| 1 | Experimental modeling of polymer latex spray coating for producing controlled-release urea显示文摘Spray coating of polymer latex onto fertilizer particles in a fluidized bed for producing controlled-release urea is an environment friendly technology as it does not need any toxic organic solvent. Since the spray coating process in a fluidized bed occurs in the presence of particle collisions, the coating of the particles is random, intermittent and multiple, thus making it difficult to investigate the film formation process. In this paper, an experimental model apparatus was designed and used to investigate the effects of the key factors in the spray coating process. This apparatus reasonably simplified the complex process to avoid particle collisions and randomness in the coating. The intermittent coating in the fluidized bed was modeled by periodic coating and dewatering in the experimental apparatus. A large area film was obtained, and the film permeability was measured. The effects of atomizing gas flow rate, spray rate of latex, solid content of latex and gas temperature on film structure and film permeability were investigated. It was found that water transfer played a dominant role in the spray coating process. | Rui Lan Yonghui Liu Guanda Wang Tingjie Wang Chengyou Kan Yong Jin | 2011 | Particuology2011，9，5： | 6 |
| 2 | Granulation by spray coating aqueous solution of ammonium sulfate to produce large spherical granules in a fluidized bed显示文摘Spherical 2-4mm granules of ammonium sulfate(NH_4)_2SO_4 are promising fertilizer for practical use,though only much smaller grains are being produced in industry.This work used coating granulation to produce large spherical granules of(NH_4)_2SO_4 in a fluidized bed by spraying its aqueous solution onto0.9-1.6 mm(NH_4)_2SO_4 core particles.However,the overall coating efficiency was only 58%due to loss as dust by attrition of(NH_4)_2SO_4 in the vent gas.By adding CaCO_3 or SiO_2 particles into the feed solution,the coating efficiency was increased to over 90%.This increase in coating efficiency was due to a change in the crystallization mechanism of(NH_4)_2SO_4.The added CaCO_3 or SiO_2 particles provided a heterogeneous surface that induced(NH_4)_2SO_4 to crystallize uniformly to form a more compact structure less susceptible to attrition. | Guanda Wang Ling Yang Rui Lan Tingjie Wang Yong Jin | 2013 | Particuology2013，11，5： | 5 |
| 3 | Hybrid structure of iron single atoms and metallic titanium for photothermal ethanol steam reforming显示文摘Photothermal ethanol steam reforming(ESR) is currently limited by low intrinsic activity and strong solar energy dissipation.Herein,we synthesized Fe single atoms supported on CeO_(2)(SA Fe-CeO_(2)) to exhibit excellent low-temperature ESR activity with a hydrogen production rate of 512 mmol g^(-1)h^(-1) at 350℃,becuase of the high oxidation state of Fe single atoms to weaken the reaction barrier of ethanol decomposition.Furthermore,a heterostructure of SA Fe-CeO_(2) and Ti foil could eliminate 66% of infrared radiation via the size effect,thus achieving a 3.5 sun-driven temperature of 347℃.Consequently,the heterostructure of SA Fe-CeO_(2) and Ti foil shows a hydrogen generation rate of 984 mmol g^(-1)h^(-1) of ESR and 11.31% of solar-to-hydrogen energy conversion efficiency,which outperforms other photothermal ethanol-hydrogen production systems.This study provides a new path for designing active catalytic sites and trapping light energy of photothermal catalysts. | Dachao Yuan Guanda Han Zhixuan Wang Jianguo Zhao Kailuan Li Pengfei Wang Jianjun Hao Yaguang Li Jinhua Ye | 2024 | Science China Chemistry2024，67，3： | 0 |
