Hydrothermal liquefaction of 11 biomasses and their co-liquefaction mixtures show how product composition depends on feedstock biochemical components, while nitrogen and oxygen distribution is controlled by carbohydrate and protein interactions.
ABSTRACTThe course of the initial set reactions of Portland cement-PFA blends is markedly influenced by the presence of fly ash. Data are presented on the effect of two Class F PFA materials blended with cement in 30:70 ratio. Selected analyses of the aqueous phase compositions at lh to 336h are presented. During the first 6h a nearly steady state aqueous phase composition is achieved with respect to Na, K and Ca concentrations. Following a renewed burst of hydration activity, Ca decreases rapidly in the interval 6–24 h while Na and K contents rise more gradually.
