Abstract
The isomerization reaction of a-pinene from turpentine oil using heterogeneous catalysts (Zr4+/natural zeolite) produces monocyclic and bicyclic compounds and other products. The purpose of this study is to investigate the effects of time, concentration of Zr4+ and temperature on the activity and selectivity of the catalyst. Catalyzed reactions in heterogeneous phases were performed. In heterogeneous reaction, catalyst Zr4+/natural zeolite at several temperatures were used. Results indicate that the modification of the catalyst by cation Zr4+ increases the acidity from 2.76 to 6.64 mmol/g. It can be observed that conversions and selectivities have been explained in terms of surface acidity, structural and textural features of the modified natural zeolite determined by using X-ray diffraction and N2 adsorption at 77 K. FT-IR spectra of adsorbed pyridine on catalysts Zr4+/natural zeolite show the presence of Lewis and Brönsted acid sites.
