  • Patent number: 9901908
    Abstract: An improved catalyst for hydrodemetallization of heavy crude oils and residua is disclosed. The catalyst is adopted for fixed bed hydroprocessing units. The invention is characterized for having a large pore diameter catalyst principally for hydrodemetallization of heavy oil and residue in a first reactor of a multi-reactor process. The catalyst has high demetallizing activity and high metal deposition capacity which results in good stability with time on stream (TOS). The hydrorefining catalyst is obtained by kneading a porous starting powder principally composed of gamma-alumina and having a pore capacity of 0.3-0.6 ml/g or larger and a mean pore diameter of 10 to 26 nm, extrudating and calcining, and after that supported with active metals component of elements belonging to groups VIIIB and VIB of the periodic table.

  • Patent number: 9754235
    Abstract: Various embodiments of a system and method for authoritative item identification based on facility operations are described. Embodiments may include an authoritative item identification component configured to, for each particular item of multiple items in inventory of a materials handling facility, determine multiple identifiers for the particular item, where one or more of the multiple identifiers are electronically obtained from a unit of the particular item during operations of the materials handling facility. The authoritative item identification component may, for each of the multiple identifiers, determine a quantity of instances in which that identifier was electronically obtained from a given unit of the particular item. The authoritative item identification component may, based on a statistical analysis of the quantities, determine one of the multiple identifiers as being an authoritative identifier for the particular item.

  • Patent number: 9747440
    Abstract: Methods, systems and devices for generating data models in a client-cloud communication system may include applying machine learning techniques to generate a first family of classifier models that describe a cloud corpus of behavior vectors. Such vectors may be analyzed to identify factors in the first family of classifier models that have the highest probability of enabling a mobile device to better determine whether a mobile device behavior is malicious or benign. Based on this analysis, a second family of classifier models may be generated that identify significantly fewer factors and data points as being relevant for enabling the mobile device to better determine whether the mobile device behavior is malicious or benign based on the determined factors. A mobile device classifier module based on the second family of classifier models may be generated and made available for download by mobile devices, including devices contributing behavior vectors.

  • Patent number: 9387466
    Abstract: This invention reveals a method for synthesizing a hydrotreating catalyst wherein the support is prepared by mixing of peptized alumina with an amorphous silica or crystalline aluminum silicate as one component of the catalyst. The catalyst comprises a group VI metal and/or a group VIII metal of the periodic table. The catalyst exhibits improved hydrocracking, hydrodesulfurization and hydrodemetallization activities and has a relatively stable life with time on stream. Thus, the invention concerns a method for developing a catalyst for hydroprocessing of heavy hydrocarbon feedstocks which is characterized by two steps: the first step consists of the optimization of a catalyst formulation with respect to the textural properties, number of acid sites, active metal incorporation. The second step consists of the evaluation with real feedstock and catalyst stability with time-on-stream.
