Slash and Char
The existence of an anthropogenic and carbon (C) enriched dark soil in different parts of the world and especially in Amazonia (Amazonian Dark Earths (ADE) or Terra Preta de Índio) proves that the predominant Ferralsols and Acrisols can be transformed into fertile soils. Charcoal formation and deposition in soils seems to be a promising option to transfer an easily decomposable biomass into ref...
متن کاملInfluence of Pyrolysis Temperature on Rice Husk Char Characteristics and Its Tar Adsorption Capability
A biomass waste, rice husk, was inspected by thermoanalytical investigation to evaluate its capability as an adsorbent medium for tar removal. The pyrolysis process has been applied to the rice husk material at different temperatures 600, 800 and 1000 °C with 20 °C/min heating rate, to investigate two topics: (1) influence of temperature on characterization of rice husk char and; (2) adsorption...
متن کاملHeterogeneous Destruction of Nitrous Oxide by Char
Reduction of N2O by chars from subbituminous Siersza, Piast and Janina coals have been studied in a pressurised reactor at 973 1173 K. It has been found that the reaction N2O + [C] N2 + [CO] is controlled both by the chemical kinetics and diffusion of N2O within char particle's pores. The rate constant of the above reaction has been found to be independent of pressure within the examined range ...
متن کاملCarbon Dioxide Gasification of Kraft Black Liquor Char in a Laboratory Char Bed Reactor
In the current study a series of pyrolysis and CO2 gasification experiments were conducted on a bed of kraft black char under a perpendicular impinging jet. The experiments demonstrated that the char bed carbon gasification rates are externally mass transfer limited. The mass transfer is further decreased by a net molar out-flow caused by the conversion of one mole of reactant CO2 to two moles ...
متن کاملPreparation of porous bio-char and activated carbon from rice husk by leaching ash and chemical activation
Preparation porous bio-char and activated carbon from rice husk char study has been conducted in this study. Rice husk char contains high amount silica that retards the porousness of bio-char. Porousness of rice husk char could be enhanced by removing the silica from char and applying heat at high temperature. Furthermore, the char is activated by using chemical activation under high temperatur...
