Successive Optimisation of Waste Cooking Oil Transesterification in a Continuous Microwave Assisted Reactor

Successive Optimisation of Waste Cooking Oil Transesterification in a Continuous Microwave Assisted Reactor

This paper presents an optimization study of waste cooking oil (WCO) transesterification in a continuous microwave assisted reactor (CMAR). The custom-built CMAR employed an integrated proportional-integral-derivative controller for accurate control of temperature and reactant flowrate. The fatty ac...
