Title: Diacritic cracking of hydrocarbon feeds for  selective production of ethylene and synthesis gas
Inventor: GUTH EUGENE D
IPC: C10G9/38
Filed: 1979-06-15
Granted: 1981-12-01
Abstract: ABSTRACT The present invention relates to improvements in a com-mercial process for non-tubular cracking of heavy hydrocarbon feeds for the purposes of producing ethylene and other valuable olefin products as well as chemical grade synthesis gas.  The prior art cracking processes fail to present a practical and economical process for producing high yields of ethylene by the diacritic cracking of heavy hydrocarbon feed stocks at elevated Pressures in such a way that the reacotr and subsequent heat exchange equipment will not be adversely affected by severy coking.  According to the present invention, a fuel is combusted with oxygen in the first section of the multi zone reactor.  The high temperature products of combustion of the first zone pass into a second section of the multi-zone reactor where the heavy hydrocarbon feed is atomized and injected in such a manner that the contact of the hydrocarbon feed stocks and the combustion gases cause higher selective diacritic cracking of the hydrocarbon feed into various by-products, including a high yield of ethylene.  The reaction products of the second zone then pass into a third section of the reactor in which the products are quickly quenched to reduce the overall temperature and prevent further cracking.  In each stage of the multi-zone reactor the present process seeks to prevent the build-up of coke deposits on the walls of the reactor.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a method for the calibration or checking of dynamometers.  In accordance with the invention, a force is applied to the dynamometer subjected to calibration or checking through a master dynamometer.  The force is pro-gressively changed in magnitude.  In addition, the force applied to the dynamometer subjected to calibration is retained after each application of force.  Simultaneously, the master dyna-mometer is relieved of the force applied.  An apparatus for this calibration includes a bedplate, a first frame rigidly attached to the bedplate, a second frame installed on the first frame with provision for free displacement, and a master dyna-mometer interposed between the two frames.  Interposed between the two frames is also a dynamometer subjected to calibration or checking.  A force is applied to the dynamometer subjected to calibration or checking, and a calibrated force is applied to the dynamometer through the master dynamometer.  A second force is applied only to the dynamometer subjected to cali-bration or checking thus assuring that the master dynamometer is relieved of the force applied.

The knife has a handle, a circular housing secured to one end of the handle, and a rotatably power driven ring-like blade in part circumferentially contained by the housing.  An arcuate wear pad or plate overlies a portion of the inside surface of the blade adjacent the handle limiting movement of the blade away from the blade housing near the handle and against the surrounding housing opposite the handle during use, distributing wear that otherwise occurs between the interior of the surrounding housing and the outside of the blade, and transferring some of the wear to the exterior of the wear plate and the inside of the blade. The ends of the wear plate are tapered outwardly and toward the blade and each has a surface transverse to and overlying the inside surface of the blade.  The transverse surfaces form knife edges at the inside surface of the blade and deflects outwardly cut portions of product being processed as they move through the blade and housing and limit their movement circumferentially with the blade.

Abstract: COAL LIQUEFACTION PROCESS WITH IMPROVED SLURRY RECYCLE SYSTEM              ABSTRACT OF THE DISCLOSURE           In a coal liquefaction process including recycle of a product slurry (14) comprising normally solid dis-solved coal and mineral residue, the minimum slurry recycle rate is determined by a pumpability constraint on the solids level of the slurry contained in the feed coal mixing vessel (6).  If the solids level in the feed coal mixing vessel (6) rises above the constraint level, the slurry recycle rate must increase.  For coals which generate a high mineral residue content, adequate dilu-tion of the slurry in the feed coal mixing vessel requires the slurry recycle rate to rise to an economically impracticable level.  In the present process, mechanical operability is improved and enhanced conversion of normally solid dissolved coal is achieved at a given constraint solids level by passing a portion of the liquefaction zone product slurry through a hydroclone (60) with the hydroclone overflow stream (61) constituting a second recycle slurry.  Deployment of the second recycle slurry increases the proportion of relatively small more catalytically active particles of mineral residue within the process.

Title: Method for processing solid raw materials  such as minerals and ores, more  particularly spathic magnesite ore
Inventor: BARTHA PETER
IPC: B03B1/02
Filed: 1979-12-14
Granted: 1982-10-12
Abstract: Abstract of the Disclosure A method of beneficiating spathic magnesite ore depends upon a special characteristic thereof that has been realized, namely that it decrepitates or disintegrates into grains when heated to temperatures below its chemical conversion reaction temperatures whereas its common impurities do not.          The ore is therefor heated to such a temperature below its calcining temperature and the resultant material graded according to grain size when the finer grain fraction will be enriched with the magnesite and the coarser grain fraction will be enriched with the usual calcite and/or dolomite impurities.          Depending upon the degree of purity required one would select smaller and smaller grain size fractions for increasing purity and, for example, one would then discard fractions of grain sizes greater than 5 mm, 3mm or 1 mm as waste.  The separated finer grain size fraction can be subjected to a second decrepitating step.
