摘要： Embodiments of the present invention enhance the search experience of a user by looking at the search history of one or more friends to provide search enhancements to the user. The search enhancements may also be based on information within a user's online social network. Search enhancements based on the user's online social network include identifying people within the user's social network that may have information relevant to a query, posts within the social network that are relevant to the query, and feed items. Examples of search enhancements include an annotation or graphic adjacent to a search result indicating the search result has been visited by one of the user's friends. In another aspect, alternative queries from the friends' search history may be suggested to the user during the search session.

摘要： Search results may include both objective results and person results. In one example, a search query is evaluated to determine whether it is the type of query that a user might want to ask to a friend. If the query is of such a type, then the search engine may examine a social graph to determine which friends of the user who entered the query may have information that is relevant to answering the query. If such friends exist, then the friends may be displayed along with objective search results, along with an explanation of each friend's relevance to the query. Clicking on a person in the results may cause a conversation to be initiated with that person, thereby allowing the user who entered the query to ask his or her friend about the subject of the query.

摘要： A selective hydrogenation catalyst system, and a process for its preparation and its use. The catalyst system of the invention comprises a support material, a Pd-containing catalyst component and a Bi-containing cocatalyst component. The catalyst system of the invention is manufactured by impregnating the support material simultaneously or separately with Pd-containing solution, Bi-containing solution or/and one or more other cocatalyst solutions, and then drying and calcining. The activity and selectivity of the catalyst system of the invention, in selective hydrogenation of acetylenic and diolefmic compounds in hydrocarbon feeds, are significantly improved, while the green oil formation and carbon deposit on the catalyst reduced, and the service life increased and production costs decreased.

摘要： The present invention provides a process for selectively hydrogenating C2-C10 greater unsaturated hydrocarbons (acetylenes and diolefins) at the upstream side of a front depropanizer or front deethanizer in an olefin production plant. After passing through a mixed phase hydrogenation reactor to selectively hydrogenate, the olefin plant process stream passes to a front depropanizer or front deethanizer. The process according to the present invention is able to selectively hydrogenate C2-C10 greater unsaturated hydrocarbons (including acetylene), to reduce the number of equipments, the amount of equipment fouling and the energy consumption.

摘要： A selective hydrogenation catalyst for the seletive hydrogenation of unsaturated hydrocarbons, a process for preparing this catalyst and its use. The catalyst of the invention comprises a support, active component Pd, rare earth metals, and auxiliary metal Bi, Ag etc. The catalyst is able to hydrogenate high-unsaturated hydrocarbons such as alkyne with high selectivity at high space velocity while both green oil formation and carbon deposition on the catalyst are very low. It is applicable to an industrial cracking process.
