Fast pyrolysis, with high heating rates and short retention time, was studied extensively in past decades due to high liquid yields. Although many fast pyrolysis processes have been developed and tested, few were reported to be successful on commercial scale due to problems including poor tar quality and system plugging. It is, therefore, important to exam the reactivity of the fast pyrolysis tars...
Fast pyrolysis of biomass has attracted increasing attention worldwide to produce bio-tars that can be upgraded into liquid fuels and chemicals. However, the bio-tars are usually poor in quality and stability and are difficult to be upgraded. To better understand the nature of the bio-tars, this work reveals radical concentration of tars derived from pyrolysis of two kinds of biomass. The tars were...
Bio-oil from the pyrolysis of biomass can be upgraded into high quality liquid biofuels or utilised as a feedstock to boilers and gasifiers. The coke formation is a particularly serious problem for the upgrading of bio-oil as well as the direct utilisation of bio-oil. The effects of bio-oil chemical composition on the coke formation are keys to the understanding of the mechanism of coke formation...
The effect of sulfuric acid concentration on the yield and composition of bio-oils obtained from the auger and fluidized bed pyrolysis of Douglas Fir at 500°C have been investigated as a mean to enhance the production of fermentable sugars. The concentration of sulfuric acid in the feedstock was varied between 0 and 0.6mass%. The overall yield of pyrolysis products (gas, bio-oil and char) was comparable...
Mallee eucalypt crops from the low-rainfall dryland agricultural regions of southern Australia may become a major source of woody biomass for production of liquid biofuels through pyrolysis and biorefinery. Pyrolysis studies have commonly focused on the woody fraction and relatively little is known about the pyrolysis behaviour of leaves that make up a substantial portion of the overall plant biomass...
Pyrolysis bio-oil contains abundant O-containing structures. Carbonyls are particularly important not only because they are abundant and exist in many forms (e.g. as acids, esters, ketones and aldehydes) but also because they are reactive and are a key consideration of bio-oil upgrading. This study aims to investigate the distribution of carbonyl groups in a variety of bio-oil samples prepared from...
