    • The invention relates to a process making it possible when a refining catalyst is subject preferably in situ to the conventional activation reaction in the presence of hydrogen (generally at above 100.degree. C.) to carry out, as a result of the in situ presence of hydrogen, the sulphurization at the required stoichiometric or non-stoichiometric level of the active metal or metals in the composition of the catalyst. In the absence of hydrogen, the process consists of incorporating into the porosity of the new or regenerated catalyst at least one sulphurizing agent of general formula:R--S(n)--R'in which n is an integer from 3 to 20 and R represents an organic radical.The invention is characterized in that a critical elementary sulphur quantity is added to the sulphurizing agent. This addition makes it possible to adjust the sulphur content of the presulphurized catalyst to values equal to or higher than stoichiometry, to increase the fixed sulphur quantity after activation under hydrogen and to reduce the exothermy phenomena observed during activation.
    • 本发明涉及一种使得当精炼催化剂优选在氢气存在下(通常在高于100℃)常规活化反应的情况下进行的方法,由于原位存在 氢气,催化剂组合物中所需的化学计量或非化学计量水平的活性金属或金属的硫化。 在不存在氢气的情况下,该方法包括将新的或再生催化剂的孔隙结合入至少一种通式为:RS(n)-R'的硫化剂,其中n为3-20的整数,R表示 有机基团。 本发明的特征在于向硫化剂中加入临界基本硫的量。 这种添加使得可以将预硫化催化剂的硫含量调节至等于或高于化学计量的数值,以在氢下活化后增加固定硫量并减少活化期间观察到的放热现象。

    • The invention concerns a process for the regeneration of a used hydrocarbon treatment catalyst, preferably a reforming catalyst, containing at least one precious metal preferably platinum, optionally at least one additional metal selected from the group formed by metals from groups 7, 8, 9, 10, 13 and 14 of the periodic classification of the elements and copper, optionally and preferably at least one halogen, preferably chlorine, and at least one porous support, preferably alumina, said process comprising at least one of the following two successive steps: at least one step (1) for the combustion of the coke present on said catalyst, carried out in the presence of an oxygen-containing gas, at a temperature in the range of 300.degree. C. to 680.degree. C. for a time in the range 0.3 to 7 hours, at least one step (2) for oxyhalogenation, preferably oxychlorination, carried out in a controlled air atmosphere, at a temperature in the range 350.degree. C. to 550.degree. C., for a time in the range 0.3 to 3 hours and in the presence of a halogenated compound, wherein said process is carried out offsite, and in that a moving bed furnace is used for combustion step (1) and for oxyhalogenation step (2).
