Najdluzszy czas trwania patentu do 27 grudnia 1942 r.Znany jest juz sposób otrzymywania wodoru, polegajacy na tern, iz otrzymana podczas skraplania gazu z pieców kokso¬ wych frakcje metanowa przeprowadza sie ponad rozzarzonym do wysokiej tempera¬ tury koksem, W ten sposób udaje sie o- trzymac ponownie takaz ilosc wodoru, ja¬ ka zawarta jest w gazie z pieców kokso¬ wych w postaci pierwiastka.Doswiadczenie wykazalo, iz frakcje metanowa mozna wykorzystac znacznie le¬ piej, przetwarzajac ja w odpowiedni spo¬ sób w dwutlenek wegla i wodór zapomoca pary wodnej i tlenu, lub dowolnego z tych gazów oddzielnie.Metan reaguje np. z tlenem wedlug wzoru: | 2CH4 + 02 = 2CO + 4H2, a z para wodna zgodnie ze wzorem: Cff4 +H2 O = CO + 3 H2.Otrzymany w wyniku powyzszych dwóch reakcyj gaz, skladajacy sie prze¬ waznie z wodoru i tlenku wegla i bardzo malych ilosci dwutlenku wegla, poddany zostaje ponownie reakcji z para wodna, przyczem tlenek wegla z para wytwarza wodór wedlug wzoru:co + tf2o = co2 + #2.W ten sposób udaje sie z jednej czesci wagowej metanu otrzymac trzy, wzgled¬ nie cztery czesci wagowe wodoru. Miesza¬ nina dwutlenku wegla z wodorem rozdzie¬ la sie nastepnie w znany sposób zapomoca rozprezania z woda, doprowadzana pod cisnieniem i oczyszczania ostatecznego.Otrzymany w sposób powyzszy gaz od¬ dziela sie od wody, co zaleca sie uskutecz¬ niac zapomoca oziebiania go do tempera¬ tury okolo — 70°C, poczem za posrednic¬ twem dalszego oziebiania zapomoca cie¬ klego azotu lub parowania poszczególnych czesci skladowych, mieszanina gazów roz¬ klada sie na czesci skladowe.Nastepnie mieszanina gazów przemywa sie cieklym azotem, przyczem przemywa¬ nie zaleca sie uskuteczniac pod cisnieniem, wskutek czego oczyszcza sie ostatecznie od zanieczyszczen, pozostalych w miesza¬ ninie, np. metanu, tlenu i tlenku wegla.Jednoczesnie pewna czesc cieklego a- zotu parujac miesza sie z wodorem.Okolicznosc powyzsza mozna wyko¬ rzystac celem dalszego otrzymania amo- njaku, regulujac temperature cieklego a- zotu i cisnienie gazu tak, aby z wodorem mieszala sie scisle okreslona ilosc azotu, mianowicie trzy czesci wodoru winny byc mieszane z 1 czescia azotu.Wytworzona w ten sposób mieszanina moze byc nastepnie uzyta bezposrednio do wytwarzania amonjaku zapomoca syn¬ tezy pierwiastków. PLThe longest term of the patent, until December 27, 1942, the method of obtaining hydrogen is already known, consisting in the fact that the methane fraction obtained during the liquefaction of gas from coke furnaces is converted over the coke glowing to high temperature. - hold again as much hydrogen as is contained in the gas from coke ovens in the form of an element. Experience has shown that the methane fraction can be used much better by converting it in an appropriate manner into carbon dioxide and hydrogen as an element of steam water and oxygen, or either gas separately. Methane reacts with e.g. oxygen according to the formula: | 2CH4 + 02 = 2CO + 4H2, and water vapor according to the formula: Cff4 + H2 O = CO + 3 H2. The gas obtained as a result of the above two reactions, consisting mostly of hydrogen and carbon monoxide and very small amounts of carbon dioxide, it is reacted with steam again, whereby carbon monoxide with steam produces hydrogen according to the formula: co + tf20 = co2 + # 2. Thus it is possible to obtain three or four parts by weight of hydrogen from one part by weight of methane. The mixture of carbon dioxide and hydrogen is then separated in a known manner by means of dilution with water, supplied under pressure and a final purification. The gas obtained in this way is separated from the water, which is recommended to be effective without cooling it to temperature. At about -70 ° C, then by means of further quenching with liquid nitrogen or evaporation of the individual components, the gas mixture decomposes into its constituent parts. The gas mixture is then washed with liquid nitrogen, washing it is not recommended it becomes effective under pressure, as a result of which it is finally cleaned of impurities remaining in the mixture, such as methane, oxygen and carbon monoxide. - anyway, regulating the temperature of the liquid nitrogen and the gas pressure so that a strictly defined amount of nitrogen is mixed with the hydrogen, namely three c The hydrogen extracts should be mixed with 1 part nitrogen. The mixture produced in this way can then be used directly for the production of ammonia by means of an elemental synthesis. PL
