Catalytic Activity of Zr4+/ZA on The Isomerization Reaction of α-Pinene and It’s Reusability Test

Abstract

Production of turpentine oil from pine resin until December 2014^th was reported to reaching 17.150 tones with the wide of pine forest is 876.992,66 acres. The main component of turpentine oil is α-pinena which isomer products have high value for industrial raw materials. Effects concentration of impregnation and reusability test a best catalyst on α-pinene isomerization reaction using catalysts Zr⁴⁺/natural zeolite in which modificated with different Zr⁴⁺ concentration were analyzed. Characterization of catalyst included X-ray Fluoroscent for detection of Zr concentration in natural zeolites, Surface Area Analyzer  for determine catalyst porosity using BET method, and determination of acidity using vapor ammonia and pyridine base adsorption gravimetric method. Isomerization process used a batch reactor with variation in the concentrations of Zr⁴⁺ impregnations 10, 15, and 20 w/w as well as reusability test used best catalyst. The highest conversion of α-pinene  used Zr⁴⁺/ZA 10% catalyst was 3,89% so as Zr⁴⁺/ZA 10% catalyst is best catalyst than other catalysts whereas highest conversion of α-pinene used Zr⁴⁺/ZA 10% regeneration catalyst was 4,26%. The product is produced from isomerization reaction of α-pinene used Zr⁴⁺/ZA all variations catalysts was camphene and limonene.
