标 题 :Process for the synthesis of ziegler-type catalytic solids or solid constituents of the same
发明人：BRUN CLAUDE
权利人:ATOCHEM ELF SA
摘要:A process is provided for the synthesis of a solid Ziegler catalyst or of a transition metal solid constituent thereof, which entails preparing the solid catalyst or constituent thereof as a suspension in an inert liquid medium by contacting precursors or ingredients of the catalyst or of the constituent in the inert liquid medium in one or more steps, and drying the suspension, and collecting the catalyst or constituent thereof; and wherein the process is conducted in a single multi-function reactor having a longitudinal axis and which can pivot around an axis which intersects perpendicularly with this axis.

摘要:The disclosure herein discloses a general method for the synthesis of FeCoNiCu-based high-entropy alloy and their application for electrocatalytic water splitting, belonging to the technical field of preparation of composite materials. The catalytic material for electrolysis of water includes a reaction active material and a support. The reaction active material is FeCoNiCu-based high-entropy alloy nanoparticles such as FeCoNiCuSn, FeCoNiCuMn, FeCoNiCuV or the like. The support is a carbon nanofiber material prepared by electrospinning. The catalytic material for electrolysis of water prepared in the disclosure herein has a high specific surface area, which facilitates diffusion of the electrolyte and desorption of gas. By using the catalytic material for electrolysis of water, hydrogen and oxygen can be produced under alkaline conditions, and the hydrogen production rate under high voltage is much higher than that of a 20% Pt/C electrode. Meanwhile, the carbon nanofibers can effectively protect the high-entropy alloy nanoparticles from erosion of the electrolyte, and endow the catalytic material with good stability.

标 题 :Magnetic drive system for reactor used in the synthesis of Ziegler-type catalytic solids or solid constituents of the same
发明人：BRUN CLAUDE
权利人:ATOCHEM ELF SA
摘要:A magnetic drive system in a reactor generates rotational and translational motion of the agitator. The magnetic drive system includes a tubular shaft having one end attached to the agitator, and another end. A magnetic annular weight is fitted to the another end. A guide column has an end supported by the reactor body and a free end, the guide column further having a cylindrical bore in which an intermediate part of the tubular shaft slides in a fluid tight manner. A cylindrical guide cap is fluid tightly mounted to the free end of the guide column, the guide cap covering the magnetic annular weight and incorporating a cylindrical guide shaft integral with a bottom of the cap, the tubular shaft sliding coaxially and fluid tightly on the guide shaft. A drive rotor covers the guide cap and has another annular magnetic weight enclosing the guide cap and positioned with respect to the annular weight fitted to the tubular shaft such that a rotational or translational movement of the drive rotor generates a corresponding movement of a tubular shaft and the agitator. A motor is connected to the drive rotor for driving the rotor about an axis coaxial with the axis of the reactor body.

摘要:The invention relates to a multi-stage process for the continuous, phosgene-free preparation of (cyclo)aliphatic diisocyanates that comprises the conversion of (cyclo)aliphatic diamines into the corresponding (cyclo)alkylene biscarbamates and the thermal cleaving of the latter into the (cyclo)alkylene diisocyanates and alcohol. The urea used in accordance with the invention and also the urea employed for the preparation of urea equivalents (e.g. alkyl carbonates, alkyl carbamates) as a possible precursor for the synthesis of the (cyclo)aliphatic biscarbamates is unconditioned.
