Abstract
(57) KIVONAT Eljárás szénhidrőgének termikűs krakkőlására őly módőn, hőgy egyvízgőzmentes szénhidrőgén tápáramőt a reakciótérben lamináris áramlástelőidéző sebességgel vezetnek át egy kívülrő fűtött, katalizátőrmentesreakciótéren, amelynek fűtött felület : térfőgat aránya 3 cm–1-nélnagyőbb. Ezzel a megőldással növelhető a reakció termikűs hatásfőka,és csökkenthetők a környezetszennyezési prőblémák. ŕ
Claims (10)
- SZABADALMI IGÉNYPONTOK1. Eljárás szénhidrogének termikus krakkolására, azzal jellemezve, hogy egy lényegében vízgőzmentes szénhidrogén-tápáramot a reakciótérben lényegében lamináris áramlást előidéző sebességgel vezetünk át egy kívülről fűtött, katalizátormentes reakciótéren, amelynek fűtött felület: térfogat aránya 3 cm '-nél nagyobb.
- 2. Az 1. igénypont szerinti eljárás, azzal jellemezve, hogy a reakciótéren hígítószerként hidrogént vagy metánt tartalmazó tápáramot vezetünk keresztül.
- 3. Az 1. vagy 2. igénypont szerinti eljárás, azzal jellemezve, hogy olyan reakcióteret használunk, amelynek a krakkolás alatt lévő gáznak kitett felületei az adott reakcióhőmérsékleten ismertek a szénhidrogének reakcióival szemben.
- 4. A 3. igénypont szerinti eljárás, azzal jellemezve, hogy olyan reakcióteret használunk, amelynek a krakkolás alatt lévő gáznak kitett felületi szilícium-dioxidból, szilícium-karbidból vagy rézből készültek, vagy ilyen anyagból készült nemporózus bevonatot hordoznak.
- 5. Az 1—4. igénypontok bármelyike szerinti eljárás, azzal jellemezve, hogy a reakcióteret a reakciótértől vékony fallal ellátott futőtéren átáramoltatott fűtőközeggel fíitjük.
- 6. Az 5. igénypont szerinti eljárás, azzal jellemezve, hogy olyan fűtőteret használunk, amelynek felületein égést katalizáló anyagból készült bevonat van, és a fűtőtéren tüzelőanyag/levegő keveréket átvezetve legalább a hő egy részét a fütőtérben végbemenő égetéssel teremtjük.
- 7. Az 1-6. igénypontok bármelyike szerinti eljárás, azzal jellemezve, hogy egymással párhuzamosan elrendezett reakcióterek sokaságát használjuk.
- 8. A 7. igénypont szerinti eljárás, azzal jellemezve, hogy egymástól távköztartókkal elválasztott párhuzamos lemezekből kialakított reaktort használunk, ahol a szomszédos lemezek közötti térközök váltakozva reakciótereket és fűtőtereket alkotnak.
- 9. A 8. igénypont szerinti eljárás, azzal jellemezve, hogy olyan reaktort használunk, ahol a lemezek - következésképpen a reakcióterek és a futőterek is - nyújtott téglalap alakúak, az egyedi terek átlósan szemben fekvő sarkainál belépő nyílás van kialakítva a reagensáram, illetve a fűtőközeg számára, és a belépő nyílások a téglalap egyik rövidebb oldalának szomszédos sarkainál vannak kialakítva.
- 10. A 8. vagy 9. igénypont szerinti eljárás, azzal jellemezve, hogy olyan reaktort használunk, ahol a reaktort alkotó szerkezet a belépő és kilépő járatoknál össze van kapcsolva, és ezt a reaktort a reakció nyomásánál nagyobb nyomású gázzal töltött tárolóedénybe helyezzük.
