Acceleration in biodiesel production from palm oil process by high voltage electric field

Abstract

This article aims to introduce an innovative method of acceleration in biodiesel production process. The biodiesel was produced from fatty acids, using palm oil that is widely used in food industry as a raw material. Methyl alcohol is a solvent with a molar ratio of 1:6 and using potassium hydroxide (KOH) as catalyst at 1 wt. %. The reaction of biodiesel production was prepared by 100 ml substrate and conducted in the reactor chamber. The chamber was custom built with coaxial cylindrical electrode consisted of inner rod electrode and outer tube electrode. Supply high voltage levels were at 1, 2.5 and 5 kV and exposure time was selected for 5, 10, 15 and 20 minutes to compare with the controlled sample without electric field. It is found that; electric field can rapidly accelerate the rate of reaction on biodiesel production. Glycerine settling resulting from electric field stress is significantly much faster than conventional sedimentation by gravity method. If electric field stresses is increased, the rate of reaction is also faster. It was also notice that, the higher glycerine content was achieved when applying voltage is increased in the same direction. The electric field stresses that produce the highest glycerine yield is at 5 kV. It can also be noticed that, at 5 kV the rate of glycerol settling content were retarded at 15-20 minutes, which is found to be the saturation point of reaction.

Biodiesel production from palm olein: A sustainable bioresource for Nigeria

“…Transesterification involves the conversion of the fatty acids chain of triglyceride molecules found in oil samples into ethyl or methyl esters in the presence of an alcohol and catalyst mixture (Folayan et al, 2019). The ASTM (American Society for Testing and Materials Standard) describes the mono-alkyl esters of fatty acids with long chains formed from the transesterification process as Biodiesel (Carlos et al, 2011;Ratanabuntha et al, 2018). Generally, the efficacy of converting oil to biodiesel through transesterification process depends on (i) reaction time, (ii) reaction temperature, (iii) ratio of alcohol to oil and (iv) the quantity of the catalyst (Abbah et al, 2016;Yusuff et al, 2019).…”

Separación Electrostática de una Emulsión de Glicerina en Biodiésel con Aplicación de Varios Voltajes y Distancias entre Electrodos

“…En cambio, para un voltaje de 3000 V y una distancia entre electrodos de 6 cm se logró la misma separación en un tiempo de 45,3 segundos. En los últimos años han aparecido en la bibliografía muy pocos trabajos de varios autores que utilizan esta técnica para purificar biodiésel obtenido de fuentes diversas (Abbaszadeh et al, 2013, 2014; Barakat y Mayer-Laigle, 2017; Ratanabuntha et al, 2018;Susumu, 2018;Trisnaliani y Zikri, 2018;Utama Putra et al, 2018;Xie et al, 2011). En la mayoría de los trabajos no se da información detallada de cómo llevan a cabo los procesos.…”

Karakteristik Sifat Fisika Kimia Biodiesel Berbasis Minyak Nabati

“…Setelah dipanaskan dan diaduk selama 1 jam, minyak dimasukkan ke dalam tabung pemisah untuk tahap settling (Gambar 6). Proses settling pada pemurnian biodiesel bertujuan untuk mengurangi kadar gliserol bebas yang masih terikat pada metil ester (Ratanabuntha et al, 2018).…”
