description: The reusability of silica-titania catalyst on biodiesel production from waste cooking oil in various of  catalyst loading has been investigated. The reused silica-titania catalyst has been obtained by washing  the previous catalyst used in biodiesel production from palm and waste cooking oils based on various  of catalysts loading. The DR UV-Vis has been used for characterization of reused silica-titania  catalyst to investigate the existence of titanium tetrahedral coordination in that given catalyst. In order  to get information about the catalytic activity of reused silica-titania catalyst, several analyses were  carried out on biodiesel products such as density, flow rate and acid number, as well as FTIR for  characterization. The results show that the fraction of titanium tetrahedral coordination decreased after  silica-titania catalyst reused in reaction of transesterification between waste cooking oil and methanol.  The decrease of titanium tetrahedral fraction in reused silica-titania catalyst yields a reduction in its  catalytic activity in biodiesel production. The density, flow rate, and acid number analyses show the  7% of catalyst loading was the optimum condition for biodiesel production from palm and waste  cooking oils using reused silica-titania catalyst. The FTIR spectra of biodiesel products are almost  similar to that of waste cooking oil, however, there is dissimilarity on band area in the wave number  range of 1250–1000 cm-1 attributed to vibration of C–O–C or C–O–H.
