- Abstract
- Pyrolysis oil (PO), derived from biomass through fast pyrolysis process have the potential to displacesignificant amounts of petroleum fuels. The PO derived from wood has been regarded as an alternative fuel to be usedin diesel engines. However, the use of PO in a diesel engine is very limited due to its poor properties like low energydensity, low cetane number, high acidity and high viscosity of PO. Therefore, one of the easiest way to adopt PO todiesel engine without modifications is blended with other fuels that have high centane number. However, PO that hashigh amount of polar chemicals is immiscible with non polar hydrocarbons of diesel or biodiesel. Thus, to stabilize ahomogeneous phase of diesel/biodiesel-PO blends, a proper surfactant should be used. Nevertheless, PO which wasproduced from different biomass type have varied characteristics and this complicates the selection of a suitableadditive for a specific PO-diesel emulsion. In this regard, a more simple approach such as the use of a co-solvent likeethanol or butanol to induce a more stable phase of the PO-diesel mixture could be a promising alternative. In thisstudy, a diesel engine operated with diesel/biodiesel-PO-butanol blends was experimentally investigated. Performanceand gaseous & particle emission characteristics of a diesel engine were examined under the engine loads of IMEP 0.2 ~0.8MPa.
