Effects of the addition of coal tar pitch-based mesocarbon microbeads on the preparation of mesophase pitch [PDF]
E3S Web of Conferences, 2021 Mesophase pitch was prepared by co-carbonization of the hydrocracking tail oil (HCTO) and coal tar pitch-based mesocarbon microbeads (MCMB). The effects of the addition amount of coal tar-based MCMBs on the C/H atomic ratio, softening point, carbon ...

Modelling In-situ Upgrading of Heavy Oil Using Operator Splitting Methods [PDF]
, 2014 Heavy oil and oil sands are important hydrocarbon resources that account for over 10 trillion barrels (Meyer et al., 2007), nearly three times the conventional oil in place in the world.

Oil & Gas Science and Technology, 2004 Heavy crude oils cannot be transported by pipeline without a prior reduction of their viscosity. This is commonly obtained by blending the oil with light hydrocarbons. In that case, the resulting viscosity of the mixture depends only on the dilution rate, on the respective viscosities and densities of the oil, and of the diluent.

Heavy oil production with energy effective steam-assisted gravity drainage [PDF]
, 2016 In reservoirs with extra heavy oil and bitumen, thermal methods are used to reduce the viscosity, in order to extract the oil. Steam-assisted gravity drainage (SAGD) is a thermal method where continuous steam injection is used.

Ethylene Separation via Hydrate Formation in W/O Emulsions
Energies, 2015 An hybrid absorption-hydration method was adopted to recover C2H4 from C2H4/CH4 binary gas mixtures and the hydrate formation conditions of C2H4/CH4 mixtures was studied experimentally in diesel in water (w/o) emulsions. Span 20 at a concentration of 1.0

Aquatic Effects of a Localized Oil Spill on Lake Conway, AR and Its Tributaries [PDF]
, 2015 Oil spills, no matter where they occur, elicit environmental concern and avoiding these disasters should be a priority. Old pipelines that are not regularly maintained and carry large amounts of crude oil long distances are of particular concern.

The Acoustic Properties of Sandy and Clayey Hydrate-Bearing Sediments
Energies, 2019 Natural gas hydrates samples are rare and difficult to store and transport at in situ pressure and temperature conditions, resulting in difficulty to characterize natural hydrate-bearing sediments and to identify hydrate accumulation position and ...
