RIBEIRO, Alessandra M.; MACHADO JUNIOR, Hélio F.  e  COSTA, Dilma A.. Catalytic cracking of polyethylene under refinery conditions: production of combustible fractions. Polímeros [online]. 2006, vol.16, n.4, pp.312-318. ISSN 1678-5169.  http://dx.doi.org/10.1590/S0104-14282006000400011.

This work was carried out in an unit of microactivity test, to study the process of combined feeds of low density and high density polyethylenes with vaseline and commercial FCC catalysts (of low and of high activities), to evaluate the production of fuel fractions (gasoline, diesel and residue). The combined feeds of PEBD and PEAD/vaseline, at different concentrations, were processed under refinery conditions. For feeds of PEBD/vaseline at 2, 6 and 10% w/w, production of the gasoline fraction was favored with the high-activity catalyst, while for the PEAD/vaseline feed at 2%, in the production of the same fraction, the low-activity catalyst presented better performance. For all the combined feeds, in all concentrations, the inert material showed better performance for the production of residue fraction, indicating the preferential occurrence of thermal cracking.

Palavras-chave : PEBD; PEAD; fluid catalytic cracking; FCC catalyst; gasoline fraction.
