Resumen

Pyrolysis has proven to be one of the more suitable technologies for valorization and exploitation of municipal solid wastes at industrial scale. Nevertheless, industrial scale implementation of this process requires the liquid product to be of suitable characteristics as a fuel. In order to fulfil this aim, dehydrogenation, deoxygenation and catalytic cracking are the common processes to be carried. Deoxygenation and catalytic cracking are carried out on acid catalysts, mainly on zeolite based catalysts, either of small (HZSM-5) or big (HY, β) pores. Catalytic pyrolysis may be carried out following several strategies. Thus, the catalyst may be used in the reactor itself mixed with the raw material (in situ), it may be used in a bed placed at the outlet of that of thermal cracking (a posteriori) or it may be used in another unit in order to crack the liquid obtained by thermal cracking. In this paper, the advantages and disadvantages of these strategies will be analysed for the case of pyrolysis of plastics by using catalysts based on zeolites.
