Hydrocarbons from Bio-oils: Performance of the Matrix in FCC Catalysts in the Immediate Catalytic Upgrading of Different Raw Bio-oils
Matrices of FCC catalysts with different content of alumina and the compound catalysts prepared with them including Y zeolite were used to upgrade bio-oils from pine wood sawdust and soybean shell. The biomasses were ...
Pyrolysis of sunflower seed hulls for obtaining bio-oils
Bio-oils from pyrolysis of as received sunflower seed hulls (SSH), hulls previously washed with acid (SSHA) and hulls submitted to a mushroom enzymatic attack (BSSH) were analyzed. The concentration of lignin, hemicellulose ...
Conversion of pine sawdust bio-oil (raw and thermally processed) over equilibrium FCC catalysts
A raw bio-oil from pine sawdust, the liquid product from its thermal conditioning and a synthetic bio-oil composed by eight model compounds representing the main chemical groups in bio-oils, were converted thermally and ...
Fuels from bio-oils: Bio-oil production from different residual sources, characterization and thermal conditioning
Bio-oils from different residual biomass raw materials (pine wood, mesquite wood and wheat shell) were produced by means of conventional pyrolysis at a temperature of 550°C during 60 min. Bio-oils were separated from gases, ...
Catalytic cracking of bio-oils improved by the formation of mesopores by means of Y zeolite desilication
Y zeolite was desilicated by means of alkaline treatments (NaOH 0.05, 0.10 and 0.20 M) during 15 min to produce varying mesoporosity over it. Catalysts were made with a SiO2 matrix and a binder. Pine sawdust bio-oil was ...
Effect of pyrolysis temperature and thermal conditioning on the coke-forming potential of bio-oils
(American Chemical Society, 2011-05)
Bio-oil from the pyrolysis of pine sawdust was subjected to a thermal conditioning process aimed at inducing changes in its composition and physicochemical properties. The objective was to facilitate the coprocessing of ...
