Regression analysis on the stability of surfactant mixed-MoO3 nanoparticles dispersed Gossypium arboretum biodiesel

Abstract

ABSTRACT The stability, physicochemical characteristics, molybdenum trioxide (MoO3) nanoparticles in Gossypium arboretum biodiesel (BD20), and deduction of the regression equation for parameters governing the stability of biodiesel are the main subjects of this study. With and without the surfactant Cetyltrimethylammonium Bromide (CTAB), MoO3 nano additions were combined with BD20 at 60, 80, and 100 ppm concentrations. A spectrophotometer that measures the samples’ absorbance and transmittance was used to examine the stability of nano fuels on days 1, 10, and 20. CTAB mixed nano samples demonstrated high stability and enhanced essential fuel qualities when compared to basic nano fuels. The fuel BD20MoO380CTAB80 (BD20+ MoO3 80 ppm+ CTAB 80 ppm) showed a decreased transmittance of 88.3% and a higher absorbance of 4.3 AU.BD20MoO380CTAB80 recorded a higher value of Cetane number of 64 and a heating value of 41,238 kJ/kg. Physicochemical properties such as Kinematic Viscosity and Relative Density recorded lower values of 4.23 cSt and 880 kg/m3. Linear regression is applied to the obtained absorbance and transmittance values.
