The results were as follows:Afterthe NH_4Y zeolite was dealuminated with Oxalic acid,the conversion of pinenespeeded up markedly, but the selectivity of camphene also dropped downmarkedly.After the NH_4Y zeolite was infused in solution of Mg(NO_3)_2,Zn(NO_3)_2 or Al(NO_3)_3 to remove corresponding oxide,the conversion rate of pinenedropped down,and the selectivity of camphene had little increase.

结果表明：NH_4Y型沸石分子筛经草酸脱铝后，蒎烯转化显著加快，但莰烯的选择性也显著下降；而NH_4Y型沸石分子筛经硝酸镁、硝酸(来源：caAB3aC论文网www.abclunwen.com)锌、硝酸铝溶液浸渍来负载相应的氧化物后，蒎烯转化率有所下降，莰烯选择性稍有增加。
