摘要： The invention concerns a process for the elimination of mercury from hydrocarbons by passage of the feedstock with hydrogen over a catalyst then bringing the product obtained into contact with a mercury retention bed, the catalyst comprising at least one element selected from the group constituted by iron, nickel, cobalt, molybdenum, tungsten, palladium, wherein at least 5% is in the sulphide state. Any arsenic present in the feedstock is also eliminated.In accordance with the invention, the catalyst is simultaneously presulphurated and reduced.The invention results in a considerable reduction in operation period and high retention efficiency at temperatures between 120.degree. C. and 250.degree. C. and in the presence of 0-1000 mg of sulphur/kg of feed.

摘要： The invention relates to a personal weapon, intended for semi-automatic and automatic firing of caseless ammunitions, provided with an electronic fire controller with biometric identification of the person firing. The weapon has a sealing device for the chamber based on using segments or corollas with variation of bore size mechanically or with gas pressure. A delay in opening the barrel/breech unit may be introduced using spigots driven by propellant gases. A device for sequencing compartments in tandem of the magazine uses the volume reduction of ammunition to double the power of the firearm. A removable locker permits the integral locking of breech unit, trigger, magazine and dismantling bolt for an absolute weapon safety. A telescopic extension device for the barrel increases the power of the ammunition and a gas bleed in the chamber permits the stabilisation of the firing.
