In the current energy context, biomass is a promising energy source because its use generates low carbon dioxide emissions and its nature is renewable. There are several processes for the use of this energy source, among which combustion, gasification, and pyrolysis stand out. However, the use of this biomass in its natural state has disadvantages that reduce the thermal efficiency of the processes, due to the properties of biomasses, such as low energy density and high humidity. To reduce these disadvantages, energy densification processes have been studied to produce pellets and briquettes with better properties; however, in most cases, it is necessary to add a binding agent in the densified biomass to improve the adhesion of the particles, such agents could negatively affect the energy utilization process [1].

On the other hand, in Colombia the oil palm industry is one of the most representative sectors of the economy, contributing 11% of the gross domestic product of the agricultural sector, being crude palm oil and palm kernel oil the main commercial products of this industry, which have several applications in which edible oils, food, cosmetics and biofuels stand out. Parallel to this process, high proportions of palm oil fibers and shells are generated as residues; this is estimated that 40% by weight of a fresh fruit bunch corresponds to these residues, so in recent years alternatives for their utilization have been investigated, being energy utilization an alternative with high potential [2].

The objective of this work was to study, by thermogravimetric analysis, the effect of binders on the kinetic parameters of the thermal degradation of densified palm kernels. For this purpose, two types of binders were studied: starch as a natural binder and sodium acetate as a synthetic binder in two proportions, 5%, and 10%, compared with biomass without binder. The results show that 10% acetate improves the reference time of the process, while starch in proportions of 5% has a low impact on the process.
