PEMBUATAN DAN KARAKTERISASI KATALIS HETEROGEN SO42- ZNO DAN SO42- / ZNO DENGAN METODE KOPRESIPITASI DAN IMPREGNASI UNTUK PRODUKSI BIODIESEL DARI MINYAK KEDELAI
ABSTRACT: In this reasearch
focuses on the physical and chemical 2- characterization of 2- sulfated zinc
oxide catalyst SO4 - ZnO with coprecipitation method and SO4 / ZnO impregnation
method. The purpose of this study is to prepare the ZnO-based acid catalyst, to
determine the characteristics of the catalyst, and the catalyst testin on
biodiesel production from soybean oil. The characterization was conducted using
X-ray diffraction (XRD) to determine the catalyst morphology and Fourier
Transform-Infra Red (FT-IR) to determine the structure of chemical bonds are
formed. Identification of the content and composition of biodiesel, mainly on
the composition of Fatty Acid Methyl Ester (FAME), were analyzed by GC-MS and
by FT-IR. Meanwhile the heat content of the products of 2- biodiesel calorific
value is measured. Results of the characterization showe that the SO4 2- - ZnO
catalyst has a stronger acidity and higher catalyst activity than acidic SO4 /
ZnO catalysts. In the catalyst testing for the transesterification process, the
SO42--ZnO catalyst showed the biodiesel yield of 80.19%.
