The production of upgraded bio-oils by an integrated process using a mixture of calcined limestone and sand as a heat carrier with catalytic properties was experimentally studied at pilot scale. The integrated process consisted of two main steps: biomass catalytic pyrolysis in an Auger reactor for bio-oil production and char combustion in a fluidised-bed combustor for heat carrier heating and regeneration...
Production of upgraded bio-oils by catalytic pyrolysis of wood biomass was studied in an auger reactor using low cost materials as catalysts. These materials included several clay minerals (sepiolite, bentonite and attapulgite) and an industrial waste from alumina production, known as red mud. The influence of temperature (400–500°C) and the effect of catalyst to biomass ratio (3:1–1:6, in weight)...
From the many variables influencing the emissions at the new power stations provided with fluidised bed combustors, the airflow influence on PAH emissions at coal AFBC has been studied in this paper. The interval from 700 to 1100l/h with gradual increases of 100l/h is studied in detail in relation to polycyclic hydrocarbons emissions. Similar conditions to those used in coal AFBC at the power stations...
