Reaction of drilled-cores from the Janggi basin with CO2-saturated brine from subcritical to supercritical condition of CO2: Implications on sequestration of dissolved CO2

According to compressor working conditions and compressor lubrication performance requirements in this paper. It use a polyether and dioctyl sebacate as the base oil, and adding a variety of functions of composite additive deployment, Develop a kind of a compressor oil used on compressing and filling sulphur dioxide (SO2) in the supercritical condition. Experiments show that the developed compressor oil not only meets the performance requirements of compress and filling SO2 in supercritical condition, but also has a very strong adaptability condition.

Plating Solution

Electroplating using a Ni-plating solution/CO2 macroemulsion was carried out at a supercritical condition. This method is that the Ni+2 ions in the macroemulsion using a surfactant have been deposited onto Cu. For forming the macroemulsion, we synthesized the fluorocarbonhydrocarbon surfactants, that is, sodium salt of bis (2,2,3,3,4,4,5,5-octafluoro-1-pentanol) sulfosuccinate with both ‘CO2 philic’ chains and the ‘hydrophilic' head group. The Cu plate, screw and chip as complicated shaped metals were plated by using this method. And the plated ware performed by this method was compared with that performed by the conventional method (electroplating at 1atm) to evaluate the effectiveness of the effective plating process.

Hydrogenation Of Co

Hydrogenation of CO 2 to alcohols is of great importance, especially when producing higher alcohols. In this work, we synthesized heterogeneous PtRu/Fe 2 O 3 , in which the Pt and Ru bimetallic catalysts were supported on Fe 2 O 3 . The catalyst was used to catalyse CO 2 hydrogenation to alcohols. It was demonstrated that the activity and selectivity could be tuned by the bimetallic composition, and the catalyst with a Pt to Ru molar ratio of 1:2 (Pt 1 Ru 2 /Fe 2 O 3 ) had high activity and selectivity at 200°C, which is very low for heterogeneous hydrogenation of CO 2 to produce higher alcohols. The conversion and the selectivity increased with increasing pressures of CO 2 and/or H 2 . The catalyst could be reused at least five times without any obvious change in activity or selectivity.
