  • Patent number: 10400108
    Abstract: The invention described herein relates to a novel process to create carbon black feed stocks derived from coal by utilizing direct coal liquefaction resulting in an economic process for producing carbon black feedstock. Moreover, relative to the current state of the art (use of FCC slurry oil), the invention process will be significantly more profitable when oil prices increase.

  • Patent number: 7938953
    Abstract: An improved process for heavy oil conversion and upgrading and a combined method for heavy oil conversion and vacuum gas-oil treatment are described herein. The method utilizes the creation and recycle of a separate product from the vacuum still, which is thereafter recycled back to the heavy oil conversion reactor. The result is the production of a higher quality medium gas oil product relative to the overall vacuum gas oil product which is acceptable for use in a typical vacuum gas oil treatment process. Additionally, there is a higher diesel yield selectivity from the heavy oil conversion unit.

  • Patent number: 7938952
    Abstract: This invention relates to a novel integrated hydroconversion process for converting heavy atmospheric or vacuum residue feeds and also converting and reducing impurities in the vacuum gas oil liquid product. This is accomplished by utilizing two residue hydroconversion reaction stages, two vapor-liquid separators, and at least two additional distillate ebullated-bed hydrocracking/hydrotreating reaction stages to provide a high conversion rate of the residue feedstocks.

  • Publication number: 20070209965
    Abstract: This invention relates to a process and an installation for treatment of a heavy petroleum feedstock, of which at least 80% by weight has a boiling point of greater than 340° C., whereby the process comprises the following stages: (a) hydroconversion in a boiling-bed reactor operating with a rising flow of liquid and gas, conversion in % by weight of the fraction having a boiling point of greater than 540° C.

  • Publication number: 20050075527
    Abstract: Method for processing hydrocarbons comprising at least two processing chambers and means for separating the liquid and gaseous fractions contained in the polyphasic mixture produced in the first processing chamber, said mixture coming from a zone (700) where a batch of liquid hydrocarbons, a gaseous batch and solid particles come into contact, said method comprising separation of liquid and gaseous phases located in the chamber. Equipment comprising: a) At least a first chamber comprising means inside said chamber for separating gaseous and liquid fractions coming from said zone, b) means for conveying said liquid fraction toward a second chamber, c) a second chamber comprising a second contact zone and means of introducing, into said zone, a gaseous batch and a liquid batch comprising at least a portion of the liquid fraction coming from the first chamber.

  • Publication number: 20040027732
    Abstract: A magnetic read head for use in a magnetic data storage and retrieval system is disclosed. The read head is typically a giant magnetoresistive (GMR) spin valve read sensor with a portion of the GMR spin valve read sensor implanted with ions. The implanted ions improve the GMR sensor's sensitivity to changes in resistance by increasing the resistance of inefficient or ineffective portions of the sensor. The invention is also directed to methods of making GMR read sensors.
