Evaluation of fast pyrolysis feedstock conversion with a .

We have developed a pyrolysis reactor based on a unique auger-paddle configuration with heat transfer material (HTM) and proved to achieve high heating rates and fast pyrolysis. We tested ten different biomass types and obtained bio-oil yields ranging from approximately 40% for thermally treated wood, to approximately 57% for crop residues .

What is Pyrolysis: Pyro = heat. Lysis = break down.

What is Pyrolysis? Pyro = heat. Lysis = break down. Plastic Pyrolysis is a chemical reaction. This reaction involves the molecular breakdown of larger molecules into smaller molecules in the presence of heat. Pyrolysis is also known as thermal cracking, cracking, thermolysis, depolymerization, etc.

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 - Wikipedia

Pyrolysis - Wikipedia

Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves a change of chemical composition.The word is coined from the Greek-derived elements pyro "fire" and lysis "separating".. Pyrolysis is most commonly used in the treatment of organic materials. It is one of the processes involved in charring wood. In general, pyrolysis of organic .
