Différents phosphates ont été préparés et testés pour la déshydratation de l'acide lactique en phase gaz. La sélectivité en acide acrylique dépend fortement de la température de réaction mais peu du temps de contact. A 380°C, des valeurs de sélectivité allant de 19 à 50% ont été mesurées pour des phosphates alcalino-terreux qui sont stables sur au moins 24 h. Des mesures d'acido-basicité ont montré que ces phosphates contiennent une forte proportion de sites de même force faible. De plus, une corrélation entre la sélectivité en acide acrylique et le ratio molaire acide/base a été établie : ell

Abstract:

During the production of steel, an oxide scale is formed on the surface and to achieve anadequate quality of the surface the scale needs to be removed. Acid pickling is a surfacetreatment where the oxide scale is removed by acid. Over time the amount of dissolved metals in the acid solution increases leading to a decrease in the pickling efficiency, hence the acid solution needs to be renewed. The renewing can be performed by an operation process called acid retardation. In this process, the spent pickling solution passes through a column packed with an ion exchange material, resin.

Abstract:

Background: Fatty acids (FA) have a role on energy storage and membrane formation. FA consists of an aliphatic chain with varying number of carbon and a carboxylic functional group. Perfluorooctanoic acid (PFOA) exhibits a similar structure to that of the FA. Given their structural resemblance, we hypothesized that alterations in FA metabolism could arise from competition with PFOA for endogenous FA binding sites in transport and with FA binding proteins. Objectives: Explore associations of serum concentrations of perfluorooctanoic acid (PFOA) with serum concentrations of linoleic (LA), eicosa

Abstract New methods are being sought for the production of chemicals, fuels and energy from renewable biomass. Lignocellulosic biomass consists mainly of cellulose, hemicellulose and lignin. Cellulose and hemicellulose can be converted to their building blocks, i.e. sugars, via hydrolysis. This thesis is focused on glucose production from cellulose by dilute acid hydrolysis. Acid hydrolysis has the drawback of limited glucose yields, but it has the potential to become a short-term solution for biochemical production. During acid hydrolysis, the cellulose chain is split into glucose, which und

Abstract:

Acid fracturing is one of the preferred methods to stimulate wells in carbonate reservoirs. It consists of injecting an acid solution at high enough pressure to break down the formation and to propagate a two-wing crack away from the wellbore. The acid reacts with the carbonate formation and this causes the etching of the fracture surfaces. After the treatment, the created etched surfaces do not close perfectly and that leaves behind a highly conductive path for the hydrocarbons to be produced.
