PROCESSO E SISTEMA DE PIROLISE COM RECIRCULACAO DE GAS QUENTE

摘要

A continuous process for pyrolysing an organic material in a vertically moving bed reactor (10). A temperature gradient is established through the bed with a maximum temperature of 800-1400 DEG F (427-760 DEG C). From the non-condensible fraction of the gaseous mixture withdrawn at the top (57) of the bed, a first portion (5) is recycled to the energy recovery zone, a second portion (61) to the pyrolysis zone and a third portion (59) to the drying preheating zone.
