Biomass pre-treatment and production of intermediates (part 2)
Effects of Acid Doping on Biomass Ash Composition During Washing Pre-Treatment With Aqueous Fraction from Wood Htc
Short Introductive summary
The current study is aimed at investigating the feasibility of doping the HTC aqueous fraction with varying ratios of organic acids to enhance the ash removal efficiency when this fraction is used as a washing agent for biomass washing pretreatment. The ash content of the washed biomass and the composition of main ash-forming elements in both the washed biomass and the used washing agent will be evaluated to ascertain the feasibility. The novelty of this study lies in developing a potential valorisation route for a fraction often regarded as waste, while simultaneously reducing the use of a scare resource and potentially minimising operational costs.
