  • Evaluation of the energetic potential of sewage sludge by characterization of its organic composition

    The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also possible to calculate the heating value via chemical ...

  • Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends

    Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

  • Studies on behaviour of a DI diesel engine fuelled with bio oil biodiesel emulsions

    This paper discusses the results on the use of Jatropha methyl ester (JME) - Wood pyrolysis oil (WPO) emulsion as an alternative fuel in a compression ignition (CI) engine. Three different emulsions were prepared by adding WPO in 5%, 10% and 15% by volume with JME 95%, 90% and 85% by volume respectively using a surfactant Span 20 at 4% on volume basis. The engine behaviour in terms of the ...

  • Sulfate ion (SO42−) release from old and new cation exchange resins used in condensate polishing systems for power plants

    In this study, a dynamic cycle test, a static immersion method and a pyrolysis experiment were combined to examine the characteristics of SO42− released from several new and old cation exchange resins used in condensate polishing systems for power plants. The results show that the quantity and velocity of SO42− released from new and old resins tend to ...

  • Bio-oil upgraded by catalytic co-pyrolysis of sawdust with tyre

    We have investigated the improvement in the quality of bio-oils by catalytic co-pyrolysis of sawdust and tyre mixture in an integrated reactor. The vapours from co-pyrolysis are allowed to pass through a desulfurising layer composed of zinc oxide and then through the catalytic layer consisting of silver (Ag), palladium (Pd), molybdenum (Mo), or vanadium (V) supported over SBA-15 or HZSM-5. The ...
