ABSTRACT
There were sorptive measurements conducted. They were undertaken whith the use of liquid microburettes and coal samples from KWK: Jaworzno, Sośnica and Pniówek. Vapours of n-heptane and hept-1-ene were used as sorbates. In the investigation there was the hypothesis estimated: the sorption of unpolar substances vapours is mainly superficial and is significantly dependent on coal porosity. The course of sorption isotherms shows the influence of double bond on sorbent-sorbate system. It is connected with the value of sorption capacity of studied coals.

Sorpcja par cieczy apolarnych na węglu kamiennym o różnym składzie petrograficznym
sorpcja, węgiel kamienny
Przeprowadzono pomiary sorpcyjne, z zastosowaniem mikrobiuretek cieczowych, próbek węgli kamiennych pobranych z KWK Jaworzno, Sośnica, Pniówek. Jako sorbaty zastosowano pary: n-heptanu i hept-1-enu. Analiza uzyskanych wyników pozwoliła na przyjęcie następującej hipotezy: sorpcja par substancji apolarnych ma charakter głównie powierzchniowy i w istotny sposób zależna jest od porowatości węgli kamiennych. Przebieg izoterm sorpcji wskazuje także, iż obecność wiązania podwójnego wpływa na oddziaływania typu sorbent-sorbat, a tym samym wielkość chłonności sorpcyjnej badanych węgli.
