Experimental cyclic variations of diesel engine burning pyrolysis castor oil blends

Pyrolysis of castor oil with anhydrous sodium hydroxide as a catalyst was performed to produce Catalytic Castor pyrolytic oil (CCPO). The physical and chemical properties of the pyrolytic and gas oils were recorded according to ASTM standards. Gas oil was blended with castor pyrolytic oil at differe...
