“…Previous studies showed that the temperature played significant role in biomass upgrading and in general the temperature range of 200-300°C was suggested to produce solid fuel biochar from biomass [10,12,15]. In the present study, it was shown that woody biomass PW should be pyrolyzed at higher temperature than agricultural waste CF to obtain better combustion efficiency.…”

“…Compared to liquid and gaseous products, only a few studies have been carried out with the aim of producing solid fuel biochars from waste biomass, and most of these studies focused on the improved physicochemical properties of woody biomass [9][10][11][12][13][14][15][16]. In contrast, limited studies are available for the biochars derived from most abundant agricultural wastes and there is a lack of information about the comparison of fuel qualities of the biochars from woody biomass and agricultural residue [10,[13][14][15][16].…”

“…These compounds may come from varnishes and resins such as urea formaldehyde and melamine formaldehyde, common in wooden waste panels (DEBAL et al, 2014;GIRODS et al, 2008). The release of these volatiles during torrefaction is intrinsic to the process, according to Gucho et al (2015), Lee et al (2012) and as reported in van der Stelt et al (2011): they may contain about 10% of the energy of the biomass. Regarding ash content, torrefaction did not show a tendency of increasing or decreasing.…”

“…A mild heat treatment technique known as torrefaction is proposed as a pre-treatment process for upgrading of oil palm biomass, both as solid fuel and as an initiation step for further thermochemical processing. Studies agreed that torrefaction has the potential to increase heating value of torrefied woody biomasses, thus improving their combustion efficiency [5,6]. Improved hydrophobic characteristic of the torrefied biomass allows easier handling and uniformity of the biomass samples [7].…”
