Abstract: U.S. 923,191 & 923,192 ABSTRACT OF THE DISCLOSURE     The ability of a catalyst to operate in a hydrogenolysis mode and effect sulfur release in a reforming process can be effectively suppressed after the freshly prepared catalyst has been regenerated, and reactivated several times, generally about five times or more, by the addition thereto of suf-ficient sulfur to maintain an equilibrium amount of sulfur on the catalyst, preferably a maximum of about 0.01 weight percent sulfur.  If desired, water may be injected to displace excess sulfur from oversulfided catalyst. Preferably, the amount of sulfur added to a fresh catalyst is progressively, and preferably proportionately reduced from one regeneration, reactivation sequence to the next such that, on and after about the fifth regeneration, and reactivation of the catalyst a maximum of about 0.01 weight percent sulfur is added to the catalyst.  The catalyst of the lead reactors of the series is preferably not directly sulfided, but indirectly sulfided by sulfur added to, and released by the tail reactor, or reactors.

Abstract: ABSTRACT     The invention relates to a method of underground mining mineral or preparation of rock cavities, in which method resulting hollow spaces can be refilled entirely or partially with temporarily stabilizing ice.  The hollow space resulting from the mining is prepared in a first step for ice filling in that the geothermal heat content in the walls of the hollow space partially is removed, so that the walls assume a temper-ature below 0°C.  In a second step water is supplied, possibly together with a reinforcing additive, in layers and inter-mittently to the hollow space while the supplied water together with the possibly added reinforcing agent is being cooled and frozen.  In a third step the frozen ice body is maintained by removing the constantly inflowing geothermal energy during a time period deemed necessary for achieving the object.  The cooling preferably is effected by artificially cooled air.          The first step and the third step, however, can be abolished when the climatic conditions are such, that the rock about the hollow space is frozen to below the frezing point.  The cooling air flows in a closed system which is entirely separated from the ventilation air.
