Available in PDF, EPUB and Kindle. Book excerpt: The development of better and efficient methods of consuming less and/or wasting little resource materials is becoming more important. In this study, pyrolytic waste tyre carbon black residue and commercial grade activated carbon were characterized and evaluated against adsorption of mercury vapor. The performance of the raw carbon black residue and the activated carbon against mercury vapor generated in the laboratory was determined using a designed reactor system. The adsorption of Hg+ was investigated at temperatures ranging from 200 to 280¬∞C for 6¬†hours. Batch experiments were conducted for the different carbon residue samples and characterization analysis were done before and after adsorption using the spectroscopic, microscopic, and structural techniques to elucidate the structural arrangements and properties of the carbonaceous materials. Spectroscopic analysis of these carbonaceous residues showed a C=C stretching vibration attributed to the lignocellulose aromatic ring at 1657,Äì2000¬†cm,àí1. Comparatively, it was also observed that the Infrared spectrum of raw carbon black exhibits less functional groups as compared to the H2SO4-AC and H2O2-AC carbonaceous residues prepared.

Available in PDF, EPUB and Kindle. Book excerpt: This book is presented in two parts. Part I covers the problems associated with scrap tires and identifies existing and potential source reduction and utilization methods that may be effective in solving the scrap tire problem. Barriers to increased utilization and options for removing the barriers are indentified and evaluated. Part II provides information on the use of whole, scrap tires and tire-derived fuel (TDF) as combustion fuel, and on the pyrolysis of scrap tires. The use of whole tires and TDF as a primary fuel is discussed for dedicated tire-to-energy facilities. The use of whole tires and TDF as a supplemental fuel is discussed for cement manufacturing plants, pulp and paper mills, and other industrial processes. The focus of Part II is the impact of burning whole tires and TDF on air emissions.

Download or read book A Comparative Study of Tailored Activated Carbon from Waste Tires Against Commercial Activated Carbon F400 for the Removal of Methylene Blue written by Osmary C. Contreras and published by . This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although color represents a non-mandatory water quality standard, organic compounds such as dyes must be removed from wastewater before discharge. Dyes are considered to be aesthetic and toxic pollutants in water. Various water treatment processes have been studied in order to obtain an optimum removal of dyes. Adsorption by activated carbons (ACs) has demonstrated to be the technique of preference. However, the high cost of the precursor material and process for production could influence for its application. Therefore, it is necessary to find raw materials of low cost that requires limited processing and is easily available. In this study, chemical activation of waste tires for developing activated carbons was evaluated. Tires of 400 [micro]m nominal size were impregnated with potassium hydroxide (KOH) in different w/w ratios (0:1, 1:1, 2:1, 3:1, 4:1 and 5:1) and two other parameters were selected in order to obtain the best conditions for the desirable carbon; One is the activation temperature (600, 700 and 800°C) and the second is contact time during activation (1, 2 and 3 h). BET specific surface area and pore size distribution (PSD) for each carbon was determined. The activated carbon from waste tires with higher BET specific surface area and mesopore percentage was obtained with a KOH/tires (2/1), temperature 800°C and activation time 1 h. Adsorption isotherm, kinetic studies and microcolumn experiments were conducted with the selected activated carbon from waste tires (ACWT) and commercial activated carbon (F400) for the removal of methylene blue (MB). ACWT has demonstrated to be an effective adsorbent in removing MB but with lower adsorption capacity than that of F400, suggesting further studies need to be conducted for enhancing the activation process of waste tires.

Download or read book Recent Advances in Pyrolysis written by Hassan Al- Haj Ibrahim and published by BoD – Books on Demand. This book was released on 2020-01-22 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pyrolysis is an irreversible thermochemical treatment process of materials at elevated temperatures in an inert atmosphere. It is basically a carbonisation process where an organic material is decomposed to produce a solid residue with high (or higher) carbon content and some volatile products. The decomposition reactions are accompanied in general with polymerisation and isomerisation reactions. The end products of pyrolysis can be controlled by optimizing pyrolysis parameters such as temperature and residence time. Pyrolysis is used heavily in the chemical industry to produce many forms of carbon and other chemicals from petroleum, coal, wood, oil shale, biomass or organic waste materials, and it is the basis of several methods for producing fuel from biomass. Pyrolysis also is the process of conversion of buried organic matter into fossil fuels.
