摘要:
The invention relates to a method for separating xylenes by means of a simulated mobile bed using an agglomerated zeolitic adsorbent solid, preferably based on faujasite zeolite with a Si/Al ratio of between 1 and 6, said solid being used in the form of particles having a diameter of between 150 μm et 500 μm.
摘要:
The present invention relates to aqueous formulations in the form of oil-in-water emulsions including at least one fatty primary amine, intended to be applied to powder or granulated mineral products in order to prevent said products from caking and taking in water. The present invention also relates to the method for applying the emulsions to the aforementioned mineral products, said method being performed at ambient temperature.
摘要:
The present invention relates to a bituminous composition comprising at least one bitumen and at least one polyolefin capable of forming a supramolecular assembly comprising one or more associative group(s).The present invention also relates to the use of such bituminous composition for the preparation of asphalt mixtures useful for the coating of rolling surfaces, for the preparation of water-proofing coatings, and for the preparation of adhesive formulations.
摘要:
The present invention relates to spherical agglomerates based on zeolite(s) and clay(s), having controlled size and morphology, in particular a size of less than or equal to 600 µm, very good sphericity, and a high content of zeolitic material, and also to the process for the production thereof. These agglomerates are particularly suitable for uses in gas-phase and/or liquid-phase adsorption processes.
摘要:
This invention relates to the modification of bitumen by polymeric materials used particularly for the preparation of asphalt mixtures with enhanced mechanical properties, wherein the polymeric materials are selected from additives capable of forming a supramolecular assembly. The modified bitumen may be used for the fabrication of asphalts mixtures with mineral aggregates used in construction or maintenance of sidewalks, roads, highways, parking lots or airport runaways and service roads and any other rolling surfaces.
