culture, art, economy and society.

An additive for middle-or low-strength concrete is prepared from powdered coal ash (88-98 wt.%), dedusted ash (0.38-6.18%), calcium lignosulfonate (0.15-1.5%), sodium chloride (1-4%), triethanolamine(0.1-0.2%) and rosin soap (0.02-0.1%). Its advantages include widely available raw materials, low cost, and high performance of concrete.

The invention relates to a preparation method of a pre-laid waterproof coiled material for concrete mortar bonding construction. According to the technical scheme, the preparation method comprises the following steps: fully applying an SIS hot-melt pressure-sensitive adhesive to a modified polyethylene plastic waterproof main body layer by virtue of a hot-melt pressure sensitive adhesive coating machine, so as to form an SIS hot-melt pressure-sensitive self-sticking layer, and then coating the hot-melt pressure-sensitive self-sticking layer with a weather resistant mineral grain functional layer with cement reactivity and an anti-sticking isolation membrane positioned on one side of the coiled material. The preparation method has the beneficial effects that (1) a novel wet bonding technique is provided, the coiled material and structural concrete are permanently and organically combined, no water channeling hazards exist between the coiled material and the structural concrete, and the reliability of a waterproof layer is improved; (2) the impact resistant performance and the puncture resistant performance are excellent, and the construction load which directly acts on the pre-laid waterproof coiled material and the impact of a steel skeleton can be born; (3) strong chemical resistance is provided; (4) the construction is convenient, and a leveling blanket is not needed; (5) the waterproof coiled material and a basic layer are in border adhibiting without influence of sedimentation deformation of the basic layer.
