Abstract:

Charcoal consists mostly of carbon materials prepared by carbonization, i.e., traditionally by pyrolysis [1,2] of wood pieces in a kiln. At a high enough temperature and an absence of oxygen [3], high-quality charcoal with low resistance can be produced. A possible application of the low-resistivity charcoal is as an electrode material for electrochemical devices. In this research, bamboo waste was used to produce low-resistance bamboo charcoal. During heating, the temperature gradually increased up to 700°C, was kept approximately constant overnight, and was left to cool down to room temperat

Abstract:

Activated wood charcoal (Carbonized) acts as an excellent adsorbent and it finds wide applications. The present study was carried on four different activated wood charcoals Salix (Sac), Pinus (Pac), Anacardium occidentale (AOac) and Calophyllum inophyllum (CIac) found in Karwar district, Karnataka, India. The activated charcoal was prepared by carbonizing in a muffle-furnace at 800 0 C and the yield of carbonized carbon was about 50%. SEM morphology and EDX spectrum indicates the homogeneity and purity of the activated wood charcoals containing 65-86% carbon to that of commercial charcoal (89%

AbstractConverting biomass to charcoal produces physical and chemical changes greatly increasing environmental recalcitrance, leading to great interest in the potential of this carbon form as a long-term sequestration strategy for climate change mitigation.

In comparison to conventional reductants (i.e., petroleum coke, coal and metallurgical coke), charcoal has a low density, low mechanical properties and high CO2 reactivity, which are undesirable in ferroalloy production

Abstract:

The aims of this article are, first, to investigate the middle- and upper-Holocene woodland history along the altitudinal gradient between the lowlands and uplands of Central Europe (190–550 m a.s.l.) and, second, to outline possible biases inherent in the charcoal record based on a comparison with the pollen record and its known biases. Our anthracological data set contains 42,547 determinations made in 120 charcoal samples taken at 69 sites. The lowest elevated part of the study region (below 200 m a.s.l.) is characterized by the long-term presence of a species-rich hardwood forest (mixed oa

The raw biomasses samples were carbonized under the same conditions and some combustion characteristics of the obtained biochar such as lower calorific value, energy per unit volume associated to bulk density, ash content, moisture content and ash mineral c

This study investigated the implications of charcoal production and consumption in Osun State, Nigeria, particularly its impact on climate change and biodiversity. Data collection was done using a quantitative survey methodology and analysed using descriptive analysis. Four hundred (400) questionnaires were distributed across three senatorial districts in Osun State where three local government areas were randomly selected in each senatorial district and respondents’ perceptions of charcoal’s production and consumption on environmental impact were assessed.

Abstract:

Burns of the hands and feet caused by injudicious disposal of burning charcoals is a previously unreported cause of burn morbidity and occurs not infrequently in children in Hawaii and, likely, in other resort communities. Because burns of the hands and feet often result in need for long-term rehabilitative therapy and often serious functional loss, recognition by the pediatric community of this totally preventable problem is an important component of health and safety education. Charcoal burns in infancy generally results from improper disposal of used coals and could be completely avoided by

Charcoal was the residue of the decomposition of wood from heating process whereas the chemical component was carbon. One of the charcoal production methods used was a kiln drum with carbonisation mixed system. This research aimed to identify and analyse the quality of teak wood charcoal made by carbonisation mixed system with the addition of sawdust teak using kiln drum method. Teak wood pieced in 5-10 cm diameter were charred by the addition of sawdust (70:30) to maintain the temperature process ranged between 4000C and 4500C.

Abstract The Brazilian Amazon is vastly deforested by unsustainable practices. Several species of trees are threatened by extinction and their exact number is hard to quantify. Federal laws prohibit the harvest of endangered forest species. It is a vast challenge to control the illegal trade of wood and especially charcoal in Brazil. The goal of this work is to contribute to an identification database. It presents the anatomy of wood and charcoal of Bertholletia excelsa, Hevea brasiliensis and Swietenia macrophylla. Structural modifications due to carbonization were also studied. One Eucalyptu

Luzia woman is considered one of the oldest Paleoindian skeletons found in the Americas. Luzia was found at the Lapa Vermelha IV site (Lagoa Santa, Minas Gerais, Brazil) in 1975 by the archaeologist Annette Laming-Emperaire (1917–1977) who sent to the Gif laboratory charcoals collected in the vicinity of the skeleton for radiocarbon dating. Twenty-nine charcoal samples were dated from different levels of the stratigraphy of the cave (Délibrias et al. 1986). Recently, new charcoal samples were discovered within Laming-Emperaire's correspondence and were subsequently dated by the Saclay AMS labo

Abstract:

Good quality activated charcoals were prepared from areca nutshell and coconut shell using phosphoric acid as a chemical activating agent at 400oC. Physico-chemical properties like iodine number, methylene blue number, and surface area of two activated charcoals were measured to assess the porous nature. A special test called acetic acid number was devised to understand the quality of functional groups on charcoal surfaces. Proximate analysis and physical properties of the two activated charcoals closely matched those of a commercial sample, confirming the good quality of samples prepared in t

Abstract:

Cameroon harvests a considerable volume of round wood each year, only a small part of which is used for manufactured products. In recent decades, various charcoal-making initiatives have emerged around industrial timber-processing units, particularly in the eastern region, in order to develop a market for residual biomass. However, the undifferentiated use of these residues obtained from different species often results in products with varying energy potential that are not always appreciated by consumers. Moreover, the physical and chemical characteristics of the charcoal produced are unknown,

ABSTRACT Tropical tree floras are highly diverse and many genera and species share similar anatomical patterns, making the identification of tropical wood charcoal very difficult. Appropriate tools to characterize charcoal anatomy are thus needed to facilitate and improve identification in such species-rich areas. This paper presents the first computer-aided identification key designed for charcoals from French Guiana, based on the wood anatomy of 507 species belonging to 274 genera and 71 families, which covers respectively 28%, 67% and 86% of the tree species, genera and families currently l
