1 Chemical adsorption type.
2. No  need to activate, renew after using .
3  Low temperature except hydrogen, high activity except hydrogen.
4. Normal regeneration.
Application of Dehydrogenation catalysts 506HO-2
It is  applied in nitrogen, acetylene gas etc, and dhea inert gas purification processing CO2. As a highly oxygenated (0.5-2) % of nitrogen, oxygen by hydrogenation after removal of hydrogen, access to excess hydrogen excluding the high purity gases.
All catalysts are used for Sulfuric Acid, Phthalic Anhydride, Maleic Anhydride, Oxichlorination Fixed Bed, Styrene
A catalyst for the nonoxidative production of alkenylaromatics from alkylaromatics, wherein the catalyst is predominantly iron oxide, an alkali metal compound, copper oxide, cerium oxide and less than about 100 ppm of a source for a noble metal, such as palladium, platinum, ruthenium, rhenium, osmium, rhodium or iridium. Additional components of the catalyst may include compounds based on molybdenum, tungsten, calcium, magnesium, chromium and other such promoters.

How to use oxygen absorbers


Oxygen absorber is a small packet of material used to prolong the shelf life of food. They are used in food packaging to prevent food colour change, to stop oils in foods from becoming rancid, and also the growth of oxygen-using aerobic microorganisms such as fungi.
Oxygen absorbers are a key component to any long-term food storage plan.
Instructions of Oxygen absorber
1.Figure out the sizes and number of containers you will be filling with food.
2.Determine the appropriate size oxygen absorbers based on the size of the containers you are using. Mason jars usually require 50 cc oxygen absorbers. You will probably use 100cc or 250cc oxygen absorbers in No. 10 cans. Food grade pails that are 5-gallon and 6-gallon require at least 500cc oxygen absorbers.
3.Plan on using two to five oxygen absorbers per container, depending on the density of the food you are storing. More dense foods mean less void space in the container, which requires fewer oxygen absorbers. Less dense foods, such as whole oats, leave more void space and require more oxygen absorbers.
4.Calculate how many oxygen absorbers you will need for your food storage, and purchase the appropriate quantity. Oxygen absorbers need to be used within six months of manufacture. They cannot effectively be stored once the original package has been opened.
5.Prepare all your foods for storage. If you are using Mylar bags, insert them in your containers, and add the food to the containers. If you are not using Mylar bags, add the food directly to the container. Then, and only then, should you open your oxygen absorbers.
6.Add the appropriate number of oxygen absorbers to each container of food, and seal all containers within 15 minutes of adding the absorbers.

Features of Oxygen dehydrogenation catalysts 506HO-1

Features of Oxygen dehydrogenation catalysts 506HO-1
1 No  need to activate, perennial use, without regeneration.
2 Except hydrogen in low-temperature and high activity.
Application:It is applied for oxygen, air and oxygen in the atmosphere to except hydrogen purification.
Dehydrogenation is a chemical reaction that involves the elimination of hydrogen (H2). It is the reverse process of hydrogenation. Dehydrogenation reactions may be either large scale industrial processes or smaller scale laboratory procedures.

Where to search Effective from pure methane TJW?

Effective from pure methane TJW  is used for oxygen and oxygen gas methane dehydrogenation off from carbon monoxide. Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period and is emitted from a variety of natural and human-influenced sources. Human-influenced sources include landfills, natural gas and petroleum systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial process. It is mainly used for chromatographic spectra, energy, such as carrier gas purification, used in the chemical, electronic, metallurgy, medicine and food, aerospace and other research field of anaerobic operation and ultra pure gas preparation.
