Slow pyrolysis of wood
Webb3.1. Slow Pyrolysis Slow pyrolysis has been used for thousands of years to enhance char production at low temperatures and low heating rates. In this process, the vapour residence time is too high (5 min to 30 min) and components in the vapour phase continue to react with each other which results in the formation of solid char and other liquids ...
