Resumo
An innovative Biomass Refinery concept is presented. The Refinery uses any kind of biomass (wood, agricultural residues and organic matter of municipal solid waste), and produces chemicals, clean fuel and materials. Biomass Refinery is a null pollution thermochemical sequential cracking of any biomass, composed of six necessary and sufficient units: 1st) Diluted acidic prehydrolysis where biomass is cracked to a sugar solution called prehydrolysate, and a cellulignin powder with 20 MJ/kg of heating power and low ash content; 2nd) Furfural reactor and its distillery converting prehydrolysate to furfural; 3rd) Affluent treatment station generating sludge and recycled water to the Biomass Refinery without any effluent discharge to the environment; 4th) Low temperature conversion of any sludge, tires and plastics to oil (tar, diesel and limonene depending on the material processed), and coal; 5th) Combined cycle thermoelectric plant composed of a gas turbine burning oil and cellulignin powder in an external combustor and a recovery boiler/steam turbine burning coal from the low temperature conversion as a supplementary fuel; 6th) Ceramic vitrification of nanometric ash produced in the thermoelectric aiming to partially replace feldspar in the ceramic industry. The integral utilisation of the biomass allows the competition with fossil fuels and chemicals. Prehydrolysis reactor is mobile and processes raw biomasses in parking lots annex to their production. The cost of the cellulignin ranges from US$ 0.50 to US$ 1.50/MBTU, depending on the type of the biomass, considerable lower than the costs of charcoal (US$ 3.20/ MBTU), metallurgical coal (US$ 1.97/MBTU) and coke (US$ 3.44/MBTU). The paper will discuss the applications of the cellulignin as a coal injected powder and a self-reducing agent for agglomerates.
