\"Biogasol\"<\/a>                  Le danois BioGasol est une start-up, de l’Universit\u00e9 Technique<\/u> du Danemark \u00e0 Lyngby, qui a d\u00e9velopp\u00e9 un proc\u00e9d\u00e9 de conversion de compos\u00e9s lignocellulosiques en \u00e9thanol. Son proc\u00e9d\u00e9 optimise le taux de conversion de la lignocellulose et minimise les rejets par un recyclage des effluents. L’am\u00e9ricain Pacific Ethanol qui apporte son aval industriel, alli\u00e9 \u00e0 BioGasol et un consortium d’Universit\u00e9s am\u00e9ricaines prestigieuses "Joint Bioenergy Institute" vient d’obtenir une aide du Department of Energy de plus de 24 millions de dollars.<\/p>\n

\"Biogasol\"<\/a>                                                                                                      Cette aide doit permettre \u00e0 Pacific Ethanol de construire une unit\u00e9 pilote de d\u00e9monstration de production industrielle d’\u00e9thanol \u00e0 partir de biomasse dans son usine de Boardman, dans l’Oregon. Ce pilote devrait produire 250 barils par jour d’\u00e9thanol (2.5 M gallons\/an), on est loin des volumes industriels.<\/p>\n

Le proc\u00e9d\u00e9 Biogasol pr\u00e9sente quatre \u00e9tapes essentielles:<\/p>\n

    \n
  1. une explosion des fibres \u00e0 la vapeur oxydante \u00e0 170-200\u00b0C<\/li>\n
  2. une hydrolyse enzymatique de la cellulose \u00e0 32\u00b0C<\/li>\n
  3. une hydrolyse enzymatique des xyloses \u00e0 70\u00b0C<\/li>\n
  4. une digestion ana\u00e9robique produisant du m\u00e9thane, utilis\u00e9 comme source d’\u00e9nergie.<\/li>\n<\/ol>\n

    Les liquides sont recycl\u00e9s et 15% de la masse initiale sont r\u00e9cup\u00e9r\u00e9s sous forme de solide pour \u00eatre br\u00fbl\u00e9s ou recycl\u00e9s.<\/p>\n

                              Ce contrat met, une fois de plus, en \u00e9vidence le dynamisme de la R&D danoise qui n’h\u00e9site pas \u00e0 relever les manches pour d\u00e9velopper des proc\u00e9d\u00e9s industriels et mettre les bras dans le cambouis. On est loin des \u00e9lucubrations de nos esth\u00e8tes du CNRS.<\/p>\n

    \"Peix_2\"<\/a><\/p>\n

                Pacific Ethanol (PEIX) est une Soci\u00e9t\u00e9 dont les cours varient de fa\u00e7on assez erratique, oscillant entre 4$ \u00e0 9$ en quelques semaines en fonction des al\u00e9as du business du bio\u00e9thanol aux USA. Rester \u00e0 l’\u00e9cart, sauf si vous recherchez des \u00e9motions fortes.<\/p>\n
