Abstract

The macaúba palm (Acrocomia aculeata) is a palm-seed-oil producing tree of great economic value for its high productivity, and the broad range of possible uses for the different parts of the plant. This palm is one of the most promising species for the production of biodiesel, however, its use generates large amounts of waste. The aim of this work is to produce and evaluate the quality of briquettes made from the epicarp of the macaúba palm, in association with the waste of the Pinus sp. For the characterization of the residues, the following analyses were carried out: bulk density, immediate chemical composition, and higher calorific value. Different treatments were adopted in the production of the briquettes, namely: T1 (100% macaúba palm), T2 (75% macaúba palm + 25% pine), T3 (50% macaúba palm + 50% pine), T4 (25% macaúba palm + 75% pine) and T5 (100% pine). The briquettes were produced at a pressure of 1000 PSI, and at a temperature of 120-130 ºC, press and cooling times of 5 minutes, and an average humidity of 9.88% for the macaúba palm and 8.00% for the Pinus. In order to qualify the briquettes’ dimensions, the following were evaluated: apparent density, rupture load, lower calorific value, useful calorific value and energy density. In general, mixing at least 50% macaúba epicarp is recommended to produce briquettes, as this material provides increased strength and energy density to the product.
