    摘要: A catalyst for the steam dealkylation of aromatic hydrocarbons, comprising a carrier and 3 metals, is regenerated in the reaction zone containing the catalyst bed, after disconnection of said zone from the producing unit, by proceeding to the successive steps of: scavenging said zone with hydrogen and then with an inert gas, progressively replacing said inert gas by a gas containing molecular oxygen, burning the catalyst at a temperature lower than 650.degree. C. so as to calcine the carbon deposits of the catalyst, passing through the catalyst bed an air stream containing halogen to increase the halogen content of the catalyst, calcining by means of an air stream at a temperature of 300.degree.-600.degree. C. and purging with an inert gas before reconnecting said reaction zone to the producing unit.

    摘要: The invention relates to an ergonomic body for a personal firearm comprising two horizontally-adjacent parallel barrels. Said body gives a particularly ergonomic grip thanks to the use of a central stock (1) under which three handles are arranged, a central handle (2) and a handle at each end. The front handle (3) has a triple role in shooting ergonomics, as common cocking lever for both barrels and integrated gun rest. The central handle (2) provides a rapid selection of the barrel thanks to a selector (16) placed beneath the trigger guard and an increase in the lazed shooting range by means of an ergonomic selector (64) operated by the shooter's thumb. The rear handle (4) combines the housing of two magazines (22 & 23) with the function as a butt. A telescopic bayonet (13) also provides a flame-catching function in the employed position. The body also comprises a recoil shock absorber on firing ammunition with high specific power, which functions using the propellant gases.

    摘要: A process for hydrotreating a hydrocarbon feed, comprising subjecting said feed to hydrotreating conditions in the presence of a catalyst comprising an essentially alumina-based extruded support, essentially constituted by a plurality of juxtaposed agglomerates, optionally at least one catalytic metal or a compound of a catalytic metal from group VIB (group 6 of the new periodic table notation) and/or optionally, at least one catalytic metal or a compound of a catalytic metal from group VIII (group 8, 9 and 10 of the new periodic table notation), in which the sum S of the group VIB and VIII metals, expressed as the oxides, is 0% to 50% by weight, and wherein each of these agglomerates is partly in the form of packs of flakes and partly in the form of needles, said needles being uniformly dispersed both about the packs of flakes and between the flakes, in which the alumina agglomerates are obtained by forming a starting alumina originating from rapid dehydration of hydrargillite and in which the amount of alumina from boehmite decomposition is 5% to 70% by weight.
