20110062054 | IMPROVED INTEGRATED PROCESS FOR HYDROGENATION AND CATALYTIC CRACKING OF HYDROCARBON OIL - Disclosed is a combination process for improved hydrotreating and catalytic cracking of hydrocarbon oils, including: contacting residual oil, catalytic cracking cycle oil, and optional distillate oil with a hydrotreating catalyst under hydrotreating conditions in the presence of hydrogen followed by separation of the reaction products to obtain gas, hydrogenated naphtha, hydrogenated diesel oil, and hydrogenated tail oil; contacting the hydrogenated tail oil and optional normal catalytic cracking feedstock oil with a cracking catalyst under catalytic cracking conditions followed by separation of the reaction products to obtain dry gas, hydrogenated naphtha, liquefied petroleum gas, catalytic cracked gasoline, catalytic cracked diesel oil, and catalytic cracking cycle oil; wherein the hydrogenated tail oil and/or normal catalytic cracking feedstock oil are separated into at least two fractions, the light and the heavy fractions or normal catalytic cracking heavy feedstock oil and normal catalytic cracking light feedstock oil, prior to contacting the hydrogenated tail oil and/or normal catalytic cracking feedstock oil with the cracking catalyst. The process according to the present invention is especially suitable for conversion of hydrocarbon oils to produce more products of gasoline or diesel oil. | 03-17-2011 |
20130006028 | CATALYTIC CRACKING APPARATUS AND PROCESS - The present invention discloses catalytic cracking apparatus and process, which are useful for catalytic cracking of heavy oils with a high heavy oil conversion, a high propylene yield and low dry gas and coke yields. | 01-03-2013 |
20130062250 | COMBINED PROCESS OF HYDROTREATING AND CATALYTIC CRACKING OF HYDROCARBON OILS - Disclosed is a combination process for improved hydrotreating and catalytic cracking of hydrocarbon oils, including: contacting residual oil, catalytic cracking cycle oil, and optional distillate oil with a hydrotreating catalyst under hydrotreating conditions in the presence of hydrogen followed by separation of the reaction products to obtain hydrogenated tail oil and other products; contacting the hydrogenated tail oil and optional normal catalytic cracking feedstock oil with a cracking catalyst under catalytic cracking conditions followed by separation of the reaction products; wherein the hydrogenated tail oil and/or normal catalytic cracking feedstock oil are separated into at least two fractions prior to contacting the hydrogenated tail oil and/or normal catalytic cracking feedstock oil with the cracking catalyst. | 03-14-2013 |

20130198811 | Method and Apparatus for Providing a Trust Level to Access a Resource - An approach is provided for providing a trust level to access a resource. A system receives a request at a device, from a first user, to access a resource associated with a second user. The resource is further associated with a predetermined privacy level. The system calculates a trust level between the first user and the second user based, at least in part, on a trust metric. The system then determines whether the trust level meets the predetermined privacy level and grants an access right to the resource based, at least in part, on the determination. | 08-01-2013 |
20140214818 | METHOD AND APPARATUS FOR HYBRID SOCIAL SEARCH MODEL - An approach is provided for determining the intent of a question and determining an appropriate audience to answer the question based on the intent of the question. The approach comprises processing and/or facilitating a processing of a query to cause, at least in part, a determination of one or more topics of the query based, at least in part, on one or more user preferences. The approach also comprises processing and/or facilitating a processing of the query to cause, at least in part, a determination of a classification of the query, The approach further comprises determining an audience comprising one or more candidate audience members for the query based, at least in part, on the classification of the query and the one or more topics of the query. | 07-31-2014 |
20140380420 | METHOD AND APPARATUS FOR EXPANDED CONTENT TAG SHARING - Techniques for expanded content tag sharing include determining that a first user is associated with content provided by a different second user. Data is recorded that indicates the first user is authorized to associate a different third user with the content provided by the second user, without further input by the second user. In some embodiments, the data that indicates the content provided by the second user includes data that indicates a plurality of contents. Some techniques include determining a message received from a first user indicates a portion of content associated with the first user, and a second user. The portion of the content is rendered on an apparatus of the second user. The second user is prompted for associating, with the portion of the content, an item identifier, such as text or another user, for the portion of the content. | 12-25-2014 |
