PROCESSES AND SYSTEMS FOR PRODUCING FUELS AND PETROCHEMICAL FEEDSTOCKS FROM A MIXED PLASTICS STREAM
Methods and systems for producing pyrolysis products from a mixed plastics stream are described herein. The method may include conducting pyrolysis of a plastic feedstock to produce a stream of plastic pyrolysis oil; feeding a catalytic cracking feed stream and a catalyst from a catalyst regenerator into a fluidized bed reactor, where the catalytic cracking feed stream comprises the plastic pyrolysis oil; cracking the catalytic cracking feed stream in the fluidized bed reactor to produce a product stream and a spent catalyst; and transporting the spent catalyst to the catalyst regenerator and regenerating the catalyst in the catalyst regenerator. The product stream comprises olefins having a carbon number of C.sub.2-C.sub.4 and distillate fuel.
PROCESS FOR OBTAINING AROMATICS AND AROMATIC STREAM
The present invention addresses to a process for the production of aromatic compounds from streams containing linear chains with 5 to 18 carbon atoms, of fossil or renewable origin, and application in the field of catalytic cracking aiming at a regenerator operation at much lower temperature, between 480° C. and 620° C., preferably the temperature should be between 500° C. and 600° C. The coked catalyst generated by the cracking of light streams with low potential for delta coke generation can have the combustion effected at a lower temperature. The regeneration temperature must be at least 40° C. and at most 100° C. higher than the reaction temperature, keeping the catalyst circulation high to maintain the energy balance in the reaction section. The minimum regeneration temperature can be ensured by installing an air preheating furnace before entering the regenerator and passing through the air distributor inside the regenerator. The used catalyst must contain zeolite with pores of intermediate size. Such conditions greatly favor the production of aromatics and the octane rating of the produced naphtha.
