Deoxidation of Oxidized Coal during Carbonization

Pretreatment of biomass by torrefaction and carbonization for coal blend used in pulverized coal injection.

To evaluate the utility potential of pretreated biomass in blast furnaces, the fuel properties, including fuel ratio, ignition temperature, and burnout, of bamboo, oil palm, rice husk, sugarcane bagasse, and Madagascar almond undergoing torrefaction and carbonization in a rotary furnace are analyzed and compared to those of a high-volatile coal and a low-volatile one used in pulverized coal inj...

Alumina Inclusion Behavior during Steel Deoxidation

A computational model based on classic homogenous nucleation theory, thermodynamic analysis and numerical simulation, has been developed to study steel deoxidation by aluminum in a low carbon aluminum-killed steel ladle, which calculates the nucleation and time evolution of the alumina inclusion size distribution due to Ostwald ripening, Brownian collision and turbulent collision. Starting with...

Effects of Oxidized Brown Coal Humic Acid

Field experiments were carried out during 2011-2014 at the Research and Experimental 13 Center to Combating Desertification located in the Elsen Tasarkhai station of central Mongolia. The 14 study was aimed to identify the effects of oxidized brown coal humic acid fertilizer on the relative 15 growth rate of several trees for forest rehabilitation. The trees used were Populus sibirica, Salix 16...

Biodegradation of Phenol and Emulsification Properties of Native Microorganisms from Coal Carbonization Plant

Phenols (aromatic organic compounds) are commonly occurring organic pollutants in the environment. Some of the toxic effects of phenol in humans are corrosive to eyes, skin and respiratory track, in addition also causes lethal effects in animal and plant community when discharged even in low concentrations. The problem associated with phenol in the environment, is in need to removal such hazard...
