A comparative study of biodiesel pr

A comparative study of biodiesel production from waste cooking oil using sulfuric acid (Two-step) and microwave-assisted transesterification (One-step) was carried out. A two-step transesterification process was used to produce biodiesel (alkyl ester) from high free fatty acid (FFA) waste cooking oil. Microwave-assisted catalytic transesterification using BaO and KOH was evaluated for the efficacy of microwave irradiation in biodiesel production from waste cooking oil. On the basis of energy consumptions for waste cooking oil (WCO) transesterification by both conventional heating and microwave-heating methods evaluated in this study, it was estimated that the microwave-heating method consumes less than 10% of the energy to achieve the same yield as the conventional heating method for given experimental conditions. The thermal stability of waste cooking oil and biodiesel was assessed by thermogravimetric analysis (TGA). The analysis of different oil properties, fuel properties and process parametric evaluative studies of waste cooking oil are presented in detail. The fuel properties of biodiesel produced were compared with American Society for Testing and Materials (ASTM) standards for biodiesel and regular diesel.

'N Vergelykende studie van biodiesel produksie van afval kookolie gebruik van swaelsuur (Two-step) en mikrogolf bygestaan ​​transesterifikasie (Een-stap) is uitgevoer. 'N twee-stap transesterifikasie proses is gebruik om biodiesel (alkiel ester) van 'n hoë vry vetsuur (FFA) afval kookolie vervaardig. Mikrogolf-bygestaan ​​katalitiese transesterifikasie behulp Bao en KOH is geëvalueer vir die doeltreffendheid van die mikrogolf bestraling in biodiesel produksie van afval kookolie. Op grond van energie verbruik vir afval kookolie (WCO) transesterifikasie deur beide die konvensionele verhitting en mikrogolf-verwarming metodes geëvalueer in hierdie studie, is dit beraam dat die mikrogolf-verwarming metode verbruik minder as 10% van die energie om dieselfde opbrengs te bereik as die konvensionele verhitting metode vir gegewe eksperimentele toestande. Die termiese stabiliteit van afval kookolie en biodiesel is beoordeel deur termo-analise (TGA). Die ontleding van verskillende olie eienskappe, brandstof eienskappe en proses parametriese evaluerende studie van afval kookolie word in detail. Die brandstof eienskappe van biodiesel vervaardig is in vergelyking met die Amerikaanse Vereniging vir Toetsing en Materiale (ASTM) standaarde vir biodiesel en gereelde diesel.
