Rheological behaviour of liquid fuel emulsion by food waste based on char slurry and nonionic surfactant

Nowadays, world have facing with many challenging and famous issues that is pollution. Municipal solid waste especially food waste contributes to the greenhouse gas emission via decomposition and life cycle activities process. Landfill is the main causes to the gas emission to the environment and landfill is the first strategies in handling the solid waste. Alternative ways have been recovered to minimize the greenhouse gas emission to the environment by converting the food waste to liquid fuel that are more environmental friendly. The purpose of this research conducted to determine the optimum temperature of pyrolysis to produced biochar using food waste by calculating and analyzing the highest carbon value of char produced. This research also is done to study the rheological behavior of biochar slurry as liquid fuel using non-ionic surfactant. The food waste that are being used in this research is tofu where the tofu was collected from the restaurant near Seksyen 7, Shah Alam. The tofu was pyrolysed at temperature in range 400-600 oC with time taken 4 and 5 hours respectively. The pyrolysed tofu was grind and analyzed their carbon content, energy density and ash content. The highest carbon content of biochar was selected to analyze the rheological behavior using rheometer. The highest carbon content is obtained at decreased temperature and time taken. From experimental result that has been conducted, the highest carbon content was obtained at temperature 400oC with time taken 4 hours with 62.7965% of carbon in the biochar.
