Impact of hydrogenation on miscibility of fast pyrolysis bio-oil with refinery fractions towards bio-oil refinery integration

In particular, a straw-based Ablative Fast Pyrolysis (AFP) oil was upgraded via hydrotreatment (HDT) in order to be used as blending component with fossil-based intermediates. The raw pyrolysis is characterized by H/C = 0.14, O/C 0.58 and C 57.73 wt%, while the HDT has 0.016 85.85 wt%. Based on density, viscosity composition, association typical refinery, possible petroleum refinery entry points for include Straight Run Gas-Oil (SRGO), Atmospheric Gas-oil (GO), Fluid Catalytic Cracking Light Cycle Oil (LCO) Heavy (HCO), well Vacuum (LVGO). To that aim, this work examined bio-oil blends aforementioned candidate streams at 30:70 v/v ratio (raw or bio-oil/petroleum stream) respect their miscibility, comparing blend components’ properties, microscopic observation, interfacial tension analysis. From addition of all candidates renders homogeneous mixture where two phases cannot distinguished. addition, no observed blends, different not only did deteriorate fuel characteristics over original stream, but also it improved them, some cases. general, found miscible streams, extending potential further investigation stabilized integration refineries.
