Publication number: 20130241094Abstract: The present invention is a preparation method for asphalt-based spherical activated carbon which requires no infusibilization process. Placing coal tar asphalt into a melting device; introducing compressed air of 0.1 MPa-0.5 MPa into the device and stirring until a melting temperature of 280° C.-350° C. is reached; continuing for 2-8 hours until the base material has a softening point of 200° C.-260° C.; after cooling down, pulverizing the base material to obtain asphalt powder. Obtaining 34%-79% by mass of carbon powder, 1%-10% by mass of binder, and 20%-65% by mass of the asphalt powder and then forming spherical particles with a diameter of 0.5 mm-5 mm with the carbon powder, the binder and the asphalt powder at room temperature. Introducing the spherical particles of asphalt directly into an asphalt carbonization furnace for carbonization at a temperature of 600° C.-900° C. under protection of an inert gas to obtain asphalt spherical carbon.Type: ApplicationFiled: February 20, 2012Publication date: September 19, 2013Applicants: SHENZHEN BATIAN ECOTYPIC ENGINEERING CO.,LTD.Inventors: Xiangmin Yu, Yizhou Kong

Patent number: 8455402Abstract: Fluid systems may contain elements to provide changes in bulk fluid density in response to various environmental conditions. One environmental driver to the variable density is pressure; other environmental drivers include, but are not limited to, temperature or changes in chemistry. The variable density of the fluid is beneficial for controlling sub-surface pressures within desirable pore pressure and fracture gradient envelopes. The variability of fluid density permits construction and operation of a wellbore with much longer hole sections than when using conventional single gradient fluids.Type: GrantFiled: November 29, 2012Date of Patent: June 4, 2013Assignee: Baker Hughes IncorporatedInventors: Larry A. Watkins, Roger W. Fincher

Patent number: 8420578Abstract: A low-density ceramic proppant is formed from a light aggregate of a natural mineral and a ceramic binding material in the form of a proppant granule. The light aggregate expands in volume when burnt so that the density of the aggregate is changed. A method of preparing a proppant material is carried out by pre-crushing and pre-mixing of raw components. This is followed by their granulation into proppant granules, drying and screening of the granules to a selected size. The raw components include at least a ceramic binding material and a light aggregate of a natural mineral that, when burnt, expands in volume so that the specific volume of the aggregate is changed. The burning of the light aggregate may be accomplished before or after the aggregate is mixed with the binding material.Type: GrantFiled: April 10, 2008Date of Patent: April 16, 2013Assignee: Schlumberger Technology CorporationInventors: Zinaida Yurievna Usova, Elena Mikhailovna Pershikova
