The potential of algal biomass as a source of liquid and gaseous biofuels is a highly topical theme, but as yet there is no successful economically viable commercial system producing biofuel. However, the majority of the research has focused on producing fuels from microalgae rather than from...

Liquefaction bio-oil from sewage sludge using different organic solvent (methanol, ethanol or acetone) at temperature of 260–380 °C was characterized in terms of its elemental and chemical composition, and was further upgraded by microemulsion technology. The bio-oil obtained had high carbon...

Pyrolysis is one of the potential routes to harness energy and useful chemicals from biomass. The major objective of biomass pyrolysis is to produce liquid fuel, which is easier to transport, store and can be an alternative to energy source. The yield and composition of pyrolysis oil depend upon...

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...

Lignocellulosic biomass, microalgae and sewage sludge have distinct compositions and structures to each other. To understand the effect of feedstock differences on biomass liquefaction process, the liquefaction characteristics of rice straw (lignocellulosic biomass), Spirulina (microalgae) and...

The effect of reaction temperature, retention time, biomass content, and catalyst loading on bio-oil yield, carbon content, and carbon recovery of corncob hydrothermal conversion was investigated and optimized via response surface methodology (RSM). The four variables ranged from 280 to 340°C...

Major challenges of the modern world: energy security, oil price, resources depletion and climate change, have prompted significant advances in research and development of biomass-derived energy and fuels. Algal biofuels are seen as one of the most promising solutions of global energy crisis and...

Increasing biofuel production on agricultural lands in tropical island nations will likely result in increased deforestation [1], and also inflate food prices, especially in net food importing countries like the Philippines [2–4]. Compounding problems associated with promotion of biofuels in...

Under the Biofuels Obligation Scheme in Ireland, the biofuels penetration rate target for 2013 was set at 6% by volume from a previous 4% from 2010. In 2012 the fuel blend reached 3%, with approximately 70 million L of biodiesel and 56 million L of ethanol blended with diesel and gasoline,...

Global outlook of biofuels turns out to be a full-fledged search focusing the viability and sustainability assets. The present day option for immediate and sustainable alternate fuels lies with algal biofuels. Algae are the most sustainable fuel resource in terms of food security and...
