Co-products of Jatropha curcas and Moringa oleifera as feedstocks for gasification and pyrolysis

Resumen

Most of the researches over Jatropha curcas biodiesel production are focused on fuel properties of
Jatropha biodiesel, the approaches and techniques used to produce biodiesel, evaluation of physical,
chemical and fuel properties of Jatropha biodiesel and the comparison with biodiesel produced
from other feedstocks, or on environmental impact of Jatropha biodiesel or associated with future
sustainability of Jatropha biodiesel. Nevertheless, less information can be found based on the
potential of Jatropha curcas and Moringa oleifera wastes for gasification and pyrolysis. The scope
of this paper is to make a state of art survey in this particular subject in order to show the real
potential of the co-product of these two biodiesel production feedstocks. The use of the shell and
husk by-products of the biodiesel production process from Jatropha curcas and Moringa oleifera is
not well reported but there are enough reports demonstrating the feasibility of their use and
excellent features as biomass feedstocks for thermochemical conversion. The economic feasibility
of small/medium-scale gasification systems integrated to internal combustion engines using JC
shell for producing electricity is reported. There is more studies respect the use of JC instead of
Moringa. In any case, the implementation of these biomass will depend on disposal, therefore are
only suitable in-situ in located specialized agro industrial facilities at local scale.
