Clean recovery of phenolic compounds, pyro-gasification thermokinetics, and bioenergy potential of spent agro-industrial bio-wastes

Co-combustion characteristics and kinetic analysis of three different wastes of antibiotic fermentation and coal

“…All the heating rates were divided into two stages, but with an increase in the heating rate, the stage moves to the high-temperature zone. 17 This phenomenon will be highlighted in Section 3.2. With an increase in temperature, AFR samples began to undergo gelatinization and coking.…”

“…The first-stage temperature of the AFRs was in the range 180–420 °C, and there was partial mass loss at 100–160 °C, which was due to the loss of moisture and light volatiles. 15,17 The sulfur contents of all samples were very low, indicating that SO x emissions were not of concern during the combustion process. 18 Porous coke was formed due to the release of the volatiles.…”

Chemical Kinetic Modeling of Air–Steam Gasification of Eucalyptus Wood Sawdust for H2-Rich Syngas Production

“…The sample was ground to obtain an average particle size of 100 and 1000 μm. In order to avoid heat- and mass-transfer limitations, small-sized particles (≤1000 μm) are considered for gasification purposes. , The sieved sample is kept in a closed plastic zip-bag to minimize moisture absorption from the surrounding humidity. As per the observation of Geldart for the classification of sand particle fluidization, particles with sizes in the range of 150–500 μm and a density of 1.4 – 4 g/cm 3 (Geldart B) will be considered as the best suitable for the fluidization process .…”

“…Based on the LHV of syngas and biomass feed, the cold gas efficiency (CGE) is defined as follows 5 = + i k j j j j j y { z z z z z CGE LHV LHV energy content of steam gas biomass (29) The carbon conversion efficiency is defined as follows 40 = i k j j j y { z z z X total moles of carbon reacted in the biomass sample total moles of carbon in fresh biomass C (30) On the other hand, the gasification efficiency is based on the total moles of syngas produced. The gasification efficiency (GE) is defined as follows 5 = i k j j j j y { z z z z GE total mass of syngas total biomass feed (31)…”

Residuos agroindustriales como fuente de nutrientes y compuestos fenólicos

“…Lo anterior con el objetivo de crear alternativas que contribuyan a contrarrestar la problemática de pérdida y desperdicio de alimentos, desde su producción en el cultivo hasta la mesa del consumidor. Por otro lado, la Comisión Europea ha promovido la estrategia de implementación de la economía circular [5], bajo la cual, es prioritario convertir los RAI en un recurso para cerrar el ciclo, evitando que terminen en vertederos o sean incinerados con la subsecuente contaminación del medio ambiente [6].…”
