| Summary: | Increasing consumption of fossil fuels is posing risk to Thailand since non-renewable fossil fuel sources are depleted rapidly. Low carbon energy is becoming more attractive. Used cooking oils from food processing are excessively available and usually disposed of as wastes. These waste oils may be upgraded to biofuels via catalytic cracking, which is regarded as a popular method for producing light hydrocarbons similar to petroleum derived fuels. In this study, catalytic cracking experiments were carried in a fixed bed reactor with mixed catalyst (ZSM-5 and Y-Re-16). Three operating parameters were considered; reaction temperature (300 to 500๐C), catalyst to oil ratio (5 to 20 %w/w), and ZSM-5 to Y-Re-16 catalyst mixture ratio (0 to 100 %w/w). The objective of this study was to evaluate influence of operating parameters on yields of organic liquid product from catalytic cracking of used cooking oil. The optimum condition was at 300๐C, 5%w/w catalyst loading, and ratio of ZSM-5 to Y-Re-16 as 97:3. The result showed the maximum yield of 84.84% consisting of gasoline 12.11%, kerosene 8.95%, and diesel 71.43%.The physical properties of liquid product were found to be in range similar to commercial diesel in Thailand |
