In order to overcome these problems, esterification and transesterification were studied using homogeneous acid catalysis with H2SO4 catalyst and butanol as synthesis alcohol. The butyl esters obtained revealed characteristics in accordance with the standards ASTM D6751 and EN 14214 and similar to those of the gazol of SONABHY. However, the acid number (B.aegytiaca (1.94 mg.KOH / g), L. microcarpa (3.88 mg.KOH / g), P. butyracea (1.96 mg.KOH / g), and S. birrea (3.15 mg.KOH / g)) and viscosity (B. aegytiaca (6.368 mm2 / s), L. microcarpa (7.032 mm2 / s), P. butyracea (6.907 mm2 / s), S...

Die große Mehrheit der Abwässer wird ohne angemessene Behandlung direkt in die Umwelt geleitet, was sich negativ auf die menschliche Gesundheit, die wirtschaftliche Produktivität, die Qualität der Süßwasserressourcen und die Ökosysteme auswirkt. Das vorliegende Dokument ist der Bilanzbericht der Studie über das Pilotnetz der Einleitungsstellen im Jahr 2022. Das Hauptziel der Studie bestand darin, die Auswirkungen von Industrieabwässern auf die Wasserqualität in den Regionen Centre, Plateau Central, Centre-Ouest und Hauts-Bassins zu bewerten. Es wurden drei Arten von Wasser...

The vast majority of wastewater is discharged directly into the environment without adequate treatment, with adverse effects on human health, economic productivity, the quality of environmental freshwater resources and ecosystems. The main objective of the study was to assess the impact of industrial wastewater on water quality in the Centre, Plateau Central, Centre-Ouest and Hauts-Bassins regions. Three types of water were selected: surface water and borehole water located near industrial zones, and wastewater (from wastewater treatment plants and industrial units). The results of these...
