The function of hydrocarbons and nitrogen oxides in photochemical smog formation and the formative process of ozone and peroxyacetyl nitrate are discussed.
Secondary in abundance are aromatic sester and sesquiterpenoid hydrocarbons,but aromatic diterpenoids, most of the regular PAH are found at trace levels only.
Main macerals of hydrocarbon generation are sporinite, cutinite, alginite, bituminite, liptodetrinite and desmocollnite in source rocks from Jurassic coal measure in Northwest China.
The auth or suggests that prebiological informational structures,gene predecessors and protoorganisms should be looked for among abiogenic ordered hydrocarbon molecul ar systems(hard bitumens).
The episodic flow of hydrocarbon migration and all geofluid and the episodic action of crust structure are complementary to each other and mutually determined.
Nonbiodegradable pollutants, such as certain chlorinated hydrocarbon pesticides (e.g.DDT) and heavy metals, such as lead, copper, and zinc in some industrial effluents, accumulate in the environment.
The company main product includes: High boiling point products and so on solvent series, plasticizer series, aromatic hydrocarbon series, Zhong propyl butyl-carbinol, 2- octanone and thiophen.
The result indicates that the main metabolic product of petroleum hydrocarbon degradation is acetic acid and surface active agent of glycolipid composed of fatty acid and rhamnose.
Casinghead gas is wet gas containing liquid hydrocarbons that can be removed from the gas by reducing the temperature or pressure on the gas with an absorption plant.
In the case of mudstone to be a source rock, the uncompacted mudstone would have a strong capability of hydrocarbon concentation sealing to seal gas in diffusive phase.
