Monometallic doping has proved its superiority in improving either permselectivity or H2 permeability of organosilica membranes for H2/CO2 separation,but it is still challenging to break the trade-off effect.Herein,we report a series of Pd-Nb bimetallic d
Bubble/Slurry bubble column reactors (BCR/SBCR) are intensively used as multiphase reactors for a wide range of application in the chemical,biochemical and petrochemical industries.Most of these applica-tions involve complicate gas-liquid/gas-liquid-solid
Opposed multi-burner (OMB) gasification technology is the first large-scale gasification technology developed in China with completely independent intellectual property rights.It has been widely used around the world,involving synthetic ammonia,methanol,e
Hydroformylation of formaldehyde to glycolaldehyde (GA),as a vital reaction in both direct and indirect process of syngas to ethylene glycol (EG),shows great advantages in the aspects of the process complex-ity and clean production.The hydroformylation of
A set of metal nanoparticle-decorated titanium dioxide (Mx/TiO2;where x is the percent by mass,%)photocatalysts was prepared via the sol-immobilization in order to enhance the simultaneous hydrogen (H2)production and pollutant reduction from real biodiese
Due to the high salt content of coal chemical wastewater,pipeline fouling often occurs during wastew-ater treatment.Fouling will cause the diameter of the pipe to shrink or even block,which is not conducive to the safe and stable operation of the wastewat
The coronavirus disease 2019 (COVID-19) pandemic has led to a great demand on the personal protection products such as reusable masks.As a key raw material for masks,meltblown fabrics play an important role in rejection of aerosols.However,the electrostat
The simultaneous CO2 capture and heat storage performances of the modified carbide slag with by-product of biodiesel were investigated in the process coupled calcium looping and CaO/Ca(OH)2 thermo-chemical heat storage using air as the heat transfer fluid
Five kinds of BZSM-5 molecular sieve with different Si/B ratio and a SiZSM-5 molecular sieve were pre-pared by hydrothermal synthesis method followed by acid exchange and pelletization.The samples were characterized by XRD,SEM,FT-IR,ICP,low temperature N2
The characteristics of the energy structure of rich coal,less oil and less gas,coupling with a high external dependence on oil and natural gas and the emphasis on the efficient and clean utilisation of coal,have brought opportunities for coal chemical ind
