GROUND WOOD PULPS FROM SOME SOFT WOODS

Wood Fuel Properties and Fuel Products from Woods

The fuel properties of wood can be summarized by ultimate and proximate analysis and determination of the high heating value. It is not valid to list these values for species since a species has not been adequately sampled and tested. Enough is known, however, to say that softwoods have a high heating value of about 9,000 Btu per pound; whereas hardwoods have a value of about 8,600 Btu per poun...

The effect of chemical composition on microfibrillar cellulose films from wood pulps: water interactions and physical properties for packaging applications

The interactions with water and the physical properties of microfibrillated celluloses (MFCs) and associated films generated from wood pulps of different yields (containing extractives, lignin, and hemicelluloses) have been investigated. MFCs were produced by combining mechanical refining and a high pressure treatment using a homogenizer. The produced MFCs were characterized by morphology analy...
