A general schematic of a pyrolytic process is shown in Figure 1. As shown in Figure 1, the first step in the treatment process is the excavation of the contaminated soil, sludge, or sediment. Oversized rejects such as large rocks or branches are removed and the material is transferred to the ,pyrolysis, unit.

1/7/2006, · The use of conventional electrical heating in the ,pyrolysis, of sewage sludge produced an ,oil, that could have a significant environmental and toxicological impact. Conversely, microwave ,pyrolysis, still preserved some of the functional groups of the initial sludge such as aliphatic and oxygenated compounds, whereas no heavy PACs were detected.

Pokorna et al. reported a maximum bio-,oil, yield of 57.5 wt% with water content as low as 10 wt% when flash ,pyrolysis, was conducted at 500 °C in a lab-scale semi-,continuous, reactor. Likewise, up to 48.5 wt% of bio-,oil, was reported when flash ,pyrolysis, of dried primary sludge and anaerobically digested sludge was investigated by Alvarez et al. [ 87 ] in a conical spouted bed reactor.
