The Importance of Biomass

Energy Sources, 2004
Various agricultural residues such as grain dust, wheat straw and hazelnut shell are available in Turkey as the sources of biomass energy. Among the biomass energy sources, fuelwood seems to be one of the most interesting because its share of the total energy production of Turkey is high at 21% and the techniques for converting it to useful energy are ...

Mesurer l’épaisseur des résidus à la surface d’un sol pour estimer leur biomasse

Cahiers Agricultures, 2019
Aujourd’hui, les résidus de culture ne sont plus considérés comme des déchets : leur contribution aux équilibres agronomiques et environnementaux des systèmes de culture est reconnue. Dans ce contexte, connaître leur quantité à la surface d’un sol, après

Energy from Biomass for Conversion of Biomass

Latvian Journal of Physics and Technical Sciences, 2009
Along with estimates of minimum energy required by steam explosion pretreatment of biomass some general problems concerning biomass conversion into chemicals, materials, and fuels are discussed. The energy necessary for processing biomass by steam explosion auto-hydrolysis is compared with the heat content of wood and calculated in terms of the amount ...

Räumliche Entwicklung von Koks in ZSM‐5‐Katalysatoren während der Umwandlung von Methanol in Kohlenwasserstoffe, aufgezeigt durch in‐situ‐Röntgen‐Photoelektronenspektroskopie

Angewandte Chemie, EarlyView.
Oberfläche enthüllt: Verkokung ist die zentrale Ursache für die Deaktivierung von Zeolithkatalysatoren. Mithilfe von In‐situ‐XPS in Verbindung mit ergänzenden Methoden identifizieren wir Unterschiede in der Bildungskinetik und Zusammensetzung von Oberflächenkoks auf industriell relevanten ZSM‐5‐Katalysatoren während der MTH‐Umwandlung und zeigen damit ...

Does the Application Flow Rate of Nutrient Solutions Prepared in Brackish Water Affect Coriander Production?

Irrigation and Drainage, EarlyView.
ABSTRACT Flow rates for applying nutrient solutions in hydroponic systems are empirically known, yet uncertainties remain regarding whether brackish water affects the optimal flow rate and, consequently, biomass production and allocation. This study evaluated whether variations in application flow rate affect coriander biomass when brackish water is ...
