Liquid fuels from woody biomass
Although challenges like global climate change and oil depletion will increasingly drive fuel selection, increasing bioenergy use is only one of many possible responses to these problems. Present biomass liquid fuels are almost all derived from food crops, but their potential for further expansion is limited. Any major expansion of biomass liquid fuels will require use of the more abundant ...

A comparison of fast and slow pyrolysis liquids from mallee
An exploratory comparative study of the fast and slow pyrolysis of eucalyptus mallee has been carried out to explore the differences in liquid yields and characteristics. The study focused on the liquid products, which were fully characterised and good mass balance closures were achieved. The influence of temperature and heating rates on the slow pyrolysis of eucalyptus mallee was investigated, ...

The production of biofuels and renewable chemicals by fast pyrolysis of biomass
Bio-energy can provide more renewable energy requirements than any other technology. This paper focuses on fast pyrolysis as the only thermal process that directly delivers a high yield of liquid. This can be used on site or transported to centralised facilities for utilisation. This offers the potential for optimisation, greater economies of scale and exploitation of bio-refineries. The overall ...

The feasibility of producing alcohol fuels from biomass in Australia
Apart from cost, the net production of energy is the most important factor in evaluating the feasibility of producing renewable fuels from woody biomass. Unlike sugar, the effort required to make woody materials fermentable is considerable, and has been a major barrier to the use of such materials to produce renewable fuels. The Energy Profit Ratio (EPR) of fossil fuels is declining rapidly as ...

Life cycle assessment of fuel production for biomass from dry land afforestation
Biomass has been focused as a fuel resource because of its huge abundance and carbon–neutral characteristics. Thus, we attempted to use tree biomass as the resource to automotive fuel. From the global warming point of view, the biomass energy production from large–scale plantation is required, however, the land use should not be changed from crop field or forest land. In the present paper, the ...

Global bioenergy: problems and prospects
This paper explores the future global potential for bioenergy. We use energy analysis, and more generally climate change effects, as our criteria for evaluation. Since widespread use of new bioenergy is probably decades away, our evaluation attempts to take into account likely future conditions. Previous research displays large variations in estimates of both energy ratio and technical potential. ...

Bio-char refineries: an accessible approach for the development of biomass-based industry
Being a by-product of the well-established charcoal industry, slow pyrolysis bio-oil can be an excellent, cost-effective and renewable liquid fuel. However, even in Brazil, a country with a very clean energy profile and large-scale charcoal production, bio-oil is not properly utilised yet. A simple upgrade of traditional methods of charcoal production can significantly increase liquid fuel ...

Biofuel - Energy Supplier of the Future?
Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation to generate a social- und environmental dilemma. ...
