Abstract

The research consisted in cultivating the alga B. braunii in an open air pilot installation in order to see if it is possible to make it produce important quantities of hydrocarbons. A culture installation was developed for the culture of this alga at pilot level (500 l tanks). The mass culture experiments mainly demonstrated that: 1. the alga is capable of growing in open air from April to October (temperature between +- 8 degrees C and 32 degrees C); 2. the B. braunii culture is rapidly contaminated (2 to 3 weeks after seeding) by other species such as Scenedesmus and Chlorella. No correlation was established between the moment the contamination appeared, and temperature or rainfall; 3. the culture's hydrocarbon outputs do not exceed 10% as compared to the dry weight of the algae. The essence of the research consisted in the description of the evolution of the culture (number of cells, rainfall, temperature, culture medium analysis, etc...), as well as in finding means to avoid the proliferation of algae contaminating the culture and to increase the hydrocarbon production of B. braunii. These means as well as experiments aiming at the valorization of algae of which the hydrocarbon have been extracted and their qualitative analysis are described in the present report.
