Optimization of Ni-P/APO-11 amorphous catalyst for catalytic hydrogenation of turpentine using response surface methodology

APO-11 aluminophosphate molecular sieve was prepared from diisopropylamine and calmogastrin by hydrothermal synthesis method. The amorphous catalysts Ni-P/APO-11were prepared by chemical reduction and applied in the catalytic hydrogenation of turpentine. The α-pinene hydrogenation reactions were investigated and optimized by response surface methodology, meanwhile, amorphous catalysts were characterized by XRD, BET, SEM, XPS, and ICP. Under reaction temperature 124.8℃, reaction pressure 4.9 MPa, catalyst amount 6.3%, and reaction time 90 minutes, the conversion rate of α-pinene was 99.45%, the selectivity of cis-pinane was 97.35%. Meanwhile, the catalysts were used in catalytic hydrogenation of other components to broaden the range of catalysts and improve deep process of turpentine, the catalysts exhibited high catalytic activity, raw conversion was reached more than 99%, and the selectivity was reached more than 65%.
