Ammonia induction strategy for preparation of transition metal oxides / zeolite H₂S adsorbent

Blast furnace gas (BFG) is an important by-product energy for the iron and steel industry and has been widely used for heating and electricity generation. However, the undesirable contaminants, such as COS, CS2, and H2S, in BFG generate harmful environmental emissions. Due to the stringent ultra-low emission standards, the desulfurization of BFG is urgent for integrated steel plants. Compared with other desulfurization materials, zeolite-based adsorbents represent a viable option with low costs and long service life. However, the sulfur capacity of zeolite is relatively low and needs to improve. Impregnation of transition metal oxides onto zeolite is a common strategy to prepare H2S adsorbent. However, this method usually results in the agglomeration of metal particles during calcination, forming relatively large metal particles. The large metal particle may increase the gas diffusion resistance in adsorbent and inhibit the desulfurization performance. Therefore, minimizing the metal particles on zeolite with a high loading is the key to the preparation of an adsorbent with high sulfur capacity.

Petrified wood from the Willamette River, same trip as last post. Some excellent grain and optimistic agate cores in this bunch.

:O Could we see your laumontite? I knew opals were kept in water sometimes I didn’t know others did too! Ty for all your rock facts

Oh man, let me show you my absolutely stunning specimen of laumontite!!

This piece is about six inches long, and was collected from the upper peninsula of Michigan, right off the beach of Lake Superior. (My uncle found it!) As you can probably guess by its pastel colors, it belongs to the zeolite group of minerals.

While it may not look like much from a distance, up close it's an incredibly pretty specimen. Here are some closeups!

Look at those crystals!! Many of these brittle crystals have been broken by weathering, but they still display a great example of laumontite's crystal habit! Bladed sprays with very distinct faces.

The salmon pink coloration of this laumontite specimen is unique to Lake Superior! I believe it's due to the level of iron in the area.

Some of the crystals are growing intertwined with what appears to be calcite. (Though it may also be another zeolite mineral!) That's the shiny white stuff. It's a cool contrast to have the dull, sort of pearly pink laumontite crystals right next to the shiny white calcite.

Laumontite is a mineral which forms underwater, and has water as part of its crystal structure. If allowed to dry out completely, laumontite's crystal structure will lose its water molecules and decay into a powder called leonhardite. As such, it's a stone that requires some careful curation if you want to add it to your rock collection.

While the best way to store this rock would have been in a sealed container of water, I wanted to display it on a shelf with the rest of my collection, so I tried something a little risky! I soaked this specimen in a bath of heavily diluted Aileen's Tacky Glue, which is a craft glue that dries invisible and watertight. After soaking, I gently painted on multiple layers of the same diluted glue mixture, careful not to damage the brittle crystals. The idea was to create a watertight seal that prevented the stone from drying out. It sounds pretty wild, but this method is actually a common tactic for rockhounds trying to preserve laumontite!

As you can see, it worked really well! Despite being displayed in the open air on my shelf, the crystals remain beautifully defined. A difficult rock to care for, but so incredibly worth it!

Use Of Zeolite ( Molecular Sieve) For PSA Hydrogen Purification

When you use Molecular Sieve for PSA hydrogen purification there are low operating costs and the purification process of hydrogen is highly efficient and produces high purity and recovery rates for hydrogen as the end-product.

Molecular Sieve are commonly a type of crystalline microporous material, that contains unique absorbency characteristics that make them an ideal choice for the purification process of PSA hydrogen. Zeolites have a high rate of adsorbing capacity, and also exhibit selective separation techniques that help adsorb any impurities and contaminants from the hydrogen mixture effectively from the PSA system, thus resulting in a highly purified form of hydrogen as an end product.

Advanced nuclear magnetic resonance technique reveals precise structural, dynamical details in zeolites

Zeolites are widely used in many industries, yet their intrinsic catalytic nature is not completely understood, due to the complexity of the hydroxyl-aluminum moieties. Atomic-scale analysis of local environments for the hydroxyl species is essential for revealing the intrinsic catalytic activity of zeolites and guiding the design of high-performance catalysts. However, many unfavorable factors prohibit the elucidation of their fine structures such as low quantity, meta-stable property, structural similarity, hydrogen-bonding environment, and long-range disordered nature. Recently, a research team led by Prof. Hou Guangjin and Prof. Chen Kuizhi from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) unraveled the precise structure of complex hydroxyl groups in zeolites with a comprehensive set of self-developed coupling-edited 1H-17O solid-state nuclear magnetic resonance (NMR) methods. The study was published in the Journal of the American Chemical Society.

Found a jasp-agate the size of @kkatieclarkk when we made a quick stop along the Wilson River for our dogs to piss and shit and vomit. Also a cool little yellow jasper!

It’s all about the basalt ~ The Ellora Caves took 600 years to make. Chiseled out of black basalt, they are the largest monolithic structures in the world.

The outer surface has a seganitic structure not filled with silica. The interior is more seganite agate.
