Abstract

يتعلق الاختراع بطريقة لإنتاج الزيت الحيوي انطلاقا من الطحالب الضوئية التغذية وغيرية التغذية التي تتمثل في: زراعة طحلب ضوئي التغذية على الأقل ، في ظل ظروف ذاتية التغذية ، للحصول على تعليق مائي أول من الكتلة الحيوية الطحلبية ، زراعة طحلب غيري التغذية على الأقل في ظروف غيرية التغذية ، للحصول على تعليق مائي ثاني من الكتلة الحيوية الطحلبية؛ إخضاع التعليق المائي الأول للكتلة الحيوية الطحلبية لتركيز للحصول على تعليق مائي أول مُرَكز للكتلة الحيوية الطحلبية؛التوليف بين التعليق المائي الأول المُرَكز للكتلة الحيوية الطحلبية وبين التعليق المائي الثاني المذكور للكتلة الحيوية الطحلبية مما يسمح بالحصول على تعليق مائي ثالث للكتلة الحيوية الطحلبية؛ إخضاع التعليق المائي الثالث للكتلة الحيوية الطحلبية لتركيز للحصول على تعليق مائي ثاني مُرَكز للكتلة الحيوية الطحلبية ؛ إخضاع التعليق المائي الثاني المذكور للكتلة الحيوية الطحلبية لمعالجة حرارية للحصول على مرحلة زيتية تضم الزيت البيولوجي ومرحلة مائية تضم المركبات العضوية.The invention relates to a method for producing bio-oil based on phototrophic and heterotrophic algae, which is represented in: Cultivation of at least a phototrophic algae, under autotrophic conditions, to obtain a first aqueous suspension from the algal biomass, cultivation of heterotrophic algae at least in heterotrophic conditions , To obtain a second aqueous suspension from algal biomass; Subjecting the first aqueous suspension of algal biomass to a concentration to obtain a concentrated first aqueous suspension of algal biomass; synthesis between the first concentrated aqueous suspension of algal biomass and the said second aqueous suspension of algal biomass allowing to obtain a third aqueous suspension of algal biomass; Subjecting the third aqueous suspension of algal biomass to a concentration to obtain a concentrated second aqueous suspension of algal biomass; The aforementioned second aqueous suspension of algal biomass was subjected to a thermal treatment to obtain an oily phase comprising biological oil and an aqueous phase containing the organic compounds.
