Abstract

In this work, co-gasification of tyre waste (TW) with rice husk (RH) is conducted to improve RH gasification by investigating the equivalence ratio (ER) and blending ratio (BR). The optimal operating condition is identified as BR41 and ER 0.25 for co-gasifying TW/RH. The concentration of combustible gases is determined to be 21.66 vol % CO, 3.9 vol % CH4, and 13.73 vol % H2, with the lower heating value (LHV) of the producer gas measured as 5.66 MJ/m³. The gasifier generates 2.5 m³ of gas is from per kg of BR41. Co-gasification has reduced the char yield to 4.56 kg/h. The system can generate the producer gas of 338,924.4 m3 annually, of which the combustible gas comprises 47.66 %. The system has a capital expenditure (CAPEX) of USD 70,358.6 and an operational expenditure (OPEX) of USD 52,254.06 per year and it has the estimated cost of syngas production is 0.13 USD/m3. The environmental analysis indicates that the system has the potential to generate 102.49 gm of CO2, resulting in an annual reduction of 36.095 tCO2e and a carbon credit of 86 USD/tCO2. This means co-gasifying RH/TW is viable, making BR41 suitable for thermal and power generation and tyre waste management.
