Abstract: The present invention concerns a method for baking or calcination of shaped carbon bodies in a furnace and a packing material for use in the same. In accordance with the method, carbon bodies are burned in a furnace chamber, supported or surrounded by a packing material which is formed from a mixture of a material containing carbon and particles of a material containing silicium oxide such as crushed chamotte stone. In accordance with the method, the baking of the carbon bodies will take place at a greater temparature gradient across the packing joint than previously, which results in greater tar combustion and better utilisation of the energy in the degasified components. Furthermore, a packing material is described that contains a component containing carbon and that also contains particles containing silicium oxide in a homogeneous mixture with the component containing carbon. The component containing carbon can be a granulate such as pellets of a mass that comprises dust containing carbon and a binder of tar/pitch. The dust containing carbon in the mass can be made up of butt filter dust which contains sodium and fluorine. The mass can also contain a powder/dust of amaterial containing silicium oxide such as crushed, ground chamotte stone. The present invention results in that materials/substances currently dumped, now can be reused for the baking of carbon bodies within the aluminium industry.

Title: Inverse vertical seismic profiling using a measurement while drilling tool as a seismic source
Inventor: MASAK PETER C
IPC: G01V1/52
Filed: 1997-02-26
Abstract: A reverse VSP system is provided and uses a frequency-controllable modulator of an MWD tool as a downhole seismic source. The modulator has a rotor and stator arranged to provide substantially sinusoidal outputs, and is controlled to provide a "Vibroseis"-type frequency sweep (preferably from 1 Hz to 50 Hz). With the bit of the MWD tool in contact with the bottom of the borehole, the force generated by the frequency-controllable modulator will generate measurable axial compressional (P-) waves. These waves which move through the formation are detected by an array of geophones on the formation surface, and a reference signal is obtained by a kelly-mounted accelerometer or strain gauge. The reference signal and signals obtained by the geophones are processed using known signal processing techniques. The disclosed downhole frequency-controllable seismic source provides many advantages including good resolution due to the ability to output a sinusoidal wave at desired frequencies and the fact that the location of the source signal is well-defined (at the bit), the ability to image formations ahead of the bit, and the ability to conduct reverse VSP processing without adding downhole hardware equipment and without requiring trips out of the well.
