TLDR
Fast pyrolysis for production of liquids has developed considerably since the first experiments in the late 1970s as mentioned in this paper, leading to significant advances in process development and a wide range of reactor configurations that have been developed to meet the stringent requirements for high yields of useful liquids, for use as a fuel in boilers, engines and turbines and as a source of chemical commodities.Abstract:
Fast pyrolysis for production of liquids has developed considerably since the first experiments in the late 1970s. Many reactors and processes have been investigated and developed to the point where fast pyrolysis is now an accepted feasible and viable route to renewable liquid fuels, chemicals and derived products. It is also now clear that liquid products offer significant advantages in storage and transport over gas and heat. These advantages have caused greater attention to be paid to fast pyrolysis, leading to significant advances in process development. The technology of fast pyrolysis for liquids is noteworthy for the wide range of reactor configurations that have been developed to meet the stringent requirements for high yields of useful liquids, for use as a fuel in boilers, engines and turbines and as a source of chemical commodities. This review summarizes the key features of fast pyrolysis and the resultant liquid product and describes the major reaction systems and processes that have been developed over the last 20 years.read more

Characteristics and origin of char and coke from fast and slow, catalytic and thermal pyrolysis of biomass and relevant model compounds
TL;DR: In this article, a comparison of char and coke from pyrolysis of different biomass types is investigated, and it is shown that char forms as an external layer on the catalyst surface and in its macropores, whereas coke forms inside the zeolite micropores via hydrogen transfer and addition reactions.

Catalytic upgrading of biomass pyrolysis vapours using faujasite zeolite catalysts
TL;DR: In this paper, the influence of faujasite catalysts on the pyrolysis of pinewood was investigated and it was shown that in the same condition, in-situ catalytic upgrading of bio-oil vapour is superior to in-solvent catalytic pyrolynsis of biomass when it comes to quality of biooil.
