Full textThe aim of the proposed research was to provide a better understanding of the mechanisms of biomass torrefaction and to propose practical methods to improve the efficiency of this process. As for the mechanism, torrefaction of two woody biomass samples from Quebec forests (aspen and birch) and their main constituents, i.e., lignin, cellulose and hemicellulose is studied in details using different experimental techniques and a kinetic model is developed for their torrefaction. Our studies on the mechanism and kinetics of biomass torrefaction also revealed the slow rate of biomass torrefaction which motivated us to propose and develop a new ionic-liquid assisted torrefaction process with the aim of increasing the rate of biomass torrefaction. Although torrefaction improves the physicochemical properties of biomass fuel, release of oxygenated hydrocarbons (in the form of volatiles) from biomass reduces its overall energy. To recover volatiles energy, a new combination of biomass torrefaction and chemical looping volatiles combustion was studied. In this regard, the already comminuted, abundant and cheap iron and magnesium bearing silicate minerals found widely in the form of mining residues in the province of Quebec were tested as solid oxygen carrier and up to 96% of volatiles conversion at 700°C was achieved in CLC reactor. As a supplementary work, we were also interested to explore the potential of mining residues containing sizeable quantities of iron for catalytic cracking of tar released during the gasification of biomass. For this purpose, iron-bearing mining residues and minerals obtained from the mining activities in Quebec were evaluated comparatively to olivine (known as an active mineral for tar cracking) for benzene cracking in simulated syngas. It was found that chrysotile showed up to four-fold increase in benzene and methane conversion than olivine.

Full textA method to estimate aboveground dry biomass of Quebec’s forest ecosystems was developed using data from a spaceborn lidar. The study area covers the portion of the province south of the treeline, an area of 1.3 M Km2. Biomass was first estimated for ground inventory plots using allometric equations. A small footprint laser profiler then flew over these inventory plots to develop a generic airborne lidar-based biomass equation (R2 = 0.65, n=207). As well, the Landsat ETM+ land cover map and the vegetation zone maps were used to develop stratified equations (R2 ranging between 0.51 and 0.79). The same airborne lidar system flew along four portions of orbits of the ICESat Geoscience Laser Altimeter System (GLAS). An equation was developed to predict airborne profiling lidar estimates of aboveground dry biomass from GLAS data and from the SRTM digital elevation model (R2 = 0.59, n=1325). These results allowed us to use the 104,044 GLAS pulses available over the study area to estimate the total aboveground dry biomass for the main vegetation areas of Quebec as well as for the entire study area. Biomass for the entire study area averaged 39.0 2.2 (standard error) Mg ha-1 and totalled 4.9 0.3 Pg with 36% of this biomass located in non-commercial forests and 51% located in the boreal forest (both commercial and non-commercial).

Full textTo ensure sustainable development in a temperate mixedwood boreal forest in central Quebec (Canada), forest managers would like to measure the historical impact of harvesting on forest cover evolution at the landscape level. The main objective of this study was to document, at the landscape level, the historical effects of harvesting on forest cover evolution and wood volume. The study was mainly based on archival records, particularly AbitibiBowater inc 's archives. The objective of the first chapter of this study was to characterize the pre-industrial forest. The main natural disturbances were big fires in 1870 and 1923 and three spruce budworm epidemics in the 20th century. Whatever the scale considered in this study, the pre-industrial forest cover was mainly composed of mature or old-growth (> 100 years) and dominated by mixedwood forest stands with intolerant hardwoods. The main forest species were white birch, black spruce and jack pine, three species associated to forest succession after fire in the boreal forest. Chapter 2 had as objectives to make an historical reconstruction of forest cover evolution in 14 landscapes and to qualify the possible effects of harvesting. For the latter, we used three analytical methods in a triangulation approach. The main alteration of forest harveting on forest cover was qualified as additive to the natural dynamic, particularly considering the increase of intolerant hardwoods. The objective of chapter 3 was to make an historical reconstruction of wood harvesting in a past forest concession (Vermillon). We monitored indicators of forest sustainability in order to discuss the impacts of forest concession revocation in 1986. In the context of our study we noted an increase of wood harvesting after the revocation. Although we were unable to conclude that the new policy was a threat to wood production sustainability, on a sustainable yield basis, our security margin has surely diminished since the introduction of the policy of 1986. “To keep in mind the actions we have done and their results” should be a leitmotiv in our forest management. At least, we should record the data collected during regular operations.

Full textEnglish Title : Soil and native woody crop properties on an abandoned agricultural field harvested with a Biobaler. Natural woody crops overtake abandoned agricultural land. To bring back these areas into useful production, traditional methods include prescribed burning or on-site mulching. A recent technology, the Biobaler cuts and forms round bales of woody crops which can be moved for useful application. An agricultural field in Saint-Augustin-de-Desmaures (Quebec, Canada), abandoned for 20 years, was monitored for crop identification and soil properties. Allometric models were developed for 11 native woody crops (average R² of 0.93). Soil pH averaged 5.0, total N, 0.32% and organic carbon, 4.0%. Sixty two bales were harvested, averaging 413 kg at 44% moisture. The harvested biomass, between 3.3 and 9.6 t of dry matter per hectare, represented 18 to 43% of above-ground biomass. Data will be useful in assessing Biobaler operation on fallow land.

Full textWe have used a Q-methodology survey – a subjectivity studying technique – to explore different perceptions of forest certification in Quebec. Three different viewpoints were discovered. We have also done an analysis of institutional changes within Quebec's forest sector. As a result, we expect Quebec's forest regime to undergo an important effort of decentralization in which forest certification will play an important role. First, we have individuals who primarily view certification as a tool of management and who may place greater importance on forest industries' certification leadership. People in this category may want the traditional role of private firms as developers and managers of the crown's forests to be secured. On the other hand, there are people who view certification as a tool for public relations and who may be opposed to preserving the traditional role of private firms. For this group of people, proof of improvement of certified forest practices would be a requirement. Finally, people who view certification as a tool of governance may approve of reform and thus, try to catalyze it. Such individuals will demand an enhancement of public involvement processes in the forest sector. This group of people will want forest management responsibilities and power to be more equitable.
