文摘
- •
Primary paper waste sludge (PWS) was gasified in supercritical water at 450 °C.
- •
Addition of K2CO3 catalysed the water-gas shift reaction to yield 7.5 mol/kgPWS H2.
- •
90% conversion of carbon to the gas phase achieved with Ni–Al2O3/SiO2 catalyst.
- •
83% energy recovery achieved with Ni–Al2O3/SiO2 catalyst.
- •
Gas product with HHV of 13.3 MJ/kgPWS achieved with Ni–Al2O3/SiO2 catalyst.
