摘要:
The invention relates to a process for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) ebulliated-bed catalytic hydrocracking, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Make-up hydrogen, preferably all make-up hydrogen, is to stage c). Advantageously, the heavier fraction from step (b) is subjected to catalytic cracking. The invention also relates to an installation that can be used for implementing this process.

The invention relates to a process and installation for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) mild hydrocracking in a fixed catalyst bed, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment (including desulfurization) of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Advantageously, the heavy fraction is sent into catalytic cracking. The process preferably operates with make-up hydrogen that is brought to stage c), and very advantageously all of the make-up hydrogen of the process in introduced in stage c).

Aluminum smelter comprising: (i) a series of electrolytic cells, comprising an anode, a cathode and a pot shell equipped with a side wall and a bottom, each cathode including at least one cathode output, (ii) a main electric circuit through which an electrolysis current passes, including an electrical conductor connected to each cathode output of a cell N, and to the anode of a cell N+1, and (iii) a means to stabilize the electrolytic cells. At least one of the cathode outputs of the cathode of N passes through the bottom of the pot shell, and during the operation of N and N+1, the electrolysis current passes, in an upstream-downstream direction only, through each electrical conductor extending from each cathode output of N in the direction of N+1.

An electrolytic cell is suitable for production of aluminium, and includes at least one collector bar made of first metal and at least one complementary bar made of a second metal having an electrical conductivity greater than the first metal and arranged adjacent to one of the side faces of the collector bar so that the external end of the complementary bar is at a specified distance from a specified end face of the block. The second end terminates so as to limit heat losses from said cell. The cell makes it possible to obtain significantly lower voltage drops while avoiding excessive heat losses through the collector bars.

An automated banking a machine such as a teller cash recycler uses a system and method for receiving operating instructions from a remote system in the form of JavaScript object notation (JSON) documents. The system and method uses a computer implemented method for transmitting information between automated banking machines over a communication network. The method includes receiving a message for network communication from a first automated banking machine to a second automated banking machine, formatting the message in a tagless data interchange format independent of the size of the message based on instructions stored on a computer readable medium within the first automated banking machine, and transmitting the formatted message to the second automated banking machine.

A computer implemented method for validating the identity of a controller for an automated banking machine based on displayed indicia. The method includes detecting access to a secure compartment of an automated banking machine, displaying a security indicia visible from the secure compartment, receiving the security indicia at an input device and a first controller accessible from outside of the secure compartment, and validating the identity of the controller based on the received security indicia.

The invention relates to a device (50) and a method for short-circuiting a specified electrolysis in a row of electrolysis cells intended for the production of aluminum. This device includes a bridging member (60) including at least two opposite contact arms and at least one bridging conductor electrically that electrically connects the contact arms. The contact arms are shaped like a wedge. The device further includes a clasping member (70) including a frame and a least two opposite thrust members. The clasping member (70) is fit to embrace the bridging member (60) so that each thrust member bears on each contact arm and so that, upon moving the contact arms with respect to the clasping member, each thrust member urges the corresponding contact arm towards the conductors (201, 202) inserted between the contact arms, so as to create and secure a short-circuit. The invention makes it possible to short-circuit electrolysis cells with increased amperages.
