“…Due to the demonstrated and promising results of using clay for biodiesel production, Jaimasith and Phiyanalinmat (2007) selected it as a catalyst. In a recent study, Ayoub et al, (2016) have demonstrated that montmorillonite clay K-30 is an effective catalyst for the biodiesel production from waste frying oil. Using response surface methodology,…”

“…These variables are the reaction time (minutes), reaction temperature ( o C), amount of catalyst (wt%) and oil/methanol ratio. Ayoub et al (2016) studied the effect of these four controlling variables on the biodiesel production in 30 experimental runs. Commercial clay catalyst montmorillonite K-30 (in powdered form) has been utilized in the experimental work because it has several advantages such as safe to handle, reusable, inexpensive and can act as a general acid or base.…”

“…In the current work, a fuzzy model is constructed based on the 30 experimental runs with the 4input and one-output dataset conducted by Ayoub et al (2016). During the optimization process, four operating parameters of biodiesel production process; temperature, reaction time, oil/methanol ratio and amount of catalyst were used as the decision variables.…”

AbstractTransesterification is a promising technology for the biodiesel production to provide an alternative fuel that considers the environmental concerns. From the economic and environmental protection points of view, utilization of waste frying oil for the production of biodiesel addresses very beneficial impacts. Production of higher yield of biodiesel is a challenging process in order to commercialize it with a lower cost. The current study focuses on the influence of different parameters such as reaction temperature (ºC), reaction period (min), oil to methanol ratio and amount of catalyst (wt%) on the production of biodiesel. The main objective of this work is to develop a model via fuzzy logic approach in order to maximize the biodiesel produced from waste frying oil using montmorillonite Clay K-30 as a catalyst. The optimization for the operating parameters has been performed via particle swarm optimization (PSO) approach. During the optimization process, the decision variables were represented by four different operating parameters: temperature (40-140ºC), reaction period (60-300 min), oil/methanol ratio (1:6-1:18) and amount of catalyst (1-5 wt%). The model has been validated with the experimental data and compared with the optimal results reported based on other optimization techniques. Results showed the increment of biodiesel production by 15% using the proposed strategy compared to the earlier study. The obtained biodiesel production yield reached 93.70% with the optimal parameters for a temperature at 69.66ºC, a reaction period of 300 min, oil/methanol ratio of 1:9 and an amount of catalyst of 5 wt%.

Depletion of oil reserves, increasing prices of petroleum products, and environmental concerns related to air pollution are the main driving forces for utilizing renewable energy resources to replace fossil fuels. Vegetable oils can be used to produce biodiesel. Biodiesel is obtained by transesterification of vegetable oil with alcohol using homogeneous or heterogeneous catalysts. In the industry, biodiesel is produced by heterogeneous catalysts due to high activity and selectivity, better reusability, reduction in processing steps, and wastes. The catalytic activity of catalysts depends on the strength and type of intrinsic basic or/and acid properties. Biodiesel production using heterogenous catalysts depends on the various reaction parameters such as reaction time, temperature, molar ratio of alcohol to oil, catalyst amount, and stirring speed. In this paper, the catalytic transesterification of various feedstocks such as edible oil, non‐edible oil, and waste using heterogeneous catalysts has been reviewed and optimization parameters for maximum biodiesel production have been summarized.

“…The tryglycerides react with an alcohol, usually methanol, in the presence of a basic catalyst to give alchyl esters, biodiesel, and glicerol [5,14,15]. The chemical reaction takes place in a batch stirred reactor at temperatures between 60-70 • C for a time of 60 min [5,[16][17][18]. The correct operation of the batch reactor is essential to reach a high yield of the transesterification reaction.…”

Thermal and Fluid Dynamic Analysis within a Batch Micro-Reactor for Biodiesel Production from Waste Vegetable Oil

Biofuels represent an alternative solution to petroleum-based fuels. In particular, biodiesel is very interesting, especially if it is produced from waste vegetable oil. Biodiesel can be used in diesel engines. The aim of this work is to implement a 2D numerical analysis in Comsol Multiphysics in order to verify an uniform temperature field within a non-isothermal batch mixed micro-reactor. An immersion heater system has been studied as a suitable solution to increase the temperature of WVO (Waste Vegetable Oil) before the start of the transesterification reaction. Thus, the efficiency of the immersion heating system has been investigated. The results show that the temperature field is not uniform within the fluid domain, because of the convective flux with the external environment. These conditions could lead to a low overall conversion rate.
