As the calorific value of vegetable oils is comparable to that of diesel, they could be used as fuels in compression ignition engines [ 1 ].
The synthesis of biodiesel expressed as fatty acid methyl ester FAME were studied to achieve an economic and practical method for utilization of used cooking oil UCO. These ILs show good catalytic activity for the transeserification of tung oil.
In addition, these ionic liquids had a good reusability and could be easily separated from the biodiesel. This paper introduced a better solution to accelerating the production of biodiesel from waste cooking oil by using suitable acidic and alkaline catalysts in a two-stage catalytic reaction.
Next, a co-solvent named tetrahydrofuran THFwhich significantly increased mixing level of the reactants in the mixture of vegetable oil and methanol, was added to form a single phase system. The whole system was then put into a microwave oven to support heat for the transesterification of biodiesel to shorten the reaction time.
Reaction conditions of the first stage were methanol to oil molar ratio of 9: In the second stage, for the transesterification, reaction conditions were methanol to oil molar ratio Finally, the conversion rate of biodiesel after the nine-minute reaction time was Yuan Dong Xu Abstract: Two different ionic liquid of the N- 3-sulfonic group propyl pyrrolidone hydrosulfate [C3SO3Hnhp]HSO4 and the 2-pyrrolidone hydrosulfate [Hnhp]HSO4 have been synthesized and used as catalyst for the biodiesel production from the soybean oil.
The former exhibited better catalytic performance than that of the later one and the reaction conditions corresponding to [C3SO3Hnhp]HSO4 were optimized. Under the optimal condition the yield of methyl ester reached The influence of various reaction variables on the conversion was investigated.Biodiesel production process.
The collected waste cooking oil was purified and dried from moisture. The required amount of waste cooking oil was taken in a three-necked flask equipped with a reflux condenser and cool-water chiller.

Biodiesel from waste cooking oil 1. Biodiesel: Fuel For Next Generation By: Akshay Patil Roll no 2. QUICK RECAP What is Biodiesel? Properties Advantages/Disadvantages Uses Preparation of Biodiesel Heat ml of the oil at 60o C to remove moisture content, by using heating mantle.
Add NaOH into ml of . The preparation of biodiesel from waste cooking oil is cheap and the source is conveniently available from restaurant and hotel.
Biodiesel is prepared from the trans esterification process which involves two step- acidic esterification in which oil (1litre), solution of sulphuric acid and methanol is heated at 60° C forhours at rpm and. trucks. Biodiesel can be used directly in diesel engines or blended with petroleum based diesel fuel.
Vegetable oils are esters of glycerin, commonly called triglycerides, with different fatty acids with the structure: I 2 II III 2 O HC O C R O HC O C R O HC O C R.
