Table 8 Summary of process conditions and effects

From: Microwave pyrolysis of lignocellulosic biomass––a contribution to power Africa

Parameter Condition Optimal condition for fast pyrolysis
Reaction temperature 500–520 °C Constant.
Vapor residence time <2 s Shorter is better.
Secondary cracking Avoid Bad for product quality and yield.
Heat transfer rate 200 °C/s High as possible to increase liquid yield.
Particle size Typically, <2 mm Large particles limit heat transfer, feeding, and fluidization.
