Comparison of different heat integration pressure swing distillation processes for separating isobutanol and p-xylene azeotrope.

Chemical process intensification has attracted extensive interest of scholars. Distillation, as a high energy consumption industry, is in urgent need of energy saving and CO emissions reduction by means of process intensification. In this paper, isobutanol and p-xylene azeotrope was separated by pressure swing distillation (PSD).

Research of CO-Soluble Surfactants for Enhanced Oil Recovery: Review and Outlook.

CO foam injection has been shown to be effective under reservoir conditions for enhanced oil recovery. However, its application requires a certain stability and surfactant absorbability on rock surface, and it is also associated with borehole corrosion in the presence of water. Adding surfactants to CO can enhance the interaction between CO and crude oil and control the CO mobility, thereby improving the performance of CO flooding.

Analysis of the electron transport properties in dye-sensitized solar cells using highly ordered TiO2 nanotubes and TiO2 nanoparticles.

This study uses TiO2 nanoparticles and highly ordered anatase TiO2 nanotubes (AOTnt) as thin film photoanodes for dye-sensitized solar cells (DSSCs). DSSCs are assembled by single-layer and double-layer films of photoanodes and their electron transfer performance is compared. TiO2 nanoparticles were fabricated by the sol-gel method, and AOTnts were grown on titanium foil.
