Pyrolysis | Student Energy

There are two types of Pyrolysis systems. Fast Pyrolysis optimizes bio-oil production by increasing the rate of pyrolysis temperature to 1000°C/second. This process yields approximately 60-70% bio-oil, 15-25% bio-char, and 10-15% syngas. In contrast, Slow Pyrolysis uses slower heating rates and bio-char is the major end product.

Pyrolysis - CPEO
