Cellulose is a natural substance, macromolecular, non-toxic, renewable and biodegradable origin, whose chemical structure can be modified by replacing the hydroxyls present on the macromolecule and thus obtain products with varying properties of use. With increasing worldwide attention to environmental pollution, obtaining new products from chemical cellulose modification has been carried out with increasing applicability in various industries among them the extraction and production of oil industry. This study shows the action of a surfactant substance obtained from sisal cellulose xanthates (Agave sisalana) modified with lauric alcohol, in laboratory bench, the heavy oil waxing phenomenon through the appearance initiation temperature measurement paraffin crystals (TIAC) and flow activation energy. The results of these experiments showed that this did not reduce the TIAC values in heavy oil sample in question but promoted reduction of up to 8 kJ /mol in the flow activation energy for paraffin oil additivated with modified cellulose in the presence of brine 1000ppm.Downloads
