Title: Procedure to prepare a supported trimetallic catalyst for production of ultra low sulfur diesel and its application
Inventor: BLANCA LUCIA MEDELLÍN RIVERA
IPC: F01N3/035
Filed: 2018-10-12
Abstract: According to this invention, a Ni-Mo-W trimetallic catalyst supported on porous alumina is obtained that shows very high activity for hydrotreating (HDT) of gasoils, particularly deep hydrodesulfurization (HDS) and hydrodesnitrogenation (HDN) of straight run gasoil in conditions of moderate pressure. When the catalyst is applied to HDT of diesel, the NiMoW catalyst exhibits high catalytic activity. The content of sulfur and nitrogen in the resulting diesel can be reduced from 13,200 to 10 ppm and nitrogen from 360 ppm to less than 1 ppm, under moderate pressure, temperature and space-velocity (LHSV) similar to those of an industrial unit. The catalytic composition, of trimetallic type, is prepared from an alumina support of high surface area to which a solution containing a metal precursor of an element of group VIB is added, followed by other solution that contains one of the precursors of the active metallic phase, a solution containing another of the precursors of the active metallic phase from group VIB, a metal promoter of group VIII and an additive promoter of acidity from group VB, and finally another solution containing a metal of group VIB, a metal of Group VIII and an organic compound, the used route promotes the preferential formation of well dispersed structures of the used metals on the support of porous alumina, less refractory to sulfidation, with high stacking and short lengths of metal sulfides formed in the resulting hydrodesulfurization catalyst. In the formulation, at least a percentage, but not all the Mo is replaced by W, in a Mo/W molar ratio of 0.6 to 2.0.

Patent NL-8103835-A (NL)
IPC: H02K29/08
Filed: 1981-08-17
Abstract: A motor is self-starting using only one magneto-sensitive element because the motor is of a two-phase type and is provided with a detection device which detects towards which of the two phases the rotor is mainly directed. A presetting circuit compares the detected rotor position with the state of an energizing circuit in order to set this circuit so that the energizing circuit energizes the stator phases for said specific rotor position in such a way that starting of the motor is guaranteed, although initially with an undefined direction of rotation. By presetting the commutating direction of the energizing circuit the rotor subsequently locks the field which rotates in the correct direction if it has started in the incorrect direction.

Title: Device for supplying liquid manure
IPC: A01C23/00
Filed: 1991-09-24
Abstract: The present invention relates to a device for supplying liquid manure to below the surface of the ground, comprising a passage which is provided with an outlet opening, wherein a valve is arranged in the passage, which valve is designed in such a manner that it is only possible for liquid manure to flow out when the outlet opening is located beneath the surface of the ground. This prevents manure from making a mess, leading to environmental problems. Preferably, the valve is actuated by a body which rests on the surface of the ground and opens the valve when the outlet opening is located beneath the surface of the ground and closes the valve when the outlet opening is located above the surface of the ground.
Patent NL-9101796-A (NL)
IPC: H04B7/204
Filed: 1991-10-25
Abstract: Known methods for authenticating communication participants add a code word to a command signal, which code word is a crytographic function of the command signal and a key value which in its turn is a function of a master key value and a change code word. The master key value has a permanently fixed value, in contrast to the change code word which serves to change the key value. The method according to the invention makes use of a key value which is a function of at least one previous key value, the master key value with the permanently fixed value, which, once it has been discovered or leaked, substantially weakens the encryption, no longer being required. <IMAGE>
