Pyrolytic process and apparatus for producing biomass char and energy

摘要

A pyrolytic conversion assembly for processing biomass including: a rotary kiln including a tube for heating the biomass at pressure having a sealable inlet at a first, higher end for ingress of the biomass, and a sealable outlet at a lower end for egress of charcoal formed from the biomass; and heating elements disposed around the kiln to provide a localized source of heating at a predetermined distance from the sealable inlet for reflux condensation of gas from the biomass.

1. A pyrolytic conversion assembly for processing biomass including:
a rotary kiln including a tube for heating the biomass at pressure having (i) a sealable inlet at a first, higher end for ingress of the biomass, (ii) a sealable outlet at a lower end for egress of charcoal formed from the biomass, and (iii) a decomposition products gas outlet toward the higher end for egress of gaseous smaller order hydrocarbons from the tube; and heating elements disposed around the tube to provide a localised source of heating at a predetermined distance from the sealable inlet for reflux condensation within the tube of heavier hydrocarbons contained in the gas from the biomass, wherein the predetermined distance is sufficient to establish a condensation region within the tube between the location of the heating elements and the first, higher end of the tube such that, in use, heavier hydrocarbons contained in the gas from the biomass condenses within the tube.
