Recovery of Diesel-Like Fuel from Waste Palm Oil by Pyrolysis using a Microwave Heated Bed of Activated Carbon

Microwave pyrolysis using a well-mixed bed of activated carbon as both the microwave absorber and reaction bed was investigated for its potential to recover useful products from waste palm cooking oil - a cooking oil widely used in Asia. The carbon bed provided rapid heating (~18 C/min) and a locali...
