Thermal Cracking of Glycerine to Liquid Fuels on the Tubular Reactor
The Develop alternative fuels replacement the fossil energy are become interested, the biofuels from used vegetable oil is the one choice at applies in new alternative fuels
but the trans-esterification from waste vegetable oil will give small amount of glycerine which have tall impurity and can not apply the advantage is a substance has started for cosmetic production
However, in recent year the study of thermal cracking has becomes to converted long chain hydrocarbon to light hydrocarbon and use the catalyst help in re-arrangement of chain of hydrocarbon become the small-sized hydrocarbon at have the property are similar to with gasoline
This research has the aims for studies the thermal cracking of glycerine to liquid fuels, by study in the continuos tubular reactor diameter of 0.925 centimetre , length of 12 metre under the condition of temperature range of 400 - 600 C, feeding rate of a substance starts 3 - 11 gram per minute The appropriate condition which gave the highest conversion to liquid at about 90.8 %yield at 500 degree Celsius, feeding rate of a substance starts 6.7 gram per minute.
The liquid products goes to analyse by distillate gas chromatograph follows ASTM-D2887 and product distribution were obtained. At temperature of 500 C, feeding rate of 6.7 gram per minute gave the hightest gasoline fraction of 42.85% whereas kerosne 11.82%, gas oil 26.37%, and long residue of 18.96% were obtained
