Publication number: 20210023833Abstract: A preparation system and preparation method for a gel composite material. Periodic impregnation can be performed and the gel composite material product performed gelation can be rewound and recycled by moving a movable impregnation mechanism back and forth along an impregnation platform; specifically, during the process that the movable impregnation mechanism moves from the front end to the rear end of the impregnation platform, a first unwinding device can be controlled to lay a reinforcing body to be impregnated on a worktable, the impregnation device can be controlled to guide the prefabricated sol onto the reinforcing body to be impregnated, and a second unwinding device can be controlled to cover a covering carrier on an upper surface of the impregnated reinforcing body; when the movable impregnation mechanism moves to the rear end of the impregnation platform, the first unwinding device, the impregnation device, and the second unwinding device can be controlled to stop.Type: ApplicationFiled: March 30, 2018Publication date: January 28, 2021Inventors: Ronghui WEI, Qiuhua ZHANG, Ping LIU, Liangbo RAO

Patent number: 10532350Abstract: A method for synthesizing small crystals of silicoaluminophosphate-34 (SAPO-34) molecular sieves with high structural purity. The method includes first forming a slurry comprising monoisopropanolamine. Then, the slurry is aged to form an aged slurry. Finally, crystallization of silicoaluminophosphate molecular sieves comprising the SAPO-34 molecular sieves is induced from the aged slurry.Type: GrantFiled: August 21, 2015Date of Patent: January 14, 2020Assignee: W.R.

Patent number: 9889440Abstract: A method for synthesizing small crystals of silicoaluminophosphate-34 (SAPO-34) molecular sieves with high structural purity. The method includes forming a first slurry and a second slurry which are aged separately to form a first aged slurry and a second aged slurry. The first slurry includes a first source of phosphorus, a first source of aluminium, a first source of silicon, and at least one first organic structure directing agent. The second slurry includes a second source of phosphorus, a second source of aluminium, a second source of silicon, and at least one second organic structure directing agent. Then, the first aged slurry and the second aged slurry are combined to form a mixture of aged slurries. Finally, crystallization of silicoaluminophosphate molecular sieves comprising the SAPO-34 molecular sieves is induced from the mixture of aged slurries.Type: GrantFiled: October 23, 2014Date of Patent: February 13, 2018Assignee: W.R.

Publication number: 20090148377Abstract: The present invention relates to a method for preparing a lithium vanadium phosphate material comprising mixing water, lithium dihydrogen phosphate, V2O3 and a source of carbon to produce a first slurry; wet blending the first slurry; spray drying the wet blended slurry to form a precursor composition; milling the precursor composition to obtain a milled precursor composition; compacting the milled precursor to obtain a compacted precursor; pre-baking the compacted precursor composition to obtain a precursor composition with low moisture content; and calcining the precursor composition with low moisture content at a time and temperature sufficient to produce a lithium vanadium phosphate. The lithium vanadium phosphate so produced can optionally be further milled to obtain the desired particle size. The electrochemically active lithium vanadium phosphate so produced is useful in making electrodes and batteries and more specifically is useful in producing cathode materials for electrochemical cells.Type: ApplicationFiled: December 11, 2007Publication date: June 11, 2009Inventors: Ralph E.

Patent number: 7014837Abstract: Described is a process to synthesize nano-size Zeolite A from an amorphous gel precursor which can be synthesized via reaction of NaAlO2, NaOH, and tetraethoxysilane (TEOS). Zeolite A with particle sizes of ˜150 nm was made by transformation of the amorphous precursor in (CH3)4NOH solution with Zeolite A seeding. The nano-sized Zeolite A can be part of processes for making non-phosphate detergent where the as-synthesized Zeolite A used as builders, for making thin films for separation and/or catalysis, for making secondary ordered patterns.Type: GrantFiled: September 16, 2003Date of Patent: March 21, 2006Assignees: E.
