Yize ilusizo ekuphenduleni kuze kufike cishe kuma-degree angama-600 C., izinto zokusebenza ze-GB Patent 2210286 zinenkinga enkulu emazingeni okushisa aphezulu. Ukutholakala kwamandla kazibuthe womgogodla we-ferromagnetic kuzokwehla kakhulu emazingeni okushisa aphezulu. Ngokusho kuka-Erickson, CJ, “Handbook of Heating for Industry”, amakhasi 84-85, amandla kazibuthe wensimbi aqala ukwehla abe ngu-600 C futhi adlule ngempumelelo ngo-750 C. Njengoba, ekuhlelweni kuka-GB '286, amandla kazibuthe Inkambu embhedeni wokudonsa incike ekuthambekeni kwamandla kazibuthe womgogodla we-ferromagnetic, lelo lungiselelo ngeke lishise ngempumelelo isisusa emazingeni okushisa angaphezu kuka-750 C, ingasaphathwa eyokufika kokukhulu kune-1000 C edingekayo ekukhiqizeni i-HCN.

Izinto ezisetshenziswayo ze-GB Patent 2210286 nazo zikholelwa ukuthi azikulungele ukwenziwa kwe-HCN. I-HCN yenziwa ngokuphendula i-ammonia negesi ye-hydrocarbon. Kuyaziwa ukuthi i-iron ibangela ukubola kwe-ammonia emazingeni okushisa aphakeme. Kukholakala ukuthi i-iron ekhona kumgogodla we-ferromagnetic kanye nasekwesekeni kokuqina ngaphakathi kwegumbi lokuphendula le-GB '286 kungadala ukubola kwe-ammonia futhi kungavimbela, esikhundleni sokukhuthaza, ukusabela okufunwayo kwe-ammonia nge-hydrocarbon ukwakha i-HCN.

IHydrogen cyanide (HCN) iyikhemikhali elibalulekile elisetshenziswa kakhulu ezimbonini zamakhemikhali nezimayini. Isibonelo, i-HCN yinto eluhlaza yokwenziwa kwe-adiponitrile, i-acetone cyanohydrin, i-sodium cyanide, kanye nabaxhumanisi ekwenziweni kwezibulala-zinambuzane, imikhiqizo yezolimo, ama-chelating agents kanye nokuphakelwa kwezilwane. I-HCN iwuketshezi olunobuthi kakhulu olubila kuma-26 degrees C, futhi ngenxa yalokho, lukhonjelwe emithethweni eqinile yokupakisha nokuhamba. Kwezinye izinhlelo zokusebenza, i-HCN iyadingeka ezindaweni ezikude kude nezindawo ezinkulu zokukhiqiza ze-HCN. Ukuthunyelwa kwe-HCN ezindaweni ezinjalo kubandakanya izingozi ezinkulu. Ukukhiqizwa kwe-HCN ezindaweni ezizosetshenziswa kuzo kungavikela izingozi ezitholakala ekuthuthweni, ekugcineni nasekuphatheni kwayo. Ukukhiqizwa okuncane esizeni kwe-HCN, kusetshenziswa izinqubo zobuciko zangaphambili, bekungeke kube nokwenzeka kwezomnotho. Kodwa-ke, isikali esincane, kanye nesilinganiso esikhulu, ukukhiqizwa kwesiza kwe-HCN kuyenzeka ngokwezobuchwepheshe nangokwezomnotho kusetshenziswa izinqubo nezinto ezisetshenziswayo zalokhu okusunguliwe.

I-HCN ingakhiqizwa lapho izinhlanganisela eziqukethe i-hydrogen, i-nitrogen, ne-carbon zihlanganiswa emazingeni okushisa aphezulu, noma zingenayo i-catalyst. Isibonelo, i-HCN ivame ukwenziwa ukusabela kwe-ammonia ne-hydrocarbon, ukusabela okuphela kakhulu emzimbeni. Izinqubo ezintathu zokuhweba zokwenza i-HCN yi-Blausaure aus Methan und Ammoniak (BMA), i-Andrussow, nezinqubo zeShawinigan. Lezi zinqubo zingahlukaniswa ngendlela yokukhiqiza ukushisa nokudlulisa, nokuthi i-catalyst isetshenzisiwe yini.

Inqubo ye-Andrussow isebenzisa ukushisa okwenziwe ukushiswa kwegesi ye-hydrocarbon ne-oxygen ngaphakathi kwevolumu yesikhungo ukupha ukushisa kokuphendula. Inqubo ye-BMA isebenzisa ukushisa okwenziwe ngenqubo yomlilo yangaphandle ukushisa indawo engaphandle yezindonga zesiphenduli, yona yona efudumeza ingaphakathi lezindonga zokuphendula futhi ngaleyo ndlela inikeze ukushisa kokuphendula. Inqubo yeShawinigan isebenzisa amandla kagesi ageleza ngama-electrode embhedeni ophuzwayo ukuhlinzeka ukushisa kokuphendula.

Enqubeni ye-Andrussow, inhlanganisela yegesi yemvelo (ingxube yegesi ye-hydrocarbon ephezulu e-methane), i-ammonia, ne-oxygen noma nomoya kuyasetshenziswa lapho kukhona i-platinum catalyst. I-catalyst ngokuvamile iqukethe izingqimba eziningi ze-platinum / rhodium wire gauze. Ubuningi bomoya-mpilo bokuthi ukushisa okuyingxenye kwama-reactants kunika amandla anele ukushisa ama-reactants ekushiseni okusebenzayo okungaphezu kuka-1000 ° C. kanye nokushisa okudingekayo kokuphendula kokwakheka kwe-HCN. Imikhiqizo yokuphendula yi-HCN, H2, H2O, CO, CO2, futhi ilandelela amanani ama-nitrites aphezulu, okumele ahlukaniswe.

Enqubeni ye-BMA, inhlanganisela ye-ammonia ne-methane igeleza ngaphakathi kwamashubhu e-ceramic angenayo impophoma enziwe ngezinto zokushisa eziphikisayo. Ingaphakathi leshubhu ngalinye lifakwe ngaphakathi noma ligcwele izinhlayiya ze-platinum. Amashubhu abekwa esithandweni sokushisa okuphezulu futhi afudunyezwe ngaphandle. Ukushisa kwenziwa ngodonga lwe-ceramic kuya ku-catalyst surface, okuyingxenye ebalulekile yodonga. Ukuphendula kuvame ukwenziwa ngo-1300 ° C. njengoba ama-reactants axhumana ne-catalyst. Ukufudumala kokushisa okudingekayo kuphezulu ngenxa yokushisa okuphezulu okuphendulayo, ukushisa okukhulu kokuphendula, kanye nokuthi ukupheka kobuso be-catalyst kungenzeka ngaphansi kwezinga lokushisa lokuphendula, okuvimbela i-catalyst. Njengoba ithubhu ngayinye icishe ibe ngu-1 ″ ububanzi, kudingeka inani elikhulu lamashubhu ukuhlangabezana nezidingo zokukhiqiza. Imikhiqizo yokusabela yi-HCN ne-hydrogen.

Enqubeni yeShawinigan, amandla adingekayo ekuphenduleni kwenhlanganisela equkethe i-propane ne-ammonia anikezwa ngamandla kagesi ageleza phakathi kwama-electrode acwiliswe embhedeni oketshezi wezinhlayiya ze-coke non-catalytic. Ukungabikho kwe-catalyst, kanye nokungabikho komoya-mpilo noma umoya, kwinqubo yeShawinigan kusho ukuthi ukuphendula kufanele kuqhutshwe emazingeni okushisa aphakeme kakhulu, imvamisa kudlula ama-degree angama-1500 C. Amazinga aphezulu okushisa adinga ukubeka izingqinamba ezinkulu kakhulu izinto zokwakha zenqubo.

Ngenkathi, njengoba kudalulwe ngenhla, kuyaziwa ukuthi i-HCN ingakhiqizwa ukusabela kwe-NH3 kanye negesi ye-hydrocarbon, efana ne-CH4 noma i-C3H8, lapho kukhona i-Pt group catalyst yensimbi, kusenesidingo sokwenza ngcono ukusebenza kahle izinqubo ezinjalo, nezinye ezihlobene nazo, ukuze kuthuthukiswe ezomnotho zokukhiqizwa kwe-HCN, ikakhulukazi ukukhiqizwa okuncane. Kubaluleke kakhulu ukunciphisa ukusetshenziswa kwamandla nokuqhamuka kwe-ammonia ngenkathi kukhulisa izinga lokukhiqiza le-HCN ngokuqhathanisa nenani le-catalyst yensimbi eyigugu esetshenzisiwe. Ngaphezu kwalokho, i-catalyst akufanele iphazamise ukukhiqizwa kwe-HCN ngokukhuthaza ukusabela okungathandeki njengokupheka. Ngaphezu kwalokho, kuyadingeka ukwenza ngcono umsebenzi nempilo yama-catalysts asetshenziswe kule nqubo. Ngokuphawulekayo, ingxenye enkulu yokutshalwa kwezimali ekukhiqizeni i-HCN iku-catalyst yeqembu le-platinum. Ukuqanjwa kwamanje kushisa i-catalyst ngqo, kunokuba kube ngokungaqondile njengakubuciko bangaphambilini, futhi ngaleyo ndlela kufezekiswe lezi desiderata.

Njengoba kuxoxwe ngaphambili, ukufudumeza kokufakwa okuvama okuphansi kuqhathaniswa nokwaziwa ngokuhlinzeka ngokufana okuhle kokulethwa kokushisa emazingeni aphezulu wamandla ezintweni ezinemigwaqo ende kagesi yokuhamba. Lapho unikeza amandla okuphendula kumandla wegesi we-endothermic phase catalytic, ukushisa kudinga ukuhanjiswa ngqo ku-catalyst ngokulahleka kwamandla okuncane. Izidingo zokulethwa kokushisa okufanayo futhi okusebenzayo endaweni ephezulu, enendawo evumelana negesi kubonakala kungqubuzana namandla okushisa wokungeniswa. Ukuqanjwa kwamanje kusekelwe emiphumeleni engalindelekile etholwe ngokucushwa kwesiphenduli lapho i-catalyst inefomu lesakhiwo senoveli. Leli fomu lihlanganisa izici ze: 1) ubude bendlela yokuhamba kagesi esebenza kahle, esiza ukufudumeza okusebenzayo okusebenzayo kwe-catalyst ngendlela efanayo, kanye ne-2) i-catalyst enendawo ephezulu; lezi zici ziyasebenzisana ukwenza lula ukuphendula kwamakhemikhali endothermic. Ukushoda okuphelele kwensimbi egumbini lokuphendula kusiza ukukhiqizwa kwe-HCN ngokuphendula kwe-NH3 kanye negesi ye-hydrocarbon.
