摘要:
This invention relates to a catalyst for hydrotreatment of hydrocarbons comprising one or more of metals selected from the group consisting of transition metals and metals of group IIb of the periodic table supported on sepiolite. More particularly it relates to a catalyst effective in the selective demetallization treatment of hydrocarbons.

摘要:
A system and method enables the reception of signals on a moving Personal Station (PS) within an Integrated Voice and Data (IVD) system which integrates sound and data, and comprises an available PBX and LAN. A first Cell Station (CS) registers the LAN identifier of a first PS that is positioned within its own radio cell, and assigns a PBX telephone number to the first PS. Subsequently, calling information which includes a LAN identifier for a second PS and the PBX telephone number assigned to the first PS is broadcast via a LAN. Thereafter, a second CS which registers the LAN identifier of the second PS receives the calling information via a LAN and transfers the information of the second PS, or mobile station, via radio link. The second PS then dials the PBX telephone number included in the calling information. Thus, the link between the first PS and the second PS is connected when the first PS receives the call.
