Studies on screening and characteristics of lubrication oil degrading strains;

In order to treat wastewater containing lubrication oil by degrading bacteria, lubrication oil No.

Adsorption properties of machine oil on exfoliated graphite;

An experimental bacteria community was cultured and prepared in the pelroleum-fouling soil;through sieving and acclimatization,a compound bacteria community could be acquired,which can be carried out growing metabolism with machine oil as sole carbon.

32(China) machine oil in carbon dioxide were determined with a recirculation apparatus at temperatures 298 2K,313 2K and 323 2K,and under pressure range of 7MPa to 15MPa.

Reason analysis and countermeasures of too low lubricating oil pressure for DF_(4B) locomotive diesel engine;

Reason analysis and countermeasures of NPT5 air compressor lubricating oil emulsification;

Reason analysis and improvement measures of difficult start and shutdown during returning handle of DF_4 locomotives due to lower lubricating oil pressure;

Adsorption kinetics and thermodynamics for removal engine oil from aqueous solution using chichen feathers;

Through ACEA OM602A engine bench test and field tests,it was confirmed by Chevron Oronite Company that sulfur content in diesel oil significantly influenced engine oil TBN depletion,and low sulfur resulted in low TBN depletion.

The copper ion content is determined with direct spectrophotometry after the engine oil was incinerated,dissolved with acid and developed with Neocuproin-Hydroch lorid Monohydrat.
