Abstract

Natural zeolite in Indonesia generally divided into 2 types, which are mordernite and clinoptilolite. As far the use of zeolites is very limited. This experiment tries to use both types of natural zeolites to find out its work. The purpose of this experiment is testing the performance of mordenite natural zeolite from Bayah-Indonesia and clinoptilolite from Lampung- Indonesia in the esterification reaction between glycerol and oleic acid integrated by several variable that affect the reaction. The experiment will be done by using three-neck rounded flask batch reactor. The result showed that modernite zeolite has a better performance compared to clinoptilolite zeolite. To get the oleic acid conversion of 70%, clinoptilolite zeolite needs 4% catalyst of glycerol weight and reactant ratio of 6:1 mole of glycerol/mole of oleic acid, Meanwhile the mordernite zeolite only needs 2% catalyst of glycerol weight with reactant ratio of 4:1 mole of glycerol/mole of oleic acid.Keywords: natural zeolite; glycerol; reaction; diffusion

Abstract

Biooil is the main product in the pyrolysis process which is expected to be a liquid fuel replacement solution. But the resulting biooil cannot be directly used as a result of high oxygenated compounds, high viscosity, corrosive, and unstable. Addition of activated natural zeolite catalyst to the pyrolysis process is expected to improve the quality of biooil in order to be used as a renewable liquid fuel. The research aims to determine the influence of acid concentrations on zeolite modification to the characteristics of pyrolysis products. Result of catalyst characterization indicates that zeolite activation using acid will increase Si/Al ratio as well as open the surface of previously hindered zeolite. The yield of char produced in this study tends not to undergo significant changes between the catalytic and noncatalytic pyrolysis by 33% wt. Addition of zeolite catalyst in pyrolysis proved to be able to increase the content of phenol and decrease the content of acetic acid in bio-oil by 6% . Meanwhile, yield of CO2 increases by 20% in the use of catalysts due to the release of oxygen in the oxygenate compounds. The results of this study showed that the resulting biooil still does not meet the specifications of liquid fuels but can be utilized as a renewable chemical feedstock.Keywords: pyrolysis; biomass; natural zeolite;modified
