Abstract

Biodiesel fuel is one of the types of liquid fuel and an alternative to petroleum diesel fuel in internal combustion machines. The current study is among many previous studies in which different types of biodiesel fuel were prepared and analyzed using local and inedible oils, vegetable and animal oils. A new heterogeneous basic catalyst SrO loaded on activated carbon SrO@AC showed high catalytic performance in the trans-esterification reactions of used cooking frying oil (WFO). The best yield of 98% by weight was obtained from fatty acid methyl esters (FAME) from biodiesel fuel with specifications conforming to the American standard (ASTM D 6751 EN 14214). The best experimental conditions were obtained, which were at a catalyst concentration of 1.5% and a methanol to the oil was 1:7, the time was 60 minutes, the temperature was 60 °C, and the ratio of carbon loading to strontium oxide was (15:100). The catalyst was used for four different variables, and the nanocatalyst was diagnosed using the following spectral techniques (FTIR, SEM, EDX-mapping, BET, TEM, ) Biodiesel fuel was produced and the fuel was identified by spectral techniques (HNMR, TLC) and its physical and chemical properties were studied in terms of density, viscosity and acid number of the frying oil, which was (0.926, 2.1mgKOH/gm, 40.2).
