Microwave Pyrolysis (MP) of Sewage Sludge: Profile of Bio-Fuel Production

Abstract:

This paper mainly focused on the characteristics of pyrolysis temperature and the bio-fuel production, and the energy recovery efficiency of sludge by MP was also explored.The results show that the final temperature of sample added carbonaceous residue (CR) is above 700°C and the maximum heating rate is up to 1.783°C/s. While the maximum heating rate of sludge with activated carbon (AC) is 1.084°C/s. The caloric value of the oil production can reach 41.57MJ/kg, and the content of PAHs is less than 4.54%. The volume fractions of H₂ and CO in the gas production are higher than 54%, and the caloric values are higher than 9 540kJ/m³. The oil and gas production can use as the bio-fule.The energy of total bio-fuel obtained sample with CR is 6.99MJ/kg, and the energy recovery ratio is up to 45.63%. The MP is a potential method for the energy recovery of sludge.
