This study is initiated to develop a composite catalyst from naturally occurring and waste materials. The catalyst preparation conditions which include activation temperature (600-1000oC) activation time (2-4 h) and mixing proportion of anthill to eggshell (1:1.5-1:4) were investigated using central composite design (CCD) of response surface methodology (RSM) in design expertsoftware. A model that correlates the three process parameters to the response (biodiesel yield) was established. The model reliability was evaluated using analysis of variance (ANOVA). The catalyst prepared under the optimum conditions was characterized using scanning electron microscopy (SEM) Fourier transform infrared radiation (FTIR) spectroscopy and X-ray Diffraction (XRD) technique. From the ANOVA both the predicted and experimental biodiesel yields agreed well with each other with correlation coefficient of 0.9806. The optimum composite anthill-eggshell catalyst preparation conditions were obtained as follow activation temperature of 1000oC 4 h activation time and anthill/eggshell mixing ratio of 1:4 which provided biodiesel yield of 70.92.

Abstract

This study is initiated to develop a composite catalyst from naturally occurring and waste materials. The catalyst preparation conditions which include activation temperature (600-1000oC) activation time (2-4 h) and mixing proportion of anthill to eggshell (1:1.5-1:4) were investigated using central composite design (CCD) of response surface methodology (RSM) in design expertsoftware. A model that correlates the three process parameters to the response (biodiesel yield) was established. The model reliability was evaluated using analysis of variance (ANOVA). The catalyst prepared under the optimum conditions was characterized using scanning electron microscopy (SEM) Fourier transform infrared radiation (FTIR) spectroscopy and X-ray Diffraction (XRD) technique. From the ANOVA both the predicted and experimental biodiesel yields agreed well with each other with correlation coefficient of 0.9806. The optimum composite anthill-eggshell catalyst preparation conditions were obtained as follow activation temperature of 1000oC 4 h activation time and anthill/eggshell mixing ratio of 1:4 which provided biodiesel yield of 70.92.
