Fast oxidative pyrolysis of eucalyptus wood residues to replace fossil oil in pulp industry

This study evaluates the potential of oxidative fast pyrolysis (OFP) eucalyptus wood residues (EWR) for producing bio-oil to replace fossil fuels in lime kilns pulp industry. OFP is an alternative inert-atmosphere where separate heat addition stage not required. was studied by characterizing fuel using proximate and elemental chemical analyses, thermogravimetric analysis heating value. Then, experiments a pilot-scale autothermal fluidized reactor were done with EWR. Pyrolysis products gases, bio-char (heavy light). The gases burnt, energy used fluidization air. Heavy yield 30% 21.4 MJ kg?1 lower value indicate good applications. results model evaluate industrial-scale cases. Integration mill recovery boiler steam cycle allows easy considerable waste from process itself, as well combustion solid gaseous residues. Economic indicates profitability fine EWRs mill. A higher net present value, but longer payback period, obtained larger plant purchased feedstock. Stand-alone production found unprofitable.
