“…It has been reported that, an increase in the reaction temperature and alcohol/oil molar ratio lowered the biodiesel yield due to the evaporation of alcohol. Moreover, other researchers have investigated the effect of alcohols on transesterification reaction for the production of biodiesel [27]. It has been concluded that higher alcohols have lesser reactivity so need more catalyst and higher temperature to speed up the reaction.…”

Biodiesel is an attractive alternative fuel for diesel engines produced from vegetable oils or animal fats by transesterification in the presence of a catalyst. The feedstocks used in this experiment for the production of biodiesel were waste frying oil (WFME) waste canola oil (WCME), and their different percentages are referred to as 25-WFME, 50-WFME and 75-WFME. The samples are sourced from Northern Cyprus. Also, biodiesel was produced at Mechanical Engineering research laboratory. The purpose of this study is to investigate the effect of the temperature on the kinematic, dynamic viscosity and density of the biodiesel samples. Also, this paper examines the cold flow properties as well as the kinematic viscosity, cloud point (CP) and pour point (PP) of the produced biodiesel. The density, kinematic viscosity, CP and PP measurements were made according to ASTM standards. The properties of the produced biodiesel such as viscosity and density were measured within temperature ranges 20-270°C in steps of 10°C. The kinematic viscosity, CP and PP were measured within temperature range -10-20°C. In this study, five general correlations were presented for estimating the density and kinematic viscosity of the blends at several temperatures. The experimental investigation showed that CP and PP of WCME increased with an increase in the concentration of WFME. Furthermore, empirical equations for predicting the viscosity, density, CP and PP for biodiesel samples give values in good agreement with experiments. The results obtained show that with the increase of the temperature, kinematic viscosity, dynamic viscosity and density decreased.

“…The methyl ester was washed three times using distilled water and the layers of oil from methanol and H 2 SO 4 were separated. The pre-treated oil was heated up to 100 ℃ to remove excess water content [34][35][36][37][38][39].…”

Active calcium oxide catalyst was synthesised from Meretrix Lyrata (M.Lyrata) following calcination-hydration-dehydration technique. The catalytic feasibility of synthesised CaO was investigated in the production of Karanja methyl ester (KME) from crude Karanja oil (CKO). KME was synthesised through esterification using followed by transesterification utilising CaO in a two-step reaction process of CKO and methanol. The M.Lyrata shells were calcined at 900 ℃ and the catalyst samples were characterised using FTIR, SEM, PSA, and BET-BJH spectrographic techniques. A maximum fatty acid methyl ester (FAME) conversion of 97.3 % was obtained at optimum reaction conditions including methanol-to-oil ratio of 12:1, catalyst concentration of 2 wt.%, reaction temperature of 58 ℃ and reaction time of 2 hrs. In a comparative study with commercial CaO, M.Lyrata showed a higher catalytic activity. The catalyst reusability experiments ascertaining reusability of CaO up to four reuse cycles had shown good efficiency. The economic comparative study confirms that CaO derived from M.Lyrata can be used as an alternative and feasible catalyst for biodiesel production. The KME fuel properties complied to EN-14214 biodiesel fuel standards.
