Research on gasification process of loose biomass material with oxygen-enriched air in fluidised bed gasifier
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 materials can be gasified continuously at a temperature between 600 and 750°C. The heating ...

Dynamic analysis of biomass resources with a global land use and energy model
The purpose of the present study is to evaluate global bioenergy potential in consideration of land use competition using a global land use and energy model (GLUE) formulated with a system dynamics (SD) technique and a biomass balance table (BBT) that can show overall biomass flow and bioenergy potential quantitatively. Through a set of simulations, the following results were obtained: (1) The ...

Economic assessment of regional bioenergy systems in Australia: a flow analysis application
This paper describes a modelling tool that integrates Material Flow Analysis, energy production and Greenhouse Gas (GHG) emissions accounting for biomass flows at a regional scale. This tool allows comprehensive analysis of alternative systems for management of biomass waste and bioenergy production in regional areas. Different possible options for processing a range of biomass waste streams can ...

Modification of dolomite for hydrogen production via catalytic gasification of residue derived from biomass hydrolysis
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 been presented using magnesium nitrate as the modifier, which was introduced into the dolomite via a ...

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 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 ...

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 ...

Economic evaluation and environmental benefits of biofuel: an Indian perspective
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 for 10% blending to gasoline. Indian Planning Commission sees tremendous potential in Jatropha curcus ...

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 ...

Assessment of hemicellulose extraction technology for bioethanol production in the emerging bioeconomy
Rising energy costs, climate change and fossil fuel consumption are driving global efforts to transition toward a sustainable 'green' bioeconomy. This pursuit of bioeconomy requires billion tons of feedstocks, development of biomass-based technologies and biorefineries under the overarching principle of sustainability. First generation ethanol has helped to effectively manage the increasing ...

Overview of biomass and bioenergy sources in northern B.C.
Ibrahim Karidio identified four groups of biomass sources: cellulosic materials from wood residues, agricultural crops, animal wastes, and municipal and industrial solid wastes. “B.C. has a huge land mass,” Karidio said. Of the total provincial annual allowable cut, 47% comes from the Northern Interior. B.C. generates 31% of Canadian wood residues and 66% of Canadian surplus wood residues. ...

Uniforet Mill, Quebec, Canada
Biomass Drying For Bioenergy A DRY-REX low temperature biomass drying system was installed at a Uniforet pulp and paper mill in Quebec to dry sludge produced during the paper making process into a high efficiency biofuel. Prior to the DRY-REX project, the mill was spending millions of dollars to treat and landfill the sludge as waste. The DRY-REX system processed 200 wet tons of sludge a day ...

Hardwearing Biomass Fuel Production Machines - Case study
What is Biomass Fuel Briquette? Biomass briquetting press produces Biomass fuel briquette from the bio waste obtained from different sources. The main sources to get this waste material are forest sites, construction sites, and agricultural industries. These fuel briquettes can be used as an alternative for non-renewable fuel coal, petroleum, and natural gas. The main advantage of biomass fuel ...

Development of algae–based technology to mitigate energy crisis in coal mining areas: a critical review
Algal biofuels around the world represent a sustainable pathway to meet increasing demand for fuel and clean energy with reduced environmental impact. More than half of that mass consists of lipids or triacylglycerides which are also found in vegetable oils and are used to produce such advanced biofuels as biodiesel, green diesel, green gasoline and green jet fuel. Algal remediation technology ...

International context and lessons for B.C.
Paul McFarlane presented a paper co-authored by W.E. Mabee and J.N. Saddler. The International Energy Agency (IEA) was founded in 1974 in response to energy concerns. IEA is a forum for energy cooperation among 26 member countries within the Organization for Economic Cooperation and Development (OECD). It interacts with non-OECD countries to enhance supply security, give advice on energy policy ...

Non-Profits Release Report On Improvements To The European Commission’s Bioenergy Policy
On September 5, 2016, a group of non-profits, including Oxfam International, Fern, and Greenpeace, published a report outlining policy measures that should be taken by the European Commission (EC) to ensure that bioenergy is as low-carbon and resource efficient as possible. The report, "A New EU Sustainable Bioenergy Policy Report," was published after EC stated a willingness to listen to new ...

EU bioenergy potential from a resource efficiency perspective
The bioenergy challenge The European Union has set itself the ambitious target to increase the share of renewable sources in final energy consumption to 20 % by 2020 (EC, 2009). This is motivated by the widespread recognition that using fossil fuels to generate energy causes significant harm to the environment and human well.being. Renewable energy technologies offer a way to increase resource ...
