Title
(EN) METHOD FOR GASIFYING FEEDSTOCK WITH HIGH YIELD PRODUCTION OF BIOCHAR
(FR) PROCÉDÉ DE GAZÉIFICATION D'UNE CHARGE D'ALIMENTATION AVEC UNE PRODUCTION À RENDEMENT ÉLEVÉ DE BIOCHARBON
Abstract
(EN)
A downdraft gasifier and method of gasification with high yield biochar that utilizes a plurality of high throughput, vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. A rotating and vertically adjustable rotating grate is located beneath the reduction zone of the gasifier. In addition, a drying zone is located above the pyrolysis zone so the heat of the gasifier can be used to dry feedstock before it enters the gasifier. By optimizing the grate height and rpm, feedstock retention time in the drying zone, the drying zone temperature and feedstock moisture content, the result is gasification of biomass with a high yield and continuous biochar production.
(FR)
La présente invention concerne un gazéifieur à tirage inversé et un procédé de gazéification avec du biocharbon de haut rendement qui utilise une pluralité de tubes positionnés verticalement, de haut débit pour créer une zone de pyrolyse, une zone d'oxydation placée en dessous de la zone de pyrolyse et une zone de réduction placée en dessous de la zone d'oxydation. Une grille tournante verticalement réglable et rotative est positionnée en dessous de la zone de réduction du gazéifieur. En outre, une zone de séchage est située au-dessus de la zone de pyrolyse de sorte que la chaleur du gazéifieur puisse être utilisée pour sécher la charge avant son entrée dans le gazéifieur. En optimisant la hauteur de grille et la vitesse de rotation, le temps de rétention de charge d'alimentation dans la zone de séchage, la température de la zone de séchage et la teneur en humidité de la charge d'alimentation, la gazéification de la biomasse avec un rendement élevé et une production continue de biocharbon est obtenue.
