Resumen
It is estimated that world's supply of fuel will increase globally so its production will help address the growth in consumption. Cuba is not an exception in this world trend. The present work has the general objective to introduce the projection of the research to perform a thermo-economic assessment of the conversion of Cuban sugar cane lignocellulosic residues by pyrolysis processes to obtain maximum yields of liquid fuels with low cost. In Cuba, the main renewable energy sources are concentrated in biomass with 2,027,530 toe (99.3%). Biomass fuels and residues can be converted to more valuable energy forms via a number of processes including thermal, biological, and mechanical or physical processes. There are some relevant comments to be considered in thermo-chemical conversion of biomass to obtain liquid biofuels: investors need to know the most appropriate conversion method for each feedstock in particular; it is essential to improve the understanding of the process, leading them towards the optimization and explaining the variation in performance between feedstock, process parameters and operating scale, also there are technical barriers in the environmental performance; sometimes it is even confusing and frustrating to comprehend the details and validity of the techniques and to make a decision on a method to use for a certain type of biomass or a combination of different biomass types. The authors add that the selection of these alternatives is based mainly in the analysis of the type of energy, process optimization or economic studies without the integration of them, making the right choice are hard to get. Availability, dedicated fuel handling and logistic systems are needed to take them into account in the process of selection. To achieve the proposed objective will be obtained the kinetic model for the pyrolysis of sugar cane lignocellulosic residues, develop processes for the production of bio-oil with lignocellulosic materials derived from sugar cane, test the bio-oil derived from the pyrolysis of sugar cane lignocellulosic residues as fuel for internal combustion engines, develop a plant model of fast pyrolysis of sugar cane lignocellulosic residues, and develop a procedure of thermo-economic assessment.
