Bio-diesel can be produced from the seeds of Roselle through a molecular reaction called transesterification. The triglyceride molecule and alcohol is reacted with either potassium hydroxide or sodium hydroxide making the reaction faster at 60oC. The reaction is important to make it useful in small diesel engines.
Biodiesel used in an engine must have similar properties to conventional diesel because we need to: maintain thermal combustion, fuel efficiency and consider the effects on biodiesel emissions. Biodiesel from the seeds of roselle. needs certain properties to be compatible with conventional diesel. For example, the manufacturing equipment, temperature control, process time in the different places that make it and the chemical structure.
In this research we will study the basic bio-diesel ester and development for making bio-diesel more like conventional diesel.
