In the final stage, the pyrolysis products are cooled and separated into their desired forms. The bio-oil can be used as a fuel, biochar as a soil amendment, and syngas as a fuel or for electricity generation. The pyrolysis process may vary depending on the feedstock used and the desired end product.

What Is The Difference Between CVD And PECVD?

The difference between PECVD and traditional CVD technology is that the plasma contains a large number of high-energy electrons, which can provide the activation energy required in the chemical vapor deposition process, thus changing the energy supply mode of the reaction system. Since the electron temperature in the plasma is as high as 10000K, the collision between electrons and gas molecules can promote the chemical bond breaking and recombination of the reaction gas molecules to generate more active chemical groups, while the whole reaction system maintains a lower temperature.

So compared to the CVD process, PECVD can carry out the same chemical vapor deposition process with a lower temperature.
