Abstract
Biomass plays an important role due to its abundant availability, as well as being completely renewable and presented low cost. The liquefaction process consists of transforming the biomass in the form of large and small solids into bio-oil that can be used as a liquid biofuel. The excessive increase in aquatic plants impairs the energy generation in hydroelectric plants, since their accumulation in the grids leads to a decrease in water intake through the turbine as well as to a greater pressure on the grates, which may deform or break them, making the generation unit's operation unavoidable. Thus, the present work aims to study the conditions to be adopted in order to carry out the liquefaction process via solvolysis of the invasive aquatic plant Egeria densa. It was found that the highest yield was obtained when the reaction medium was stirred for 60 minutes at 130 ° C. For a constant temperature the increase in the reaction time causes an increase in the liquefaction yield and for the constant reaction time an increase in the temperature leads to an increase in the liquefaction yield. In general, the results indicate that it is feasible to use Egeria densa for bio-oil production.
