Currently, lump charcoal, the cooking fuel of Haiti, is made by carbonizing trees in ditches before selling the charcoal at market. However, Haiti is now 98% deforested and must find a way to prepare their food that does not destroy their land. The idea for this new fuel comes from compressed and extruded carbonized bagasse, which w

Abstract:

At a steel mill, charcoal from biomass is a potential substitute to coal as a reducing agent in the Blast Furnace. The steel industry accounts for 5 % of the global CO2 emissions. Charcoal, being a renewable fuel, has the potential to mitigate the steel industry’s contribution to global warming. If charcoal were to replace the pulverized coal injected into one of Sweden´s two blast furnaces an estimated 1,13 Mton raw biomass per year would be required, this is equivalent to 2,5 % of the total available biomass in Sweden the year 2020 . If this is to be realized, a well optimized pyrolysis proc

Abstract:

Until relatively recently, archaeologists and historians have tended to ignore the burial practice of the late Anglo-Saxon period (<i>c</i>. AD 800-1100) in favour of other aspects of the archaeology of this period, or of the burial practice of earlier periods, assuming that burial in this period is uniform and well-understood. In fact, the late Anglo-Saxon period shows a great deal of diversity in burial practice. One of these diverse forms of burial is so-called “charcoal burial”, in which the body or coffin is laid on or under a layer of wood charcoal. This thesis examines the possible symb

Quantifying charcoal particles preserved in sedimentary environments is an established method for estimating levels of fire activity in the past, both on human and geological timescales. It has been proposed that the morphology of these particles is also a valuable source of information, for example allowing inferences about the nature of the vegetation burned. This thesis aims to broaden the theoretical basis for these methods, and to integrate morphometric study of sedimentary charcoal with its quantification.

The charcoal market in Africa is an informal economy. This enables millions of people to earn a living producing, selling and trading charcoal, due to low barriers to market entry. However, research and policy on charcoal has long focused on the downsides of informality. Informal charcoal production is commonly linked to criminality, an undermining of social cohesion, poor working conditions and most of all, forest loss. These negative perspectives continue to shape our approaches to charcoal markets, despite a recent reframing of charcoal as a potential sustainable development opportunity. Th

The service life of charcoal cartridge has been found to be affected by many factors, including assault agent, concentration, temperature, humidity and flow rate through the cartridges. Therefore, a filter unit was normally placed in front of the cartridges to protect the charcoal from contamination. However, in the practical situation, organic vapors often accompany aerosol particles. Due to the air resistance caused by the filter media, the filter u

Through the water washing process, the porous bamboo charcoal / PVA fiber was prepared. It showed that the viscosity of spinning solution increased with the content of bamboo charcoal increased, but decreased with the content of modified starch increased. The dissolved ratio of modified starch / PVA (60 / 40) blend fiber was highest among all samples. The SEM observation indicated that the s

碩士<br>國立勤益科技大學<br>資訊工程系<br>106<br>Charcoal Painting is an ancient Chinese folk art , also known as ‘’Tanhua’’.Tanjinhua is actually derived from ink art , and the difference between these two is that ink art is more like ‘’water-based ‘’painting technique , in simple terms , water is the main element of ink art , On the other hand , Tanhua use ‘’dry ‘’ skill to accomplish the whole work . Tanhua were the rage of the 1950~1960s after post-war Taiwan, it has been paying more attention by artists not only because it's a trend but also a good way to make a living with it.During the same period,

碩士<br>逢甲大學<br>航太與系統工程所<br>100<br>In this research, the epoxy resin is used as the matrix, and bamboo charcoal was used as the additive. The goal is to find the influence of adding bamboo particles and the carbonization on the microstructure and mechanical properties of the composite. The compression, impact, three-point bending, heat preservation and abrasion tests were carried out for all material samples. Microstructures of the samples were conducted by using optical microscopes, scanning electron microscopes, and a thermal camera. The influence of dispersion and the material behavior was in
