It is a light, volatile, colorless and flammable liquid with a distinctive alcoholic odor similar to that of ethanol (potable alcohol), but is more acutely toxic than the latter. [17] Methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood.
Sawdust brandy (from the German Holzbranntwein) is a neutral spirit produced through the distillation of wood products.. To produce sawdust brandy, the wood is cooked with a diluted sulfuric acid, which causes the cellulose to be broken down via acid hydrolysis into dextrose and other simple sugars, while the lignin remains.
The bioconversion of biomass to mixed alcohol fuels can be accomplished using the MixAlco process. Through bioconversion of biomass to a mixed alcohol fuel , more energy from the biomass will end up as liquid fuels than in converting biomass to ethanol by yeast fermentation.
Furfurylated wood, holding the Scandinavian ecological label Swan, is today traded as an environmentally friendly product since both the wood and furfuryl alcohol are produced from renewable raw materials. [14] In recent years, attempts to make furfurylated wood as a fire resistant material, have been made. [15] [16]
Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit. It can be produced from grasses, wood, algae, or other plants. It is generally discussed for use as a biofuel.
Storing, shipping, and fermenting alcohol became the main uses for wooden barrels. [18] In the early days, Guinness employed its own team of up to 300 highly-paid coopers in the brewery, making barrels which would be shipped around the world, and wooden casks were used by the brewery for nearly two centuries.
Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The method may involve pyrolysis or thermolysis, or it may not (for instance, a simple mixture of ice and glass could be separated without breaking any chemical bonds, but organic matter contains a greater diversity of molecules, some of which are likely to break).
The black liquor contains more than half of the energy content of the wood fed into the digester of a kraft pulp mill. [11] It is normally concentrated to 65 - 80% by multi-effect evaporators and burned in a recovery boiler to produce energy and recover the cooking chemicals. The viscosity increases as the concentration goes up.
