the method is used for the extraction of the c2 + or c3 + hydrocarbons from gas mixtures, which essentially light hydrocarbons and, if necessary, hydrogen or nitrogen. the gas mixture is first cooled and subjected to a phase, and the liquid fraction by rectification being cut.the gaseous ...
Ion-molecule reaction of CH3+, C2H5+, C3H5+ and C3H7+ with unsaturated C2, C3 and C4 hydrocarbonsThe reaction rate constants and product distributions for reaction of CH 3 + and C 2H 5 + with ethylene, C 2H 5 + with propene and cyclopropane, and C 3H 5 + and C 3H 7 + with ...
For C3–5 hydrocarbons (Fig. 2e), C3 products were significantly more prevalent than C4 and C5 products, with their FEs peaking at −2.2 VAg/AgCl, mirroring C2H4 behavior. The ratios of C2,3 hydrocarbons, analyzed at different potentials (Figure S2b), increased with more negative potentials...
Interestingly, a positive correlation was found between the diacid-C/WSOC ratios (r = 0.75; p = 0.005) and the air temperature (Figure 10) suggesting that secondary photochemical reactions (gas-to-particle conversion), and oxidation of hydrocarbons and other organic precursors are the main ...

5) C4 hydrocarbons C4烃 1. The pressure -composition data of C4 hydrocarbons dissolved in mixture of morpholine and N-formylmorpholine at different temperatures are determined with a static method. 用静态法测定了不同温度下C4烃与混合吗啉溶剂体系(吗啉和N-甲酰吗啉的混合物)的压力-组成数据,并与...
The production mechanism of light nonmethane hydrocarbons (NMHC) in seawater was investigated during the North Atlantic atmospheric chemistry program (NATAC) in April and May 1991 in the European coastal seas and the North Atlantic. A significant alkene production occurred in the presence of light on...
