Acid hydrolysis of olive tree biomass

摘要: Abstract Olive tree cultivation generates a great amount of biomass residues which have no industrial application. Pruning are usually grindered or burnt on fields, causing economical costs and environmental concerns. An alternative issue for these renewable sugar-containing feedstocks may be the conversion into fuel ethanol by hydrolysis fermentation. As first step in bioconversion process, acid olive pruning is studied mathematical model predicting both fiber content sugar release as function operation variables proposed. Sulphuric concentration range 0–32% (w/w), process temperature between 60 90 °C time from 0 to 240 min were used conditions. The was modelled first-order reaction kinetics. apparent kinetic constant relating shows potential dependence; other hand, an Arrhenius-type equation has enabled evaluation activation energy values 26.4 25.9 kJ/mol generation, respectively.
