Study the Effect of Various Parameters on the Synthesis of ZSM-5 Zeolite

Journal of Engineering, 2018
ZSM-5 zeolite was synthesis under hydrothermal conditions at 175oC. The synthesis parameters have been investigated to find optimum synthesis method. Firstly, the crystallization time has been investigated to find the optimum crystallization time.

Effect of SSZ‐13 Zeolite Loading and Synthesis Time on the CO2/N2 Separation Performance of PDMS Mixed Matrix Membranes

Journal of Applied Polymer Science, EarlyView.
Advantages of MMMs and the Robeson plot detailing improved performance of the 4d05% membrane. ABSTRACT Mixed matrix membranes were produced by incorporation of SSZ‐13 zeolites into polydimethylsiloxane (PDMS) to assess the effect of filler properties and concentration on the CO2/N2 separation efficiency compared to pure PDMS membranes.

Producing monoaromatic compounds from pyrolytic vapour of rice straw using H-ZSM-5/B2O3 catalyst

E3S Web of Conferences, 2018
The catalytic conversion of rice straw was done to produce mono aromatic compounds. The mixed catalyst of ZSM-5 and B2O3 was obtained through calcination of ZSM-5 and H3BO catalyst mixture.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension
