“…While there is fundamental work underway (Bridgwater, 1996;Williams & Nugranad, 2000;Wang et at., 2006), more research is necessary to explore the wide range of conventional and unconventional catalysts. Catalytic pyrolysis has been reported to be a productive means to increase gas yield by decreasing the amount of liquid, as well as positively affecting the quality of the organic composition of the oils -in situ upgrading (Domínguez et al, 2003).…”

“…Furthermore, the condensables from microwave pyrolysis contain less carcinogenic compounds than those produced in conventional pyrolysis [55] and the noncondensables have a higher concentration of CO and H 2 (synthesis gas) after microwave pyrolysis than after conventional pyrolysis [56].…”

“…ZnCl 2 had a negative effect on the product's quality. Dominguez et al [18] compared bio-oil characteristics obtained from MAP and conventional pyrolysis. Three types of sewage sludge (two from urban WWTPs and one from a dairy factory) enriched with graphite (0.5-3 g/kg) were used as feedstock.…”

Abstract:Residual sludge disposal costs may constitute up to, and sometimes above, 50% of the total cost of operation of a Wastewater Treatment Plant (WWTP) and contribute approximately 40% of the total greenhouse gas (GHG) emissions associated with its operation. Traditionally, wastewater sludges are processed for: (a) reduction of total weight and volume to facilitate their transfer and subsequent treatments; (b) stabilization of contained organic material and destruction of pathogenic microorganisms, elimination of noxious odors, and reduction of putrefaction potential and, at an increasing degree; (c) value addition by developing economically viable recovery of energy and residual constituents. Among several other processes, pyrolysis of sludge biomass is being experimented with by some researchers. From the process, oil with composition not dissimilar to that of biodiesels, syngas, and a solid residue can be obtained. While the advantage of obtaining sludge-derived liquid and gaseous fuels is obvious to most, the solid residue from the process, or char (also indicated as biochar by many), may also have several useful, initially unexpected applications. Recently, the char fraction is getting attention from the scientific community due to its potential to improve agricultural soils' productivity, remediate contaminated soils, and supposed, possible mitigation effects on climate change. This paper first discusses sludge-pyrolysis-derived char production fundamentals (including relationships between char, bio-oil, and syngas fractions in different process operating conditions, general char properties, and possible beneficial uses). Then, based on current authors' experiments with microwave-assisted sludge pyrolysis aimed at maximization of liquid fuel extraction, evaluate specific produced char characteristics and production to define its properties and most appropriate beneficial use applications in this type of setting.
