Co-pyrolysis of sugarcane bagasse with petroleum residue. Part II. Product yields and properties

摘要

The main objective of the present work was to study the pyrolysis under vacuum of sugarcane bagasse combined with petroleum residue (PR), in terms of yields and properties of the products obtained. Important synergetic effects were observed during the co-pyrolysis in a fixed bed reactor leading to an increase in charcoal yield. Maximum charcoal and minimum oil yields were obtained with 15 wt/100 of PR mixed with bagasse. At this concentration, sugarcane bagasse charcoal is almost completely covered with PR-derived pyrolytic carbon. At concentrations higher than 15 wt/100, hydrocarbon vapours interacted less with the bagasse charcoal.
