Removal of char particles from fast pyrolysis bio-oil by microfiltration

Review of recent developments to improve storage and transportation stability of bio-oil

“…Microfiltration, as one of the membranebased particle removal techniques, has been widely used for removal of fine particles (0.02-10 mm) in petroleum [84,85] and water industries [86]. The membrane acts as a barrier that separates two bulk phases and controls the transportation of chemical components through both sides, which is driven by a driving force, such as electric field, pressure, temperature or concentration difference across the membrane [84].…”

A review of recent laboratory research and commercial developments in fast pyrolysis and upgrading

“…Javaid et al [157] and Ford et al [158] applied liquid-phase microfiltration processes to remove char particles from bio-oil to sub-micron levels. Results demonstrate the removal of the major quantity of char particles with a significant reduction in overall ash-content of the bio-oil.…”

Mechanical performance of asphalt mixtures modified by bio-oils derived from waste wood resources

“…The lower tensile strength may be due to the generation of biochars during the mixing and compaction. Previous researches indicate that there are minus biochars in the bio-oils [44,45]. It is also found that the char particles in the bio-oil serves as a catalyst and stimulates the agglomeration of tar particles and polymerization [45,46].…”
