Abstract

Abstract Bio-oils are a promising renewable and carbon-neutral hydrocarbon material that can become a new energy source. Bio-oil mixtures have complex multi-component composition consisting of the pyrolysis products of cellulose, hemicellulose, and lignin of various molecular sizes with a range of highly oxygenated functional groups. Chemical characterization of bio-oil components is therefore necessary to inform the upgrading process of bio-oil and improve its commercial viability. We utilize aerosol technology to facilitate characterization of bio-oil components resulting in compositional differences specific to its volatility-separated fractions. We aerosolize bio-oil mixture, followed by size separation and collection of obtained particles using a cascade impactor, where the collected particles are exposed to sequentially reduced pressures at each of the impaction stages. We characterize components of the impactor separated bio-oil fractions using high-resolution mass spectrometry equipped with interchangeable electrospray ionization and dopant-assisted atmospheric pressure photoionization sources. Through examination of the detected chemical species in each of the separated fractions and assessment of their physiochemical properties, we identify a range of fuel-like aliphatic species with low O/C ratio and low viscosity in the most volatile fraction. The less volatile fractions contained progressively higher portions of more viscous species containing lignin and sugars moieties with characteristic high O/C values. We show that the impactor-based separation of bio-oil fractions facilitates comprehensive characterization of its components with varying fuel viability, capable of guiding upgrading processes.

期刊介绍： Aerosol Science and Technology publishes theoretical, numerical and experimental investigations papers that advance knowledge of aerosols and facilitate its application. Articles on either basic or applied work are suitable. Examples of topics include instrumentation for the measurement of aerosol physical, optical, chemical and biological properties; aerosol dynamics and transport phenomena; numerical modeling; charging; nucleation; nanoparticles and nanotechnology; lung deposition and health effects; filtration; and aerosol generation. Consistent with the criteria given above, papers that deal with the atmosphere, climate change, indoor and workplace environments, homeland security, pharmaceutical aerosols, combustion sources, aerosol synthesis reactors, and contamination control in semiconductor manufacturing will be considered. AST normally does not consider papers that describe routine measurements or models for aerosol air quality assessment.
