Bio-oil production from sewage sludge provides a potential sludge treatment alternative, which shows advantages in both sludge treatment and energy recovery. The related technologies to convert sludge into high quality fuel or synthesized bio-diesel have been widely studied recently. In this paper, major effective technologies of low temperature pyrolysis, direct thermochemical liquefaction, microwave pyrolysis and transesterification had been reviewed. Finally, the advantages and disadvantages of these methods are discussed in detail.

the treatment and disposal of sewage sludge is one of the hot spots in recent years, and the value of its energy utilization has gradually received attention by researchers. In this paper, the concept, yield, harm as well as the conventional disposal methods of sewage sludge are described, three kinds of main technologies of oil making from sewage sludge are introduced, including high temperature pyrolysis, low-temperature pyrolysis and direct thermo chemical liquefaction, and the research progress of these three technologies is reviewed.

Sewage sludge from oil refineries poses special problems in the disposal of solid, and often hazardous waste. Drying followed by low temperature conversion (i.e., pyrolysis at 400°C) renders sludge to fuel oil and char. This process was operated in full scale, using an input of 40 tonnes. An overall oil yield of 35% and a rate of 45% of char referring to the input of dried solids was achieved during the conversion process using a sludge having 16% dried solids concentration. Halogenated organics and PAH present in the the feed sludge were reduced during the conversion process by 98.4% and 83.7% respectively. Mercury was completely removed from the fuel oil and char through adsorption to the residue of oil/water separation (centrifugal sludge). The conversion oil produced meets fuel oil standards and can be used for industrial purposes. The char produced can be used as a reducing agent in steel manufacture.
