A quasi steady state model for flash pyrolysis of biomass in a transported bed reactor

In this work a quasi-steady state Lagrange multiphase model for biomass pyrolysis in a transported bed reactor was developed. Using biomass three components and lumped kinetic model and char-gas ratio in the thermochemical conversion of biomass to tar, gas and char. The transported bed reactor opera...
