英文摘要： Chiral aluminophosphate molecular sieves are prepared by Solvothermal method, rosin surfactants used as template agents. The effect of rosin surfactants optical rotation characteristics on the chiral properties of the aluminophosphate molecular sieves and the effect of different preparing conditions on the physical and chemical structures of the chiral aluminophosphate molecular sieves are studied, and the changes of their physical and chemical structure are traced, the synthesis mechanism of aluminophosphate molecular sieves are researched. The aluminophosphate molecular sieves with chiral properties are used as the support, amorphous Ni-P catalyst for the pinene selective hydrogenation are prepared by the impregnation reduction method, the impacts of catalyst structure on its catalytic activity and selectivity will be studied to obtain the relationship of catalyst preparation-structure-catalytic performance and to determine the preparation method and preparation conditions of chiral aluminophosphate molecular sieve supported Ni-P amorphous catalyst. The catalyst with excellent performance will used to catalyze selective hydrogenation of pinene, the reaction process, mechanism and kinetics will be studied, catalyst life will be studied, too. The results of the research are important to promote the study on n
