Sobre IBD

Głównym celem niniejszej pracy była ocena parametrów jakościowych węgla, przyległych matryc stałych (gliny, piasku i gleby powierzchniowej) oraz wody wodonośnej pobranej z różnych głębokości bloku III i V pola węglowego Thar, Sindh, Pakistan. Parametry jakościowe, takie jak skład pierwiastkowy, parametry proksymalne i końcowe próbek węgla zostały określone jako cechy fizykochemiczne. Zawartość wilgoci w próbkach węgla z pola węglowego Thar wskazuje, że bezpośrednie wykorzystanie węgla nie jest odpowiednie do wytwarzania energii. Skład mineralny został określony za pomocą SEM i dyfrakcji rentgenowskiej. Szczegółowo zbadano występowanie As i Hg w próbkach węgla z zagłębia węglowego Thar oraz ich zachowanie podczas spalania. Zawartość As i Hg w węglu i próbkach LMA zmierzono odpowiednio za pomocą spektrometrii absorpcji atomowej MHS-15 wodorek / generacja zimnych par. Wyniki LMA wskazują, że podczas spalania węgla >75% i >90% odpowiednio As i Hg może być uwalniane do atmosfery. Zawartość As i Hg w próbkach węgla z bloku III zagłębia węglowego Thar okazała się wyższa w porównaniu z blokiem V, co może wynikać z różnic w geochemicznym składzie mineralnym.
