In-Situ Catalytic Fast Pyrolysis Technology Pathway [PDF]
, 2013 This technology pathway case investigates converting woody biomass using ex-situ catalytic fast pyrolysis followed by upgrading to gasoline-, diesel-, and jet-range hydrocarbon blendstocks. Technical barriers and key research needs that should be pursued for this pathway to be competitive with petroleum-derived blendstocks have been identified.

Products distribution during in-situ and ex-situ catalytic fast pyrolysis of Chinese herb residues
SSRN Electronic Journal, 2022 Abstract Catalytic fast pyrolysis (CFP) for biomass treatment is a research hotspot but there is little information about the difference between the in-situ and ex-situ methods. In present work, the Ni-Fe/CaO-Al2O3 catalysts with different Ni/Fe ratios have been synthesized by coprecipitation method, and the products distribution about the ...

Techno-economic and uncertainty analysis of in situ and ex situ fast pyrolysis for biofuel production [PDF]
Bioresource Technology, 2015 This study evaluates the techno-economic uncertainty in cost estimates for two emerging technologies for biofuel production: in situ and ex situ catalytic pyrolysis. The probability distributions for the minimum fuel-selling price (MFSP) indicate that in situ catalytic pyrolysis has an expected MFSP of $1.11 per liter with a standard deviation of 0.29,
