Analogue ionic liquids for the separation and recovery of hydrocarbons from particulate matter
Systems, methods and compositions for the separation and recovery of hydrocarbons from particulate matter are herein disclosed. According to one embodiment, a method includes contacting particulate matter with at least one analogue ionic liquid. The particulate matter contains at least one hydrocarbon and at least one solid particulate. When the particulate matter is contacted with the analogue ionic liquid, the hydrocarbon dissociates from the solid particulate to form a multiphase system.
