Effect of alkalis (NaOH, KOH and K2CO3) on liquefaction of EPFB (empty palm fruit bunch) biomass liquefaction was investigated under subcritical water conditions in a batch reactor operating at 270°C and 20bars for a period of 20min. Catalytic performance and suitable biomass to water ratio...

Nigeria is among the World’s 10 most important exporters of petroleum, but has several difficulties in its domestic energy situation. Power outages are frequent in the cities and 49% of the population has no access to electricity at all. The use of fossil fuels and firewood causes many...

A novel ionic liquid (IL) blend system, consisted of a solvent IL for biomass dissolution and an acidic IL for acid-catalyzed hydrolysis of the released polysaccharides into simple sugars, was developed for the pretreatment of macroalgae Gelidium amansii. Acidic ILs with varying Hammett...

The conversion of cellulose hydrolysis was investigated in batch reactors from brown macro-algae under extremely low acid (ELA) pretreatment conditions. The brown macro-algae of Laminaria japonica were conducted for increasing glucan content as an aqua-biomass feedstock. The investigated ELA...

The catalytic copyrolysis of waste particle board (WPB) and polypropylene (PP) was investigated for the first time over HY (5.1), HY (30), H-Beta and Ga/H-Beta catalysts. The catalysts were characterized by BET and NH3-TPD analyses. The catalytic pyrolysis of the WPB increased the production of...

Bio-oil derived via slow pyrolysis process of two indigenous Australian tree species, red gum (Eucalyptus camaldulensis) from the basin of Murray, Victoria, and blue gum (Eucalyptus globulus) wood from the region of Mount Gambier, South Australia was blended with ethanol and burned in a circular...

Threat of global warming and imminent exhaustion of fossil fuels call for development of alternative carbon-neutral energy sources. Among others, bio-oil, which can be produced from various biomass, can be used not only as an alternative fuel but also as a feedstock for production of high-value...

Considerable attention has been given to development of renewable energy due to imminent exhaustion of fossil fuels and environmental concerns over global warming. Bio-oil is recognized to be a promising alternative energy source because many different kinds of biomass, including agricultural...

Pyrolysis experiments have been conducted on a sample of rapeseed to determine particularly the effects of pyrolysis temperature, heating rate, particle size and sweep gas flow rate on the pyrolysis product yields and their chemical compositions. The maximum oil yield of 73% was obtained at the...

Reactivity and product distributions in the conversion of five different compounds representing typical species in bio-oils were studied over an equilibrium FCC catalyst at 500 °C during 60 s in a fixed bed reactor. Acetic acid, methyl acetate, furfural, 3-methyl-2-pentanone and...
