Effects of different combustible municipal solid waste components without/with additives on co-pyrolysis

ABSTRACT

This article studies co-pyrolysis of combustible municipal solid waste (MSW) without/with additives (CaO, CuCl₂, zeolite powder, and MnO₂). Co-pyrolysis of different MSW components mixing and adding additives in co-pyrolysis could change yield of oil, high heating value (HHV), and products distribution. The yield of oil increases noticeably, but HHV decreases with ratio (sawdust: paper) increasing. Moreover, the yield of phenols increases. After adding fabric, the yield of acids and alcohols increases and that of aldehyde decreases. The yield of oil decreases after adding CaO and MnO₂, and HHV of co-pyrolysis increases after adding CaO, zeolite powder, and MnO₂. Adding MnO₂ has the most impact on the decrease of aldehyde, and adding CuCl₂ has the biggest effect on phenol reducing. The yield of ketone is affected most greatly by adding CaO.
