Title: Postupak dobijanja čistog magnezij oksida, amorfnog silicij dioksida i koncentrata primjesa i pratećih elemenata serpentinita sa sadržajem serpentina 90% otapanjem sonom kiselinom

Abstract: POSTUPAK DOBIJANJA ČISTOG MAGNEZIJ OKSIDA, AMORFNOG SILICIJ DIOKSIDA I KONCENTRATA PRIMJESA I PRATEĆIH ELEMENATA SERPENTINITA SA SADRŽAJEM SERPENTINA 90% OTAPANJEM SONOM KISELINOM, ovim pronalaskom razradjen je postupak dobivanja magnezij oksida, silicij dioksida, željezo (III) oksida i koncentrata primjesa i pratećih elemenata iz serpentinita u kojima je visok sadržaj serpentina, kao i iz serpentina serpentinskih haldi. Magnezij iz serpentina i topive primjese serpentinita otapaju se s HCl, dok se netopive primjese izdvajaju zajedno s gelom SiO2. Izdvojeni SiO2 je disperzan, s veličinom čestica ispod 0,1 um, specifičnom površinom 360-400 m2/g i reaktivan. Gravitacijskom separacijom ili otapanjem SiO2, odvijaju se primjese koje se na taj način koncentriraju. U koncentratu se, ovisno o prirodi i sastavu serpentinita, nalaze različiti elementi medju kojima često i elementi grupe. Sukcesivnim podizanjem pH vrijednosti otopine, otopljene primjese i prateći elementi serpentinita izdvajaju se taloženjem kao hidroksidi odnosno oksihidrati. Tako se koncentriraju Fe, Ni, Co i drugi elementi. Otopina magnezij klorida koncentrira se uparavanjem i dalje razlaže do MgO, zagrijavanjem na 800-900В°C. Dobiveni MgO je visoke čistoće (MgO 99 %).

Patent YU-92389-A (YU)
Inventor: ALPAR T
IPC: C04B40/02
Filed: 1989-05-05
Abstract: To produce articles, especially building elements from a material mixture which contains cement or/and lime as binder and is to be cured, the raw mixture is filled continuously into a template (1) and pressed in by ramming. CO2 gas at superatmospheric pressure flows through the mixture in the template space (5), whereby the mixture is cured by means of an instantaneous carbonating reaction to give a moulded article. Escape of the CO2 gas in the surroundings of the feed opening of the template (6) is prevented by making the material virtually gas-tight by mechanical means, for example by ramming it in. In the direction of the outlet opening (7), the pressure of the CO2 gas is reduced and, in the region of the outlet opening, the quantity of CO2 gas fed is then only just that which is still required for the chemical reaction. Consequently, there is not even a gas loss here. The continuously issuing article is cut to measure, for example by means of a saw (21).

Abstract: ABSTRACT OF THE DISCLOSURE:     A catalytic reactor for the catalytic reaction of SO2 to SO3, comprising a plurality of separate reaction chamber means each containing a hollow central column and at least three annular catalyst tray means vertically spaced apart one over the other with the inner edges thereof in contact with the central column.  Each annular catalyst tray means consists of catalyst means and gas-permeable plate means.  A first gas space is provided before the uppermost catalyst tray means, as well as common gas spaces between adjacent catalyst tray means, and a last gas space after the lower-most catalyst tray means.  The reactor includes inlet means for feed-ing partial streams of SO2-containing gas into alternate gas spaces, the partial streams fed into the common gas spaces being divided such that a portion flows through the upper tray means and the balance through the lower means; the gas spaces downstream and adjacent to the alternate gas spaces communicate with inlets in the hollow column for allowing partial streams of gases to enter the hollow column after they pass through a catalyst tray means.  The hollow column has a common outlet for combined partial gas streams communicating with a gas space other than an alternate gas space.          The reactor also includes conduit means for supplying the gases to the inlet means of the alternate gas spaces and conduit means connect-ed to the gas space in communication with the common outlet of the central column, as well as cooling means for cooling the combined gases flowing from one reaction chamber means to the next via the conduit means connected to the gas space in communication with the common outlet of the central column. The catalytic reactor of the invention can be used  for throughput rates up to about 500,000 standard cubic meters per hour.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for the controlled oxidation of coke from a spent catalyst and the essentially complete conversion of carbon monoxide resulting from the oxidation of coke to pro-duce regenerated catalyst and spent regeneration gas.       The apparatus comprises in combination a spent-catalyst receiving chamber for containing a dense bed of fluidized catalyst in which chamber spent catalyst is oxidixed to produce regenerated catalyst and partially spent regeneration gas; a transfer conduit through which said gas and said catalyst pass and in which carbon monoxide is essentially completely convert-ed to carbon dioxide to produce spent regeneration gas and regenerated catalyst at an increased temperature; a regenerated-catalyst receiving chamber for containing a dense bed of reg-enerated catalyst and in which spent regeneration gas and re-generated catalyst are separated; and, an internal regenerated-catalyst recycle means in communication with both beds by which hot regenerated catalyst can be recycled within the apparatus from the dense bed of regenerated catalyst in the regenerated-catalyst receiving chamber to the dense bed of catalyst in the spent-catalyst receiving chamber in amounts to control the temper-ature and hence the rate of coke oxidation in the spent-catal-yst receiving chamber.       In the apparatus of my invention, residual coke on re-generated catalyst can therefore be significantly reduced or controlled to low levels as desired.  The CO burning rate in the transfer conduit is also increased because of the higher inlet temperature and the CO concentration in the spent regener-ation gas leaving the apparatus is therefore reduced.         A particularly unique feature of the apparatus is the internal regenerated-catalyst recycle means which requires no expansion joints nor movable flow control means and which can be installed without cutting into either chamber of the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention is concerned with a method of curing solvent-free inks by application of a powdered resin to a freshly printed surface.  Powder, which does not adhere to the ink, is removed and the printed surface then is passed through a heating tunnel where the resin melts, thereby curing the ink.  Optionally, the printed surface may be leveled mechanically following curing.  Such leveling produces a higher gloss.  Air pollution which normally is caused by solvent fumes in conventional processes is eliminated by this method.  Moreover, heat energy is con-served as the need to vaporize a solvent and to carry-off the heated vapors is eliminated.
