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. |
