Book Description
Sub-Saharan West Africa lacks of natural resources, especially for energy production. By-products of agro-industry as cashew nut shells (CNS), jatropha (Jc) and shea (Sc) press cakes were identified as available resources for energetic valorisation. These biomasses are characterized by high extractive contents (cashew nut shell liquid/CNSL or triglycerides) which are the reason for toxic fumes during combustion. The thesis investigated the feasibility of flash pyrolysis as alternative process for these resources, more specifically the impact of the extractives on yields, the composition and the stability of flash pyrolysis oils. The feedstock were derived into samples covering the whole range of extractive contents (from de-oiled press cakes, ~0 wt%; to pure extractives, 100 wt%) which were characterized and pyrolysed in two laboratory devices (TGA and tubular furnace), then by applying flash pyrolysis conditions in a fluidized bed reactor. No significant interaction in-between the solid matrix and the extractives during pyrolysis were observed but different products were identified. CNSL volatises between 250 and 320°C, several phenolic compounds and typical compounds of crude CNSL were found to be present in the pyrolysis oil. In contrast, triglycerides are entirely decomposed at 380 to 420°C to give linear hydro-carbon chains. Some interaction products of the triglycerides with proteins were identified. Additionally, the experiments with the pilot plant have shown operational difficulties in the fluidized bed, which are linked to specific properties of the press cakes. Thus, further optimisations of process conditions are suggested. To overcome the observed phase separation of the pyrolysis oils mixtures with other biofuels were studied. The obtained emulsions are more homogeneous but the physical stability is still insufficient despite the addition of surfactants.

Book Description
Allons-nous trouver une prometteuse "énergie nouvelle" dans l'une des plus anciennes formes d'énergie exploitées par l'humanité ? Les végétaux - la "biomasse", dit-on aujourd'hui - constituent un important réservoir énergetique que les techniques modernes rendent à nouveau utilisable.Sous-produits agricoles (pailles), déchets, bois et forêts, cultures nouvelles spécialisées (canne de Provence), de multiples sources d'énergie verte existent. Les procédés d'exploitation se diversifient, s'améliorent et se répandent dans les fermes, les HLM, les usines, les transports.Par-delà d'importantes économies d'énergie, c'est à un remodelage complet de l'agriculture, de son milieu social, que peuvent conduire ces développements.La biomasse, une chance à saisir ?
L'Energie, un nouveau marché pour l'agriculture?
