Fluidised bed gasification technology with oxygen-enriched air suitable for gasifying loose biomass materials was developed. Gasification experiments with different biomass materials such as rice straw, rice hull, wheat straw, sawdust and municipal wastes, were carried out. The tests showed that...

Biomass based fuel technologies are rapidly developing and the barriers in implementing such technologies are being identified to achieve their widespread commercialisation. The two most common biofuels are biodiesel and bioethanol. About 500 million litres of ethanol is required in India itself...

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...

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...

In this paper, three PCM based foot warmers of cylindrical and rectangular in shape were designed, developed and fabricated to store solar energy during sunshine hours. The stored energy was utilised to warm the feet in the late evening to replace electric heaters. By trial experiment, it was...

There is scope internationally to utilise surplus and degraded agricultural land for biomass crops that might also be environmentally beneficial. For example, dryland salinity in southern Australian could be ameliorated using profitable woody biomass crops. A model was developed to predict...

The role of farmers as future energy producers of China is explored within a fast changing rural economy. Data on rural households energy demand, socio-economic and environmental data are used from a household survey with a geographical spread over China. A concept of a more flexible energy...

In this paper, the effects of light intensity on the hydrogen production of Rhodobacter sphaeroides 1.1737 using swine manure wastewater as substrate were investigated. The results show that the increase in light intensity increases both hydrogen production rate and total hydrogen evolved by...

Calcined dolomite is a good catalyst in terms of its activity for gasification of residue derived from biomass hydrolysis for hydrogen production, whereas its fragility can cause trouble during operation. A novel modification method aimed at improving the strength of the calcined dolomite has...
