  • In petroleum industry, it is desirable to produce lighter hydrocarbons such as gasoline, kerosene and gas–oil from unused heavy oils. Thus we have developed zirconia-supporting iron oxide catalysts View the MathML source to decompose petroleum residual oil (atmospheric distilled residual oil) with steam.

  • REFINING OPERATIONS Petroleum refining operations can be separated into five basic areas: 1. Fractionation (distillation) is the separation of crude oil in atmospheric and vacuum distillation towers into different "fractions" or "cuts." 2. Conversion processes change the size and/or structure of hydrocarbon molecules. These processes include: − Decomposition by thermal and catalytic cracking; − Unification through alkylation and polymerization; − Alteration with isomerization and catalytic reforming. ...

  • The different components of the rihzomes of Alpinia laosensis Gagnep was extracted by petroleum ether, ethyl acetate and methanol. From residue of the extract of petroleum ether, 3- (p-acetylphenyl)-3-metylcacboxyl-1-propen was isolated fraction distillation. The structure of the compound determined methods.
