Abstract

Process for completely utilising pure synthesis gas obtained by high temperature recycling of waste comprises bombarding the synthesis gas obtained with water vapour in a catalytic process to convert CO in the synthesis gas into CO2 and H2, to feed the remaining residual gas back to the high temperature reactor, to separate the main product consisting of H2, CO and CO2 by pressure swing adsorption into H2, CO and CO2 and utilise.

Description

Predložený vynález si kladie za úlohu vyvinúť spôsob, pri ktorom sa celkom látkovo využije čistý syntézny plyn a nevzniknú žiadne emisie.SUMMARY OF THE INVENTION It is an object of the present invention to provide a process in which pure synthesis gas is utilized wholly in substance and no emissions are generated.

Podlá vynálezu sa 'úloha rieši znakmi uvedenými v charakterizujúcej časti nároku 1.According to the invention, the object is solved by the features set forth in the characterizing part of claim 1.

Výhodné ďalšie riešenia a prevedenia tejto úlohy vyplývajú z podnárokov.Advantageous further solutions and embodiments of this task arise from the sub-claims.

Príklady vyhotovenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Podlá vynálezu sa tak navrhuje premeniť čistý syntézny plyn, ktorý pochádza prednostne z procesu, popísanom v patentovej prihláške DE 41 30 416 Cl, aspoň sčasti na CO2 a vodík. Obzvlášť je potrebné vyzdvihnúť, že zostávajúce odpadové plyny môžu byť vedené späť do vysokoteplotného reaktora, a že proces prebieha bez emisií. Premenené komponenty sa vedú na ďalšie využitie.According to the invention, it is thus proposed to convert the pure synthesis gas which preferably originates from the process described in patent application DE 41 30 416 C1, at least in part to CO 2 and hydrogen. In particular, it should be pointed out that the remaining waste gases can be recycled to the high temperature reactor and that the process is emission-free. The transformed components are led for further use.

Výhodná forma prevedenia je v tom, že čistý syntézny plyn, ktorý sa skladá v podstate z vodíka, oxidu uhličitého a oxidu uholnatého, je potrebné nasýtiť v katalytickom procese vodnou parou, aby sa oxid uholnatý, obsiahnutý v syntéznom plyne, úplne premenil na vodík a oxid uhličitý (CO + H2O --> H2 + CO2). Obe plynné zložky, vodík i oxid uhličitý, môžu byť oddelené všeobecne známymi spôsobmi, ako napr. v absorpčnom zariadení Preasuŕe Swing a významne využité.A preferred embodiment is that the pure synthesis gas, which consists essentially of hydrogen, carbon dioxide and carbon monoxide, must be saturated with steam in the catalytic process to completely convert the carbon monoxide contained in the synthesis gas to hydrogen and carbon dioxide (CO + H 2 O -> H 2 + CO 2 ). The two gaseous components, hydrogen and carbon dioxide, can be separated by generally known methods such as e.g. in the Preasure Swing absorber and significantly used.

Oxid uhličitý môže byt zahustený, ochladený a použitý ako suchý lad.The carbon dioxide can be concentrated, cooled and used as dry ice.

Vodík je možné využiť látkovo alebo energeticky. Ak sa vodík použije ako palivo alebo pohonná látka, je možné získať absolútne bezemisný nosič, pretože pri energetickom použití vodíka vzniká výlučne voda ( 2 H2 + 02 --> H20).Hydrogen can be used in either substance or energy. If hydrogen is used as a fuel or propellant, it is possible to obtain an absolutely emission-free carrier, since the energy use of hydrogen produces only water (2 H 2 + 0 2 -> H 2 0).

Ak sa vodík použije namiesto fosílneho paliva alebo pohonných hmôt, nenastáva zaťaženie životného prostredia, ktoré nutne pri použití fosílneho paliva alebo pohonných hmôt vzniká. Pretože suroviny, z ktorých sa získavajú fosílne alebo pohonné hmoty, sú obmedzené, môžu byť tieto účelne využité.If hydrogen is used in place of fossil fuel or fuel, there is no environmental burden that is necessarily incurred when fossil fuel or fuel is used. Since the raw materials from which fossil or fuel fuels are obtained are limited, they can be used effectively.

Vodík môže byt okrem toho použitý energeticky na výrobu elektrickej energie v palivových článkoch. Palivové články majú v porovnaní s konvenčnými elektrárenskými článkami nielen vyšší stupeň účinnosti, ale okrem toho palivové články produkujú elektrický prúd bez vzniku nejakej škodliviny.In addition, hydrogen can be used energetically to generate electricity in fuel cells. Fuel cells not only have a higher degree of efficiency than conventional power cells, but in addition fuel cells produce electricity without creating any pollutants.

Vodík môže byť použitý na látkové využitie, hydrogenačných a syntéznych procesoch. Pri hydrogenácii sa prítomné organické molekuly pri definovaných teplotách obohatia vodíkom.Hydrogen can be used for substance utilization, hydrogenation and synthesis processes. During hydrogenation, the present organic molecules are enriched with hydrogen at defined temperatures.

napríklad v organickej tlaku a prifor example at organic pressure and at

Po anorganickej vodíkom na kovy (napr.After inorganic hydrogen to metals (e.g.

hydrogenácii sa redukujú W03 + 3H2 —> W + H2).hydrogenation are reduced (W 3 + 3 H 2 -> W + H 2 ).

oxidy kovovmetal oxides

Syntézou môže byt z vodíka a dusíka vyrobený amoniak. Najmä ak je treba zdôrazniť, že kyslík, potrebný na splyňovanie odpadu, sa získa v rozkladnom zariadení vzduchu, pričom odpadá aj dusík, ktorý je možné hospodárne využiť na syntézu amoniaku. Najmä je výhodné, že rozkladné zariadenie vzduchu je už súčasťou prevádzky.Ammonia can be produced from hydrogen and nitrogen by synthesis. In particular, it should be pointed out that the oxygen required for the gasification of the waste is obtained in an air decomposition plant, and nitrogen which can be used economically for the synthesis of ammonia is also eliminated. In particular, it is advantageous that the air decomposition device is already in operation.

Ak má byt vodík použitý na výrobu metanolu, je účelné, aby sa oxid uhličitý, prítomný v syntéznom plyne, premenil prívodom vodnej pary na vodík a oxid uhoľnatý do takej miery, až ich pomer v syntéznom plyne dosiahne hodnotu 2 : 1 (čiastočná konverzia).If hydrogen is to be used for the production of methanol, it is expedient for the carbon dioxide present in the synthesis gas to be converted into hydrogen and carbon monoxide by supplying water vapor to such an extent that its ratio in the synthesis gas reaches 2: 1 (partial conversion) .

Nakoniec sa oxid uhličitý všeobecne známymi spôsobmi oddelí a vodík s oxidom uhoľnatým sa podrobí syntéze za vzniku metanolu.Finally, the carbon dioxide is separated by generally known methods and hydrogen with carbon monoxide is synthesized to give methanol.

Látkovým využitím vodíka sa získavajú chemické suroviny, schopné skladovania a transportu, ktoré môžu byt mnohostranne využité.The use of hydrogen by the substance produces chemical raw materials, capable of being stored and transported, which can be used in many ways.
