Abstract
In this study, the corn cob was torrefied at five different temperatures (200, 225, 250, 275 and 300°C) for four different residence times (15, 30, 45 and 60 min). The physical and chemical propert...

Pakistan has 185 billion tons of Thar lignite coal
The present study focuses on the investigation of the physicochemical composition of the solid torrefied biomass along with Thar coal
The presented data indicate that an increase in the torrefaction temperatures and residence times leads to a decrease in the volatile matter content and an increase in fixed carbon content (Ohliger et al, 2013; Sadaka and Negi, 2009; Wannapeera et al, 2011)
Summary
Pakistan has 185 billion tons of Thar lignite coal. Pakistan is an agricultural country rich in agricultural residues. The annual production of corn cob is 600 million metric tons. Biomass absorbs moisture which leads to degradation upon long storage and results in a low heating value fuel. This characteristic, coupled with low energy density, makes it more expensive for transportation (McKendry, 2002). Biomass is fibrous in nature and tenacious to grind to desired particle sizes which require high energy input. The biomass requires drying, as moisture is an important factor during milling (Arias et al, 2008)
