Abstract: A method that can effectively increase the transesterification conversion of oils comprises the following steps of setting a rotating packed bed reactor for performing centrifugal rotation, centrifugally rotating the rotating packed bed to rotate relative to the container by the drive shaft; heating the oils and additives being heated to arrive at a temperature range approximately between 40 degrees Celsius to 100 degrees Celsius before entering the rotating packed bed; injecting the oils and the additives; performing the transesterification reaction, wherein the oils and the additives are delivered by a centrifugal force to pass through the stainless steel filler in the packed reaction region; performing the transesterification reaction with a rotation speed range of approximately 300 rpm to 1500 rpm; inducing a phase separation; and collecting the effluent at the outlet of the rotating packed bed reactor.

Abstract: A method of increasing transesterification conversion of oils includes steps of packing a filler into a rotating packed bed reactor having a rotary bed, centrifugally rotating the rotary bed, injecting an oil into the rotary bed, performing transesterification with adding a reaction gas into the rotating packed bed reactor and collecting the modified oil. By centrifugally rotating the rotary bed, the oil is provided with kinetic energy to pass through the filler and transesterification conversion of the oil is raised. Therefore, manufacturing costs can be lowered and the oil is modified to become suitable fuel for automobiles or motorcycles.
