The volume removal capacity of adsorbent resin loaded with nitrogenous polymer increases markedly, reaching 3.

Natural nitrogenous compounds from the South China Sea marine sponge Clathria fasciculate;

Distribution of nitrogenous compounds and hydrocarbon migration in Zhenbei Oilfield

39°P), alcohol content and real attenuation, total acidity and pH value, viscosity, nitrogenous compounds (total nitrogen, high molecule nitrogen, middle molecule nitrogen, low molecule nitrogen and α-amino nitrogen), β-glucan and arabinoxylan.

The effects of nitrogen-containing compound on the oxidative stability of petroleum products were intro- duced.

Then it is pointed out that nitrogen-containing compounds are the products of rock-forming diagenesis of sedimentary organic matter and that the content and composition are apparently controlled by organic maturity.

Distribution of nitrogen compounds in oils and reservoir filling direction in Hadexun and its adjacent oilfields,Tarim Basin,NW China;

Neutral nitrogen compounds distribution and petroleum migration of Yanchang formation,Triassic system,Ordos Basin.

This paper analyzes some geochemical information of Jurassic reservoir in the Yanqi basin,which includes crude oil physical property,pyrrolic nitrogen compounds and isotopic age of autogenetic illite,and also discusses the oil and gas migration direction.

Effects of different nitrogenous compounds on growth and nodulation of Abrus cantoniensis;

Effect of vineyard grass covering with alfalfa (Medicago sativa) on nitrogenous compound of grape berry and wine in grape cuitivar cabernet sauvignon;

According to the comprehensive a-nalysis on the geochemical features of crude oil, oil and gas inclusions and nitrogenous compound in crude oil, oil source, reservoir forming time, direction of oil-gas injection and migration of crude oil in Luliang oilfield are determined.
