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<sup>th</sup> 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 Zr<sup>4+</sup>/natural zeolite in which modificated with different Zr<sup>4+</sup> concentration were analyzed. Characterization of catalyst included <em>X-ray Fluoroscent </em>for detection of Zr concentration in natural zeolites, <em>Surface Area Analyzer </em> 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 Zr<sup>4+</sup> impregnations 10, 15, and 20 w/w as well as reusability test used best catalyst. The highest conversion of α-pinene used Zr<sup>4+</sup>/ZA 10% catalyst was 3,89% so as Zr<sup>4+</sup>/ZA 10% catalyst is best catalyst than other catalysts whereas highest conversion of α-pinene used Zr<sup>4+</sup>/ZA 10% regeneration catalyst was 4,26%. The product is produced from isomerization reaction of α-pinene used Zr<sup>4+</sup>/ZA all variations catalysts was camphene and limonene.
