Ukugqwala kwe-Hydrogen kungenzeka nge-ammonia synthesis, ukusabela kwe-hydrogen Susulfurization Hydrogenation and Petroleum Refing Units. I-Carbon yensimbi ayilungele ukusetshenziswa ekufakweni kwengcindezelo ephezulu ye-hydrogen ngenhla kwe-232 ° C. I-Hydrogen ingaphazamisa insimbi bese iphendula nge-carbide yensimbi emingceleni yokusanhlamvu noma ezindaweni zeparele ukukhiqiza i-methane. I-Methane (igesi) ayikwazi ukuxhaphaza ingaphandle lensimbi futhi iqoqe, ikhiqiza amabala amhlophe kanye nemifantu noma noma yile kwalokhu kuleli nsimbi.
Ukuze uvikele ukukhiqizwa kwe-methane, ukuthuthuka kufanele kuthathelwe indawo yi-carbides ezinzile, insimbi kufanele ingezwe ku-chromium, ku-vanadium, titanium noma i-drill. Kubhalwe phansi ukuthi ukwanda kokuqukethwe kwe-chromium kuvumela amazinga okushisa aphezulu wenkonzo kanye nengcindezi eyingxenye ye-hydrogen ukwakha i-chromium carbide kuleli nsimbi, nokuthi izinzile ngokumelene ne-hydrogen. Ama-chromium steel kanye nama-auntenitic ama-stainless ama-chromium aqukethe ama-chromium angaphezu kwe-12% amelana nokukhulisa izicelo zonke ezaziwayo ngaphansi kwezimo ezinzima zenkonzo (amazinga okushisa angenhla kwe-593 ° C).
Izinsimbi eziningiFuthi ama-alloys awaphenduli nge-nitrogen yamangqamuzana emazingeni okushisa aphezulu, kepha i-athomunic nitrogen ingasabela ngensimbi eminingi. futhi ungene ensimbi ukuze wakhe ungqimba lwe-brittle nitride elingaphezulu. I-iron, i-aluminium, titanium, i-chromium nezinye izinto ezengeziwe zingahileleka kulezi zinto ezisabele ngazo. Umthombo oyinhloko we-athomunic nitrogen ukuwohloka kwe-ammonia. Ukubola kwe-ammonia kwenzeka e-ammonia abaguquli, ama-armonia ekhiqiza ama-heater kanye nezinto zokuthwala i-nitriding asebenza ku-371 ° C ~ 593 ° C, umkhathi owodwa ~ 10.5kg / MM².
Kule moya, i-crobimium carbide ivela ngensimbi ephansi ye-chromium. Kungenzeka kufezeke nge-atomic nitrogen futhi ukhiqize i-chromium nitride, nokukhishwa kwekhabhoni ne-hydrogen ukukhiqiza i-methane, njengoba kushiwo ngenhla, noma kungavezwa amabala amhlophe, noma omunye wabo. Kodwa-ke, ngokuqukethwe kwe-chromium ngaphezulu kwe-12%, i-carbusides kulezi zinsimbi zizinze kakhulu kune-chromium nitride, ngakho-ke ukusabela kwangaphambilini akwenzeki, manje ama-steress asetshenziswa ezindaweni ezishisayo zama-ammonia.
Isimo sensimbi engenasici e-ammonia sinqunywa ngokushisa, ingcindezi, ukugxilwa kwegesi nokuqukethwe kwe-chromium-nickel. Ukuhlolwa kwensimu kukhombisa ukuthi izinga lokugqwala (ukujula kwensimbi eshintshiwe noma ukujula kwe-carburlization) ye-Ferrititic noma i-martensitic steress steres aphezulu kunelensimbi e-auntenitic engaphezulu kwe-auntenitic, amelana nokuqukethwe okuphezulu kwe-nickel. Njengoba okuqukethwe kukhulisa izinga lokukhulisa lenyuka.
Insimbi Engagqwali Engagqwali kumazinga aphezulu okushisa i-halogen vapor, ukugqwala kunzima kakhulu, i-fluorine iyalimala kakhulu kune-chlorine. Ngensimbi ephezulu ye-NI-C r
