Several works available in the literature have addressed regression models for the prediction of mass yields and elemental composition of the bio-oil/biocrude produced from biomass thermochemical liquefaction (i.e. pyrolysis and HTL), based on its biochemical composition. However, I haven't been able to find any work going further and predicting the relative amount of representative families of compounds (e.g. alcohols, carboxylic acids, phenols, etc.) in the bio-oil/biocrude.
A couple of works (Article Development of an automated method for modelling of bio-crud...
,Article Modeling of thermochemically liquefied biomass products and ...
) have proposed computational algorithms for the chemical characterization of bio-oils/biocrudes by using a reduced number of compunds but, in the end, they rely on experimental data such as biocrude GC-MS/Simulated Distillation.My idea, obviously, is not to get a detailed composition profile, but at least to be able to describe how biomass composition and process operating conditions affect the relative amount of maybe 10 to 15 representative compunds.
I would appreciate any ideas on the topic.
Best regards

Fatima BoukhlifiI believe the question is more interested in predictive methods rather than analytical methods after the fact.
Dear Enrique,
factors for obtaining bio-oil / biocrude:
- the ratio of C, H, O, N - more precisely:
- moisture level H2O in wood / biomass;
- the ratio of cellulose, hemicellulose, lignin;
- blowing with air, or lack of oxygen, atmosphere of inert gases, water vapor;
- atmospheric pressure, high pressure or vacuum;
- limiting process temperatures, constant heating or isotherm, stepwise process;
- time of processing;
- heating rate, deg / min.
It is already known that with slow heating of moist wood at 400-450 C, the yield of liquid pyrolysis products is greater than dry wood at 550-600 C. Accordingly, the composition changes from the factors listed above.
I have research on the composition of hardwood pyrolysis fluid and coniferous pyrolysis fluid.
If you are interested, we can discuss additionally [email protected]
Its quite important to get the BMP test done and after particular days we can also start testing the effluent or the slurry on daily basis to get the actual data too
