Thermal conversion process was applies with low density
polyethylene (LDPE) waste plastic without using any kind of cracking catalyst, and two types of temperature was use for diesel grade fuel collection. Experimental purposed LDPE waste plastic was use 100% by weight and initial feed LDPE sample was 800 gm. In this experiment was perform laboratory small scale under Labconco fume hood without vacuum in presence of oxygen and fully closed system. LDPE waste plastic to diesel grade fuel fractional distillation collection temperature was 260-290 ºC and
LDPE waste plastic to direct liquefaction process temperature was 120-430 ºC. Produced fuel was analysis by Perkin Elmer GC/MS, FT-IR and DSC. Fuel density is 0.80 g/ml. By using GC/MS analysis result showed hydrocarbon compounds range is C3 to C28, FT-IR analysis result indicate that produce fuel has functional group such as H Bonded NH, C-CH3, CH3, - CH=CH2, -CH=CH-(cis), C=CH2 etc. DSC analysis result indicates that fuel enthalpy delta H value 18116.1385 J/g. Produce fuel could be use as combustion engines or feed stock for refinery process
