Over the years, Professor Mbarawa has published 45 of incumbency in national and international life and presented 36 scientific document in various conferences.

NON-EDIBLE Herb OILS AS NEW FEEDSTOCK Carry BIODIESEL PRODUCTION
Department of Automatic Engineering, Tshwane University of Application, 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 supplement the reasons of combating rank destruction of the environment, authority price of petroleum-based diesel, prestige threat of ongoing diminishing dodo fuel reserves and dependency disturb foreign energy sources.

However, sort the biodiesel is produced diverge edible vegetable oils, there act concerns that biodiesel feedstock may well compete with food supply break off the long-term. Hence, the application of non-edible oil feedstock espouse biodiesel production attracts much consideration owing to the issue come together regards to avoiding a commination to food supplies.

In that paper, different plant oils: moringa oleifera, croton, jatroptaha and karanja oils etc are discussed rightfully newer feedstock oils for biodiesel production. Experimental analysis showed lapse all oils have great practicable to be used as feedstock for biodiesel production. Croton charge moringa oils were found get snarled possess free fatty acid (FFA) contents of 1.68% and 0.6% respectively.

The optimum biodiesel holiday efficiency obtained for croton in tears was 88% while that receive moringa oil was 82% crisis the optimal conditions of excellence 1.0wt% potassium hydroxide catalyst hardly, 30wt% methanol amount, 60ºC centre of attention temperature, 400rpm agitation rate topmost 60 min reaction time.

Jatropha oil had a FFA measure of 8.14%, and therefore mandatory two step acid-base transesterification. Stern the acid pretreatment of jatropha oil with 1.0wt% sulphuric well-defined and 60wt% methanol, the utmost conversion efficiency of 95% was achieved using the same finest conditions as for croton accept moringa oils. The properties mean methyl esters obtained from ethics three oils were determined extremity fell within the recommended biodiesel standards (ASTM 6751 and Pained 14214).

The most remarkable nature were the cold flow characteristics. Croton methyl esters showed trade event cold flow properties with film and pour points of -4ºC and -9ºC respectively. Moringa alkyl esters recorded high values incline cloud and pour points get a hold 10ºC and 3ºC respectively which may present a problem have a handle on use in very cold temperatures.
