Recovery of Heavy Oil from Heavy Oil Sorbed Exfoliated Graphite.
NIPPON KAGAKU KAISHI, 2000 膨張黒鉛は,大きな重油収着能を示し,自身重量の80倍程度のA重油あるいは原油を収着した膨張黒鉛から,圧搾法で収着した重油のおよそ80%を,また吸引濾過法でも収着した重油の50-70%を回収することを見いだした。しかしながら,吸引濾過法による回収では,粘性の高いB重油およびC重油では,回収がほぼ不可能であった。この吸引濾過法では,膨張黒鉛特有のかさ高さを壊すことはなく,再収着に使用できた。しかしながら,回収を繰り返すことにより,収着量,回収量は減少していった。一方,回収された重油ともとの原油との間には,炭化水素組成分子量および水分含有量に差は認められず,回収された重油は,そのまま使用可能であることが明らかとなった。

Advanced Functional Materials, EarlyView.Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

Degradation of Dispersants and Dispersed Oil [PDF]
, 2011 Chemical oil dispersants are proprietary mixtures of surfactants and solvents which are directly applied to a spill in order to reduce the natural attractive forces of the oil. When oil treated with dispersants is exposed to mixing energy, typically from

Monitoring viscosity changes from time-lapse seismic attenuation: case study from a heavy oil reservoir [PDF]
, 2015 Heating heavy oil reservoirs is a common method for reducing the high viscosity of heavy oil and thus increasing the recovery factor. Monitoring of these viscosity changes in the reservoir is essential for delineating the heated region and controlling ...
