The title compound pteleifolosin C, C(21)H(20)O(7), was isolated from the petroleum ether-soluble fraction of an indigenous Chinese tree Melicope pteleifolia (Rutaceae). The dihedral angle between the benzene rings is 2.7 (2)°. Intra-molecular O-H⋯O hydrogen bonds occur. In the crystal, mol-ecules are linked by inter-molecular O-H-O hydrogen bonds.

The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are clas...

Blends of bitumen, clay, and quartz in water are obtained from the surface mining Athabasca Oil Sands. To facilitate its transportation through pipelines, this mixture is usually diluted with locally produced naphtha. As a result this, naphtha has to be recovered later, recovery unit (NRU). The NRU process complex one requires knowledge Vapour-Liquid-Liquid Equilibrium (VLLE) thermodynamics. pr...

In the title compound, C(11)H(11)NOS(2), the benzine ring is coplanar with the thia-zole ring, making a dihedral angle of 0.81 (1)°. In the crystal, adjacent mol-ecules are connected into a helical chain along the b axis by S⋯S contacts [3.4345 (18) Å]. These helical chains are further assembled into a three-dimensional supermolecular network by inter-molecular C-H⋯O hydrogen bond between aroma...

Hydrogen is the most environmentally friendly fuel and can be efficiently used for stationary power and mobile applications. When burned or oxidized, it generates water as the only emission (small amounts of NOx are generated during the combustion process but can be controlled to very low levels). At present, hydrogen is produced almost entirely from fossil fuels such as natural gas, naphtha, a...

A methodology has been developed for predicting incident thermal radiation levels around pool fires, following accidental spillages of flammable liquids into bunded areas. A realistic representation of the flame shape has been developed using new correlations for predicting the flame geometry. The model has been validated against data from a wide range of experiments and good agreement obtained...

The present study describes the application of Fischer Tropsch biowaxes as a feedstock in a pilot-scale hydroprocessing unit at operating conditions very similar to industrial size hydrotreating plants of traditional refineries. The project focus on a future coprocessing of biowax/gasoil blends due to produce bio-products derived from lignocellulosic biomass: crack gases, naphtha, kerosene, die...
