In the context of Fuel Injectors the so-called lignocellulose bio-refinery, the coconut shell (S) and pulp (P) of Acrocomia aculeata (Arecaceae) are interesting agro-industrial wastes that can be used as feedstock for the production of high value-added products.The aim of this work was to evaluate these lignocellulosic residues S and P, to obtain the microcrystal (MCC) and microfiber (MFC) of cellulose, and to characterize them to propose possible applications.First, cellulose content in the raw materials was determined, being 39.69% and 45.

42% for both (S and P)) respectively, respectively.Then, the purification of residues was carried out via alkaline and bleaching treatments.Next, in order to obtain MCC and MFC from the purified cellulose, a chemical treatment with HCl (for MCC) and a mechanical treatment with a blender (for MFC) were performed.The size and morphology were observed via MEB, and properties were characterized using Weight Control Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and differential thermogravimetric analysis (DTG).
