Small-Scale Biodiesel Production Plants—An Overview

An overview of enzymatic production of biodiesel.

Biodiesel production has received considerable attention in the recent past as a biodegradable and nonpolluting fuel. The production of biodiesel by transesterification process employing alkali catalyst has been industrially accepted for its high conversion and reaction rates. Recently, enzymatic transesterification has attracted much attention for biodiesel production as it produces high purit...

Biodiesel production from canola oil using ultrasonic reactor in small scale circulation process

Currently, most of the biodiesel is produced from vegetable oils and methanol in the presence of base catalysts using mechanical stirring method at temperature 50-65C. This method consumes much energy because oils and methanol must be heated up to desired temperature, and also requires rather long reaction time. Ultrasound-assisted reaction can reduce the reaction time much shorter than mechani...

Biodiesel Production

This article describes an in−depth follow−up to previous studies showing that an oil−methanol mixer prior to an RD reactor played an important role in enhancing the overall performance of the RD reactor system. An in−line static mixer was used for the purpose of providing initial mixing of the reactants, heating the mixture up to the desired operating temperature, and carrying out a substantial...

Biodiesel Production from Different Feedstocks in Pilot Scale System

In this study, the preparations of biodiesel from three different feedstocks, including rapeseed oil, high acidified Chinese wood oil and trap grease, were carried out in a pilot scale of 200 t yr-1 biodiesel production system. The optimum operating conditions for transesterification of rapeseed oil in plug flow reactor were found to be as follows: the catalyst dosage is 1.2 wt%; the retention ...
