Method for synthesizing silicon aluminum orthophosphate molecular sieve using white bole

The invention relates to a method of molecular sieve catalyst synthesis using the kaolin for the synthesis of silicon aluminum phosphate molecular sieve, belonging to the technical field of the preparation of the catalyst materials. The invention is characterized in utilizing the low-cost kaolin as materials. Through (1) roasting the kaolin in the high temperature to gain the crystal aluminum sources and silicon sources; (2) mixing the kaolin with the phosphorus sources and the template agent with the deionized water, processing hydro-thermal crystallization, and roasting and activating the products after washing and drying, the catalyst of the silicon aluminum phosphate molecular sieve can be gained. The structure of the silicon aluminum phosphate molecular sieve is CHA or the intergrowth of CHA and AEI. The invention has the advantages of smaller or lamellar structure molecular sieve gains of the prepared catalyst, which can be used for the process of making olefin from the oxygenic compounds like the limited diffuse alcohol ether to gain the good activity of reaction and the product selectivity, and further the directly application of the catalyst carried by the kaolin micro sphere into fluidized bed reactor.

High-temperature antioxidizing paint for lowering oxidation burning of steel in heating furnace

InactiveCN101462859AReduce high temperature oxidation burning lossReduce oxidation burning loss per unit areaLithium metasilicateHigh pressure water
The invention relates to a high temperature anti-oxidation coating capable of reducing the oxidation burning loss of stainless steel in a heating furnace. The high temperature anti-oxidation coating is characterized in that the coating comprises solid materials consisting of 46 to 92 percent of basic filler and 8 to 54 percent of composite binder, and water which is 0.5 to 20 folds of the weight of the solid materials. The basic filler comprises several chemical components selected from silicon dioxide, alumina, magnesia, calcium oxide and boric oxide. The composite binder consists of several components selected from sodium silicate, lithium metasilicate and aluminum phosphate. The coating can be painted at the normal temperature or sprayed onto the surface of a stainless steel billet from the room temperature to 1,000 DEG C. The coating can form a protective coat at the high temperature, thereby greatly reducing the high temperature oxidation burning loss of stainless steel at 1,400 DEG C, and reducing the unit area oxidation burning loss by more than 90 percent. After stainless steel is drawn out of the furnace, the iron oxide scale can be fully stripped off under the actions of temperature reduction or high pressure water; the amount of the produced iron oxide scale is also obviously reduced; and the stainless steel surface quality is remarkably improved.

Method for rapid synthesis of aluminum orthophosphate salt polyalcohol

InactiveCN101172596AProduction Method AdvantagesShort synthesis timePhosphorus compoundsMicrowave ovenPhosphoric acid
The invention discloses a method for rapidly synthesizing aluminum phosphate salt polymeric compound. The method is characterized in that the mixture of phosphoric acid and aluminum hydroxide reacts and the mixture is synthesized under microwave condition. The method comprises the following steps: the phosphoric acid and the aluminum hydroxide are added with water to be mixed and stirred uniformly according to mol ratio; the mixture after being stirred uniformly is put into a microwave oven, and the defrosting and heating mode is selected to radiate the mixture; 750 W is selected to heat the mixture; white aluminum tripolyphosphate powder is gotten through hydrating, drying and grinding. The aluminum tripolyphosphate powder product is put into the microwave oven again to be radiated with 900 W power, and aluminum metaphosphate powder is gotten. The method integrates the reaction and polymerization of the prior art, reduces the composition time, saves the energy and the equipment, and improves the production efficiency. Because of the penetrating action of the microwave, the composition is not limited by the material quantity, and the synthetic ratio of the aluminum tripolyphosphate and the aluminum metaphosphate is improved. Related equipment can be adopted during the industrial production to realize continuous scale production.
