Abstract:
This thesis is concerned with an investigation into methods for the conversion into products which could be used us a chemical feedstock or energy resource. It deals with the conversion of seaweed to oil by the use of elevated temperature and elevated temperatures and pressures. The products of seaweed pyrolysis at various temperatures between 300 and 800°C were investigated. The main products, as identified by Can chromatography and mass spectrometry, from the various gas and liquid fractions are detailed. The differences in products and yields encountered when the seaweed was treated to extract alginic acid before pyrolysis were investigated. The research leads into the use of elevated pressures of reducing gases together with elevated temperatures for seaweed conversion. The use of carbon monoxide and water as the reducing atmosphere at various temperatures and pressures, in the presence and absence of alkaline catalysts and organic solvents, was investigated, with a preliminary examination of the products formed.
