Despite its prominent potential, the use of rubber wood (Hevea brasiliensis) for bio-oil production has not been fully investigated. This study reported experimental results of the bio-oil production and upgrading from rubber wood using fast pyrolysis technology. The effects of catalyst nature (vermiculite and dolomite), upgrading temperature and bio-oil/catalyst ratio on the product quality were deeply investigated. The results showed that dolomite was suitable to be used as a catalyst for bio-oil upgrading. At 600 °C and a bio-oil/catalyst ratio of 1:1, the bio-oil yield was maximized, while at 400 °C and a ratio of 1:3, the bio-oil heating value was maximized. Depending on usage purposes, a yield-oriented, heating value-oriented or in-between bio-oil upgrading solution could be considered.

Fast pyrolysis is one method of creating bio-oil from biomass such as native prairie grasses, corn stover, and other organic commercial and industrial byproducts. In this study, fast pyrolysis of camelina (Camelina sativa) meal feedstock was performed in an auger-type reactor. End products of the processing consisted of bio-char and condensed vapor in the form of bio-oil (ranging from liquid to highly viscous tar-like products). The bio-oil produced in the reactor was collected and analyzed to determine the effects of reactor and condenser temperatures on the properties of the bio-oil produced. Five reactor temperatures and two condenser temperatures were investigated in this study. The rheological properties of the bio-oil samples were analyzed, water content was determined with the Karl Fisher method, energy content was measured with a bomb calorimeter, and acidity was determined using a total acid titration test. The aging characteristics of the bio-oil were also investigated at seven days, fourteen days, and twenty-eight days after the oil was created to determine what effect, if any, time had on the its properties. Preliminary results indicated that products of the camelina meal pyrolysis process were more uniform when compared to that of other feedstocks (e.g. carinata meal, corn stover), yielding more consistent bio-oil characteristics.

Fast pyrolysis of corn stalk was performed at temperatures in the range of 450 - 600 °C in a fluidized bed. The chemical composition of bio-oil was analyzed by GC–MS, and its main properties were determined. The results showed that the bio-oil yield increased with increasing pyrolysis temperature from 450 °C to 500 °C and then declined with a further increase in pyrolysis temperature. The highest bio-oil yield of 43.3wt% was obtained at 500 °C with the dolomite as bed material. The char yield always decreased with the rise of temperature. The major chemical compounds of bio-oil included hydroxyacetone, butanone, acetic acid, propionic acid, ethylene glycol, phenol, etc.
