Experimental results of gasification of waste tire with air in a bubbling fluidized bed gasifier

► Lower ER values result in higher CH4 concentration and LHV. ► Four bed materials are tested to verify the change of LHV with ER. ► Bed temperature significantly changes the LHV. ► The LHV-ER relation is different for various ER regions. ► Three correlations are produced to find LHV in the ER range of 0.15-0.60.
