the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

Introduction. The aim of this investigation is to prepare activated carbons with good sorbent characteristics from oil-fired fly ash, looking for suitable activation processes to produce surface sites with high reactivity on the carbonaceous matrices [1-4]. In particular, the nitrogen surface sites, formed by gaseous ammonia reaction at 800°C, could greatly increase the adsorption of gaseous sp...

Dyes are widely used in various industries such as those involving paper, food, plastics, and fibers. The produced wastewater has a specific character. Organic substances found when introduced into natural water bodies have toxic effect on living organisms, causing increased chemical biological oxygen demand. Some dyes, even very low concentrations, cause intense colouring. To remove dyes from ...

Two codes of Bureau of Indian Standards, viz., IS 2752:1995 and IS 8366:1989 are available for classification of adsorbents for their use in specific purposes based on their physico-chemical characteristics. No IS code is available for directly assessing the suitability of activated carbon for contaminated water treatment. Two specific categories of activated carbons prescribed in the above IS ...
