Abstract
- We investigated the potential application of anaerobically digested residues for generating bioenergy in the presence of alkali bifunctional material, sodium zirconate (Na <subscript>2</subscript> ZrO <subscript>3</subscript> , NZ) using a thermogravimetric analyzer connected to a mass spectrometer. Isoconversional kinetic models, compensation effect and master-plots method were used on data obtained under multiple heating rates (10, 15 and 20 °C min <superscript>-1</superscript> ) to calculate the activation energy (E <subscript>α</subscript> ) and pre-exponential value (A) and reaction mechanism. The average E <subscript>α</subscript> for blend samples C-DSW (NZ mixed with digested municipal solid waste (DSW)), and C-DSM (NZ mixed with digested swine manure (DSM)) were 172.24 and 171.63 kJ mol <superscript>-1</superscript> , which were much lower when compared to plain samples, DSW (202.51 kJ mol <superscript>-1</superscript> ) and DSM (215.22 kJ mol <superscript>-1</superscript> ). The total gas yields increased by 19.5 and 17.1% for NZ blended samples C-DSW and C-DSM, respectively. In addition, the hydrogen yields also increased by 79 and 44% for C-DSW and C-DSM, respectively.<br /> (Copyright © 2022 Elsevier Ltd. All rights reserved.)
