Selective oil agglomeration in Sırnak asphaltite beneficiation

Effect of stirring time on oil agglomeration of fine coal

“…As seen from Figure 4, the combustible recovery generally increased with increasing stirring time. This can be attributed to the enhancement of collisions between particles and micro-agglomerates, and thus the agglomerates consolidate and become spherical (Abakay, Ayhan, and Kahraman, 2004). Figure 4 also shows that the ash content of the agglomerates decreased with increasing stirring time up to 30 minutes.…”

“…When such particles collide with each other, the oil droplets attached to the hydrophobic particles can merge and bridge the particles into larger agglomerates (Laskowski and Yu, 2000). The agglomerated hydrophobic particles can be separated from the hydrophilic materials by screening, or alternatively by flotation and skimming (Abakay, Ayhan, and Kahraman, 2004).…”

“…Abakay ve arkadaşlarının [52], çalışmasında Şırnak asfaltitlerinin aglomerasyon yöntemi ile temizlenmesi araştırılmıştır. Deneysel çalışmalarda sırasıyla; kül %44,8, kükürt %6,0, uçucu madde %38,0 ve sabit karbon oranı %17,2 içerikteki asfaltit numunesi üzerinde çalışma yapılmıştır.…”

Flash pyrolysis of Silopi asphaltite in a free-fall reactor under vacuum

“…Among them, asphaltite is a complex material consisting of compounds in the range from non-polar aliphatic and naphthenic hydrocarbons to highly polar aromatic molecules containing heteroatoms such as oxygen, nitrogen and sulfur [1], which have high reserve in the southeastern of Turkey (Silopi, Şırnak, Avgamasya, etc. ), approximately 77.5 million tonnes [2,3].…”

“…Generally the relevant literature for utilization of asphaltite have included details such as the desulfurization [2], oil aglomerization of asphaltite [1], characterization of asphaltite structure [4] and pyrolysis in different reactor(s) [3,[5][6][7].…”
