Speck resin is a mixture of the reaction products of volatile dicyclopentyl-ether diepoxide and ethylene glycol. Specif organic isocyanate is toluene diisocyanate. An epoxy resin hardening agent such as m-phenylenediamine can be added to the epoxy resin mixture. The modified epoxy resin thus ...

Toluene 1349 p-Xylene 508 【2.9】F=1000 kg/hr、P= 0.8 MPa、T=100℃含乙醇70 %w、水30 %w的物流与F=500 kg/hr、P= 0.6 MPa、T=70℃含正己烷60%、乙醇40 %w的物流在闪蒸器中混合并绝热闪蒸到P= 0.11 MPa。轻液相在汽相中的液沫夹带率为5%,重液相在汽相中的液沫夹带率为1%。求离开闪蒸器...
The success of proton exchange membrane water electrolysis (PEMWE) depends on active and robust electrocatalysts to facilitate oxygen evolution reaction (OER). Heteroatom-doped-RuOx has emerged as a promising electrocatalysts because heteroatoms suppress
The effect of CuO content on toluene adsorption/desorption was evaluated. We explored the reusability of AC and AC03 (CuO modified activated carbon (AC) with CuO loading 0.3wt.%) adsorbents via toluene adsorption/desorption cycle testing. We used quasi–first- and quasi–second-order models, ...
