Influence of Hydrothermal Treatment of Macro-Algae on Alkali Metal Content of Products

K. Anastasakis & A.B. Ross
Macro­algae (seaweeds) are biomass from a marine environment that represents an alternative source of feedstock with potential advantages compared with traditional terrestrial biomass. They have faster growth rates, higher photosynthetic activity; they do not compete with food crops or require valuable land space for cultivation. Thermo­chemical processing of macro­algae pose two main drawbacks, firstly they have a high moisture content (usually about 90wt%) and secondly they contain very high levels of ash in particular alkali...
