Americko-izraelsk\u00e1 v\u00e1lka s \u00cdr\u00e1nem p\u0159it\u00e1hla ropu do pozornosti sv\u011bta kv\u016fli uzav\u0159en\u00ed Hormuzsk\u00e9ho pr\u016flivu. Kdy\u017e v\u00e1lka za\u010dala, myslel jsem si, \u017ee ropa je jen ropa. Dob\u0159e\u2026 Byl jsem nev\u011bdom\u00fd. Ale za posledn\u00ed \u010dty\u0159i m\u011bs\u00edce jsem se dozv\u011bd\u011bl docela dost od n\u011bkolika r\u016fzn\u00fdch odborn\u00edk\u016f v oboru. Chcete-li pochopit jeden z hlavn\u00edch d\u016fvod\u016f, pro\u010d Donald Trump podepsal memorandum o porozum\u011bn\u00ed, mus\u00edte pochopit, pro\u010d jsou USA z\u00e1visl\u00e9 na kysel\u00e9 rop\u011b, kter\u00e1 poch\u00e1z\u00ed z Persk\u00e9ho z\u00e1livu. Pokus\u00edm se to vysv\u011btlit jednodu\u0161e \u2013 asi 65 % americk\u00fdch rafin\u00e9ri\u00ed je navr\u017eeno ke zpracov\u00e1n\u00ed kysel\u00e9 ropy, zat\u00edmco americk\u00fd ropn\u00fd pr\u016fmysl produkuje prim\u00e1rn\u011b sladkou ropu. Kyselou ropu pot\u0159ebujeme k v\u00fdrob\u011b nafty a leteck\u00e9ho paliva. Uzav\u0159en\u00ed Hormuzsk\u00e9ho pr\u016flivu znamen\u00e1, \u017ee USA nebudou m\u00edt dostatek kysel\u00e9 ropy k udr\u017een\u00ed sou\u010dasn\u00e9 \u00farovn\u011b produkce nafty a leteck\u00e9ho paliva.

Ropa se klasifikuje podle dvou hlavn\u00edch os: hustoty (stupe\u0148 API dle American Petroleum Institute) a obsahu s\u00edry. \u201eLehk\u00e9\u201c ropy maj\u00ed vysok\u00fd stupe\u0148 API (kolem 35\u00b0 a v\u00fd\u0161e); \u201et\u011b\u017ek\u00e9\u201c ropy maj\u00ed vy\u0161\u0161\u00ed hustotu. \u201eSladk\u00e1\u201c ropa obsahuje m\u00e9n\u011b ne\u017e 0,5 hmotnostn\u00edch procent s\u00edry; \u201ekysel\u00e1\u201c ropa obsahuje v\u00edce \u2013 samotn\u00e1 specifikace SPR definuje kyselou ropu jako obsah s\u00edry mezi 0,5 a 2,0 procenty.<\/span><\/p>\n

Od konce 80. let 20. stolet\u00ed do prvn\u00ed poloviny 21. stolet\u00ed investovali provozovatel\u00e9 rafin\u00e9ri\u00ed pod\u00e9l americk\u00e9ho pob\u0159e\u017e\u00ed Mexick\u00e9ho z\u00e1livu des\u00edtky miliard dolar\u016f do hlubok\u00fdch konverzn\u00edch kapacit: koksoven, hydrokrak\u016f, fluidn\u00edch katalytick\u00fdch krak\u016f a hydrorafinac\u00ed.
