In this work, the catalytic upgrading of a bio-oil model compound via esterification with ethanol was studied using 12-tungstosilicic acid as the catalyst. The response surface method was used to investigate and optimize the process variables, which include the ethanol to acid molar ratio,...

Sustainable biomass exploitation for combined heat and power (CHP) generation is fundamental to address concerns about … demands exclusively through renewable resources. A layout of a hybrid micro-gas turbine-solarplant fed by biomass from … agriculture products (olive pits) is modelled. It provides the coupling between a gasifier, dedicated to the biomass conversion …

behave as if they maximize their net biomass subject to constraints which express the organisms' risk of being preyed upon … during predation. Like consumers, organisms face a 'budget constraint' requiring their expenditure on prey biomass not to … exceed their revenue from supplying own biomass. Short-run ecosystem equilibria are defined and derived. The net biomass …

The analysis has demonstrated the theoretical energy-production potential of biomass in the areas of fallow and waste … location of decentralised units. Production of biomass for energy purposes requires, first of all, retaining balance between …-production potential of biomass production in the areas of fallow soil and fallow land. This paper presents a model of uncultivated …
