Com a alternativa a la producció química a partir fonts petroquímiques, la conversió de biomassa en productes químics valuosos és un camp actualment en desenvolupament. En aquest camp, una àmplia gamma d'enfocaments és fa servir. En aquesta tesi es presenten tres diferents noves estratègies per a la conversió de biomassa: i) producció de sucres fermentables (glucosa) a partir de: cel•lulosa, polpa produïda amb líquid iònic commutable i biomassa. Els sucres obtinguts es sotmeten a una fermentació microbiana; ii) desenvolupar una nova estratègia integrada per a produir un producte químic de valo

Resumen
The diploma thesis deals with a temperature field in a solid fuel during the combustion process. At the beginning of this thesis, research of available literature was conducted to obtain information about the composition of wood, properties affecting the combustion process, and the basics of heat transfer. Afterward, the temperature profiles of the samples were recorded during the measurement in the observation furnace. The temperature profiles of samples of six different sizes which were made of spruce and beech wood were subsequently evaluated and compared. Based on experimentally obtained d

Resumen
A series of detailed studies have been performed to further understand the characteristics of biomass for solid fuel combustion purposes. The characterisation work was carried out in three separate (but interrelated) parts studying each of the different forms/stages of biomass during combustion i.e. original raw biomass, biomass char and biomass ash, respectively. These findings were examined and correlated to see if predictions about combustion behaviour could be made. The effects of blending biomass and coal on milling performance and ash behaviour were also investigated to show the relevanc

Resumen
As the world population and wealth increases it is necessary to look for sustainable alternatives to guarantee modern living standards. With depleting resources and the threat of global warming, biomass is emerging as a promising alternative to lay the basis for a bio-based sustainable economy. New biomass upgrading trends lead to the concept of biorefinery, where a large array of chemicals, fuels and energy can be produced, maximizing the value of biomass. The aim of the present work is to find industrial biorefinery processes developed to produce chemicals and fuels but that at the same time

Resumen
The use of pulverised biomass for electrical power generation is of growing importance in the UK as a route to low carbon electricity. It can be used in existing power stations co-fired with coal or 100% biomass firing. However, this use of biomass has led to several major biomass storage or burner feed explosions in recent years. There is minimal information in the open literature on the explosion risks of pulverised biomass, as the fibrous nature of pulverised biomass results in it blocking the injection system of the standard ISO 1 m3 and 20 L spheres.

An small-scale CHP system has been proposed coupling a single-staged gasification unit with a suitably matched energy recovery device, utilising biomass pellets. Biomass pelletisation is an established industry in Northern Europe however there is no standardisation governing the quality of the pellets produced. The first objective investigated the pressure pelletisation of switchgrass for five types of material preparation. The effects of pelletisation pressure and temperature on the quality of pellets were evaluated in terms of density, strength and durability.

Agricultural and forest residues as well as urban waste derived from forest products contain significant amounts of cellulose which could be converted into ethanol, a liquid fuel.

A detailed study of the gaseous hydrogen chloride hydrolysis was made to examine the possibility of producing ethanol from biomass with a simple process.

The term "biomass" can describe many different fuel types from such sources as trees; construction, wood, and agricultural wastes; fuel crops; sewage sludge; and manure. Agricultural wastes include materials such as cornhusks, rice hulls, peanut shells, grass clippings, and leaves. Trees and fuel crops (i.e., crops specifically grown for electricity production) can be replaced on a short time scale. Agricultural wastes, sewage sludge, and manure are organic wastes that will continue to be produced by society. For these reasons, biomass is considered a renewable resource. When you are citing th

The constructed reactor utilised a rotating blade approach to achieve particle ablation in a 258mm internal diameter reactor. By fulfilling the key requirements of high relative motion and high contact pressure, pine wood particles of maximum size 6.35

Resumen
The objectives of this research were to investigate the parameters affecting the gasification process within downdraft gasifiers using biomass feedstocks. In addition to investigations with an open-core gasifier, a novel open-topped throated gasifier was designed and used. A sampling system was designed and installed to determine the water, tar and particular content of the raw product gas. This permitted evaluation of the effects of process parameters and reactor design on tar and particular production, although a large variation was found for the particulate measurements due to the capture o

Resumen
Strategies to combat climate change focus on every industry and has led to government policies to reduce electricity generation through coal combustion. Switching to biomass provides an opportunity to use infrastructure constructed for coal combustion with carbon neutral fuels; however, the process of grinding biomass pellets as fuel in pulverised fuel combustion is not well known. 1% of energy generated at a power plant is utilised to achieve the required size for the fuel. Improvements in the understanding of biomass pellet milling could lead to optimisation of operating conditions and minim

Resumen
This work makes an attempt to explain the origin, features and potential applications of the elevation bias of the synthetic aperture radar interferometry (InSAR) datasets over areas covered by vegetation. The rapid development of radar-based remote sensing methods, such as synthetic aperture radar (SAR) and InSAR, has provided an alternative to the photogrammetry and LiDAR for determining the third dimension of topographic surfaces. The InSAR method has proved to be so effective and productive that it allowed, within eleven days of the space shuttle mission, for acquisition of data to develo

Resumen
Fast pyrolysis, the rapid thermal decomposition of organic material in the absence of oxygen, is a process that can be used to convert biomass into liquid fuels and chemicals. When performed at the micro-scale, pyrolysis is useful for characterizing biomass structure, as well as determining the pyrolysis products that can be generated from specific biomass feedstocks. Indeed, microscale pyrolysis coupled with on-line analysis of the pyrolysis vapors by GC/MS, so-called pyrolysis-GC/MS (Py-GC/MS), is a technique that can be used to characterize the structure and composition of the various compo

Resumen
Waste biomass as a resource represents an interesting opportunity that imbues the principles of green chemistry within the context of sustainability. Herein, potential routes for valorisation of currently low-value and/or underutilised biorenewable waste streams, namely: spruce wood chips; waste office paper; paper deinking residue (DIR), and; waste starch, using green chemical technologies are reported. Microwave-assisted low-temperature (<200 oC) pyrolysis was conducted on spruce wood chips, waste office paper and paper deinking residue (DIR) to afford three product lines: bio-oil (organic a

O objetivo deste estudo foi desenvolver e validar modelos preditores para a fitomassa epigéa da mata atlântica, formação vegetal que cobre a Serra do Mar no estado de São Paulo. Em duas parcelas de 100m2, 82 árvores foram cortadas, ao nível do solo, e anotadas suas medidas de altura e diâmetro. As folhas foram separadas dos ramos para determinação do peso fresco da porção foliar e lenhosa. Amostras de cada fração foram secas em estufa a 80o C, até peso constante, para determinação do peso seco. As árvores foram distribuídas em duas amostras aleatórias, sendo uma utilizada para o desenvolviment
