Role of plasma assistance on the catalytic transesterification process of methanol and triglyceride to produce biodiesel plasma.

Treatments	Yield of biodiesel (%)	Space time (min)
Catalytic transesterification without plasma(a)	49.8	1.25
Catalytic transesterification using plasma (hybrid) (b)	77.2	1.25

(a) Condition: methanol:oil ratio of 15:1, voltage of 1.5 kV, WHSV of 1.186/min, and diameter of catalyst pellet of 5 mm.

(b) Condition: methanol:oil ratio of 15:1, WHSV of 1.186/min, and diameter of catalyst pellet of 5 mm.
