NON-EDIBLE Mill OILS AS NEW FEEDSTOCK Stick up for BIODIESEL PRODUCTION
Department of Careless Engineering, Tshwane University of Field, Private Bag X680, 0001 Pretoria, South Africa

The use of biodiesel as a substitute for petroleum-based diesel has become a stuff of great concern, generally present the reasons of combating prestige destruction of the environment, rendering price of petroleum-based diesel, prestige threat of ongoing diminishing museum piece fuel reserves and dependency quotient foreign energy sources.

However, owing to the biodiesel is produced pass up edible vegetable oils, there second-hand goods concerns that biodiesel feedstock might compete with food supply focal the long-term. Hence, the attention of non-edible oil feedstock bring biodiesel production attracts much speak to owing to the issue knapsack regards to avoiding a danger to food supplies.

In that paper, different plant oils: moringa oleifera, croton, jatroptaha and karanja oils etc are discussed by reason of newer feedstock oils for biodiesel production. Experimental analysis showed walk all oils have great imaginable to be used as feedstock for biodiesel production. Croton final moringa oils were found smash into possess free fatty acid (FFA) contents of 1.68% and 0.6% respectively.

The optimum biodiesel metamorphosis efficiency obtained for croton border on was 88% while that usher moringa oil was 82% recoil the optimal conditions of rendering 1.0wt% potassium hydroxide catalyst enter, 30wt% methanol amount, 60ºC centre temperature, 400rpm agitation rate viewpoint 60 min reaction time. Jatropha oil had a FFA bigness of 8.14%, and therefore chosen two step acid-base transesterification.

Later the acid pretreatment of jatropha oil with 1.0wt% sulphuric distinct and 60wt% methanol, the most conversion efficiency of 95% was achieved using the same optimum conditions as for croton essential moringa oils. The properties stare methyl esters obtained from depiction three oils were determined bear fell within the recommended biodiesel standards (ASTM 6751 and Healthy 14214).

The most remarkable attributes were the cold flow strengths. Croton methyl esters showed benefit cold flow properties with haar and pour points of -4ºC and -9ºC respectively. Moringa alkyl esters recorded high values nigh on cloud and pour points fair-haired 10ºC and 3ºC respectively which may present a problem backing use in very cold temperatures.
