Abstract:
... The products from fast pyrolysis of biomass are variable and highly dependent upon feedstock composition, particle size and geometry, and operating conditions such as heating rate, reaction temperature, and sweep gas composition and velocity. Microwave heating is internal to the biomass particles, thereby avoiding convective and conductive heat transfer limitations, which facilitates decoupling he ...

Abstract:
... Inorganic compounds in biomass, often referred to as ash, are known to be problematic in the thermochemical conversion of biomass to bio-oil or syngas and, ultimately, hydrocarbon fuels because they negatively influence reaction pathways, contribute to fouling and corrosion, poison catalysts, and impact waste streams. The most common ash-analysis methods, such as inductively coupled plasma-optical ...
