Abstract

A newly designed inverted batch reactor equipped with a pressure-driven feeding system was built for investigating the kinetics of syngas during the steam hydrogasification (SHR) of biomass. The system could instantly load the feedstock into the reactor at high temperature and pressure, which simulated the way to transport the feedstock into a hot and pressurized gasifier. Experiments were conducted from 600 °C to 700 °C. The inverted reactor showed very high heating rate by enhancing the carbon conversion and syngas production. The kinetic study showed that the rates of CH₄, CO and CO₂ formation during SHR were increased when the gasification temperature went up. SHR had comparatively lower activation energy for CH₄ production. The activation energies of CH₄, CO and CO₂ during SHR were 42.8, 51.8 and 14 kJ/mol, respectively.
