Abstract:

Fast pyrolysis is an emerging technique by which a liquid product, biooil is formed. The fast pyrolysis can be done using various reactors such as fluidized bed reactors, transported and circulating fluidized bed reactors, ablative and vacuum reactors, tubular reactors, microwave pyrolytic reactors,auger system and rotating cone reactors. Among them fluidized bed system is a well understood technology and available for the commercialization of fast pyrolysis. In this review, the process parameters in fluidized bed system that enhance the biooil production were reviewed. Utilization of various

Abstract:

In the future, renewable energy technologies will have a significant role in catering to energy security concerns and a safe environment. Among the various renewable energy sources available, biomass has high accessibility and is considered a carbon-neutral source. Pyrolysis technology is a thermo-chemical route for converting biomass to many useful products (biochar, bio-oil, and combustible pyrolysis gases). The composition and relative product yield depend on the pyrolysis technology adopted. The present review paper evaluates various types of biomass pyrolysis. Fast pyrolysis, slow pyrolys

This study highlights the potential use of forestry residues with waste eggshells under a nitrogen environment. The experiments were conducted to increase the yield of bio-oil by changing the parameters such as pyrolysis temperature, particle size, and catalyst ratio. Under noncatalytic pyrolysis, a maximum bio-oil yield of 40.9 wt% was obtained when the feedstock was pyrolysed at 500°C. During catalytic pyrolysis, the yield of bio-oil was increased by up to 16.95% comp

AbstractThe algae biomass is one of the potential biomass resources for extracting lipid to produce fuel. The off grade or residuals of dehydrated algae particles can be used in pyrolysis reactions to produce fuel or useful chemicals. Due to higher ash contents of algae biomass, pyrolysis process needs an appropriate design of pyrolysis reactor. The heating rate of algae biomass is a key factor for increasing of bio-oil production rate. Instead of heat transfer from reactor walls to the biomass, heated inert particles are added to the conventional fluidized bed reactor to increase heat transfe

Addition of a fluidized bed combustor to a high-efficiency combined cycle plant enables direct firing of inexpensive run-of-the-mine coal in an environmentally acceptable manner. To attain high thermal efficiencies, coal pyrolysis is included. The low heating value fuel gas from the pyrolyzer is burned in a topping combustion system that boosts gas turbine inlet temperature to state of the art while the pyrolyzer-produced char is burned in the bed. The candidate topping combustor, the multi-annular swirl burner, based on a design by J. M. Bee´r, is presented and discussed. Design requirements

The Combustion Reduction Integrated Pyrolysis System (CRIPS) is a dual fluidised bed fast pyrolyser that was developed at the University of Pretoria for the conversion of biomass waste to biofuels. The dual fluidised bed design allows in situ catalytic upgrading of bio-oil, by providing the conditions required for the regeneration and decoking of catalysts. The first version of the CRIPS process (CRIPS 1) emphasised the need for an energy balance approach to model the pyrolysis process rather than a mass balance. CRIPS 1 experienced severe energy losses and as a result very poor performance wa

Abstract:

This thesis explores the previously-unreported phenomenon of bed agglomeration during biomass fast pyrolysis in fluidised bed. Experimental work was carried out to characterise bed agglomerates formed. The differences in bed agglomeration behaviour were also identified among the fast pyrolysis of various mallee biomass components (wood, leaf and bark). A new parameter (sand loading) has also been developed for diagnosing bed agglomeration during biomass fast pyrolysis in fluidised bed under a wide range of conditions.

Increasing temperature results in an increase of the gaseous product. There is an optimum temperature on the maximum liquid yield, which is around 650°C. An increase in particle size leads to a decrease of liquid products. Some amount of phenol group was found in the liquid products, which may produce the chemicals with high value.

When a solid fuel, such as coal, biomass or a mixture of these fuels, enters a hot fluidized bed, the volatile carbon and nitrogen compounds are released, while some nitrogen and carbon remains in the solid char. Volatile nitrogen can form reactive species such as NH3, HCN and tar-nitrogen. These can react in the presence of oxygen to NO (and some N2O). Some part of volatile nitrogen is always reduced to N2. During combustion of the char residue, some part of the char-nitrogen forms NO (or N2O) and the rest is converted to N2. Usually the standard fuel analysis is not enough to allow for accur
