Research Projects - the list

A laboratory scale pyrolysis/gasification unit has been designed and built. This facility will shortly be operational at Carbolea and will be used to process a variety of residues, wastes and dedictaed agricultural crops..

The webpage detailing our work, on the design and construction of a pilot-scale 10kg/hr pyrolyser/gasifier here at the University of Limerick has been updated. Witold Kwpainski and JJ Leahy are the persons with most involvement in this project. More details can be found on the appropriate webpage.

 

 

A major project is underway involving the production of biochar and the analysis of its properties and how these influence its utility as a plant growth promoter, pollution remediant, and means for sequestering atmospheric carbon.

Bio-Oil is being produced via fast and slow pyrolysis from various feedstocks, including municipal and agricultural wastes and energy crops such as Miscanthus. These bio-oils are then characterised via a variety of analytical methods. Various routes for upgrading the quality of these bio-oils are also being investigated.

Paper Published on Metal Ions Adsorption on Biochar

A paper has been published containing work conducted at the University of Limerick and at the Maria Cure-Sklodowska University in Lublin.

Abstract: Kinetic and adsorption studies on the removal of metal ions such as Cu(II), Zn(II), Cd(II) and Pb(II) ions in the biochar (BC) samples have been carried out. The effects of several experimental parameters have been investigated using the batch adsorption technique at room temperature. The effectiveness of Cu(II), Zn(II), Cd(II) and Pb(II) ions removal increases with the increasing initial concentration of biochar and metal ion, pH as well as phase contact time. The maximum adsorption was found in the pH range 5.0-6.0. The kinetics of adsorption was found to be pseudo second order with intraparticle diffusion as one of the rate determining steps. Adsorption studies were also performed at different temperatures and modelled with the Langmuir and Freundlich adsorption isotherms.

Prof Erik Heeres and Prof Hans de Vries visited Carbolea group

Two distinctive researchers from University of Groningen (Holland) visited our labs and pilot plant installation for acid hydrolysis of biomass (DIBANET). Both parties will be looking for possible research collaborations. The guests gave a lectures on "Recent developments in pyrolysis oil upgrading" - Erik Heeres and "HMF synthesis and derivatives" and "Cashew nut valorisation" - Hans de Vries.

Paper Published on Pyrolysis of Residues from the DIBANET Process

A paper has been published containing work by Carbolea members on the pyrolysis of the acid hydrolysis residues that are produced as a byproduct of the DIBANET process. The paper is entitled "Characterisation of the products from pyrolysis of residues after acid hydrolysis of Miscanthus" and can be downloaded from ScienceDirect.

Abstract: Platform chemicals such as furfural and hydroxymethylfurfural are major products formed during the acid hydrolysis of lignocellulosic biomass in second generation biorefining processes. Solid hydrolysis residues (HR) can amount to 50 wt.% of the starting biomass materials. Pyrolysis of the HRs gives rise to biochar, bio-liquids, and gases. Time and temperature were variables during the pyrolysis of HRs in a fixed bed tubular reactor, and both parameters have major influences on the amounts and properties of the products. Biochar, with potential for carbon sequestration and soil conditioning, composed about half of the HR pyrolysis product. The amounts (11–20 wt.%) and compositions (up to 77% of phenols in organic fraction) of the bio-liquids formed suggest that these have little value as fuels, but could be sources of phenols, and the gas can have application as a fuel.

Carbolea's Biochar Research Accepted for Publication

A paper by members of Carbolea entitled “Biochar from Biomass and Waste” has been published in the new journal Waste and Biomass Valorization. This paper examines the roles that soil amendments with biochar can have on soil fertility, carbon sequestration, on the emissions of greenhouse gases from soil, on fertilizer requirements, and on waste management. Results from Carbolea research are presented, showing that biochars produced under different conditions can have varying effects in plant growth. This further strengthens the need for a biochar classification system. The paper can be downloaded http://dx.doi.org/10.1007/s12649-010-9024-8.

On June 2012 the manuscript is the third most often downloaded paper from the Journal website

Research Areas Update: Pyrolysis and Gasification

The webpage explaining the background to pyrolysis and gasification, two key areas of research at Carbolea, has been expanded today. Figures have been added to illustrate these thermochemical processes and a diagram of the bench-scale slow pyrolysis unit has been included. Witold Kwpainski and JJ Leahy are the persons with most involvement in this area. More details can be found on the appropriate webpage.

Project Update:Biochar Production, Analysis and Plant Growth Trials

The webpage detailing our work on the production, analysis and evaluation of biochar has been updated. In particular there are pictures and data on the observations as to how various biochars influence the germination of Maize plants. It has been noticed that there is a siginificant positive effect in the first month of plant growth, when compared with controls, for biochar amended soils. It is hypothesised that this is due to hormonal effects from chemicals (probably from the bio-oil vapours) sorbed on to the biochars. Katerina Kryachko and Witold Kwpainski are the persons with most involvement in this project. More details can be found on the appropriate webpage.
