Abstract:
In this research, we are analysing the behaviour of the wastes coconut shells of african palm (Elaeis guineensis) when dealing with different gas mixtures and its influence on the development of lattice porous internal and its formation as foam. The study shows that samples worked with water vapour mixtures developed the highest percentage of carbon foam as foams. The greatest expansion of the material occurred when 300 g of precursor, in the presence of steam at a pressure of 2.0 MPa, was introduced into a 1000 mL stainless steel reactor placed inside a sand-bath furnace previously heated to 550 °C. A relationship between the heating rate and degree of foaming was observed with the synthesized materials. An interesting result of this work was the relation established between yield and degree of foaming and between degree of foaming and immersion enthalpy.
