Pyrolysis process of waste oily sludge termocatalu00edtica oil using nanostructured materials

摘要

"The process of pyrolysis termocatalu00edtica D waste oily sludge of oil using nanostructured materials the present invention consists in developing a process for the pyrolysis of sludge termocatalu00edtica oily oil, use 'nanostructured aluminum silicate Acid as catalysts, for the processing of waste generated in the industry of etru00f3leo.The catalysts were synthesized by hydrothermal method using sources of aluminum, silicon, the conductorof structural and water as the diluent.The characteristics of the catalysts, determined by X-ray diffraction and specific surface area have shown that the materials are typically nanostructured and size of pores in the range of 2 to 5 nm and specific surface area in the range of 700 to 900 m2 / g. the 'res of acidity of Ca Talisadores ranged from 1.5 to 2 mmol / g.In the process of pyrolysis termocatalu00edtica, catalysts of aluminium silicate was added to the residue in proportions ranging from 5 to 20% by mass, and ubmetidos heating at temperatures ranging from 500 to 600 C, using nitrogen as gas drag. The temperature of the pirolisador hi is controlled by a thermocouple pyrometer coupled to inserted in the reactor.The products reacionais were condensed, cooled and analyzed by Cr matografia and gas mass spectrometry. The thermal pyrolysis produced hydrocarbons in wide range of C17 to C42.The nanostructured catalysts synthesized showed activities for onversu00e3o residue of oily residues under the conditions evaluated, with seal ividade for obtaining hydrocarbons in diesel oil, in the range of C11 - C2.
