Critical factors for operation of internal combustion engines on raw bio-oil

Fernando Preto, Executive Director, Canadian Bioenergy Association


Fernando Preto received his B.A.Sc. in Chemical Engineering from the University of Toronto and his Ph.D. from Queen’s University at Kingston. Following graduation, he joined the Canadian Combustion Research Laboratory to pursue research on reducing emissions from combustion systems. He followed this up with research projects on fluidized bed processing, small scale power generation from difficult fuels and conversion of biomass at Natural Resources Canada (NRCan). During 2013 he served as the Executive Director of the Canadian Bioenergy Association (CanBio). He is currently Team Leader for Thermal Conversion of Biomass at NRCan’s CanmetENERGY laboratories in Ottawa, Canada.

About the speech:

One of the major barriers to accelerating the pyrolysis technologies into heat and power applications is the problematic properties of the liquid product. These include, but are not limited to: homogeneity, solids content, viscosity, stability, ash, heating value, acidity and water content. Because of these properties, utilization issues are often experienced if pyrolysis liquids are utilized in the same equipment that is used for conventional fuel oils. Thus, although at the current state of technology, fuel production costs may make pyrolysis oil competitive with fuels oils commercial applications are impeded by the additional cost and retrofitting required and the uncertainty surrounding the use of fast pyrolysis liquids.
