Abstract: A method for improving the thermal characteristics of cement compositions is provided in which fine resilient graphitic carbon particles (“RGC”) are substituted for a portion of the fine aggregate (typically sand) in the cement formulation. For the purposes of the present disclosure, “fine” is intended to describe particulates having a mesh size of less than about 8 mesh, or a particle size of less than about 2.38 mm, or, more preferably when referring to RGC, a mesh size of less than about 16 mesh and a particle size of less than about 1.19 mm. “Resilient” is intended to describe graphitic carbon particles that exhibit a rebound of at least about 20% after compression to 10,000 psi.

Abstract: THE INVENTION PROVIDES A METHOD AND APPARATUS FOR HIGH-TEMPERATURE TREATMENT OF PETROLEUM COKE. IN CARRYING OUT THE METHOD, CALCINED PERTROLEUM COKE, WHICH IS PREFERABLY HOT, IS INTRODUCED INTO A GRAPHITIZING ZONE AND HEATED BY DIRECT ELECTRICAL RESISTANCE. THE COKE IS CONTINUOUSLY AGITATED DURING THE HEATING, AND IS MOVED DOWNWARDLY THROUGH THE GRAPHITIZING ZONE. AFTER PASSING THROUGH THE GRAPHITIZING ZONE, THE COKE IS CONTINUOUSLY TRANSFERRED TO A TEMPERING AND COOLING ZONE, WHERE IT IS CONTINUOUSLY AGITATED. IF IT IS DESIRED TO DESULFURIZE THE COKE, IT IS HEATED TO AT LEAST ABOUT 1700*C., WHILE GRAPHITIZATION REQUIRES A TEMPERATURE OF AT LEAST ABOUT 2200*C.

Abstract: A method and apparatus for high temperature treatment of petroleum coke. In the method, calcined petroleum coke, preferably hot, is introduced into a graphitizing zone and heated by direct electrical resistance. The coke is continuously agitated. If it is desired to desulfurize the coke, it is heated to at least about 1,700*C, while graphitization requires a temperature of at least about 2,200*C. The apparatus comprises means defining a heating zone having petroleum coke input means communicating with an upper portion thereof and at least one electrode in an upper portion thereof. Means defining a tempering and cooling zone are positioned below the heating zone and an agitator, forming an electrode, is positioned at the bottom of the heating zone and mounted for rotation in a horizontal plane. The agitator has at least one aperture which provides communication between the heating zone and the tempering and cooling zone.

Abstract: An improved ground covering and heating means is constructed by formulating graphited concrete containing about 35-85 percent graphite, based on the weight of the dry mix. The concrete is laid in combination with a suitable heating element beneath the upper surface. In the preferred embodiment, the graphited concrete is sandwiched with a lower layer of nongraphited concrete for added strength. In preparing the sandwich, the graphited concrete is preferably poured over the nongraphited concrete while the latter is still in a green state.

Abstract: An assembly for the test chamber of a wellbore fluid testing apparatus for simulating fractures in a wellbore is provided comprising base plate of a first diameter having an aperture therethrough configured to be removably secured within the test chamber. A solid end plate of a second diameter smaller than the first diameter is provided that is removably secured to the base plate. One or more intermediate plates is provided that is located between the base plate and the end plate, each intermediate plate also having an aperture therethrough. At least one shim or spacer is provided to space the intermediate plates from any adjacent intermediate plate and/or to space the end plate from the adjacent intermediate plate. The spacer is configured to be removably secured to the assembly and to permit fluid flow in in the assembly through the aperture in the base plate and the opposed face of the intermediate plate and an adjacent intermediate plate or the base plate.
