Methanation Catalyst

It has a strong photo catalytic oxidation-reduction capacity, high chemical stability, non-toxic, forbidden band gap of 3.0 ev, being uv (under 380 nm) excited scope. In the effect of sunlight or ultraviolet light , the electronic (e-) on the valence band can be excited transition to the conduction band and brought a corresponding hole (h +) on the valence band. And then h + e- and h2o adsorbed on the surface of tio2 play a role and generate oh, o2-high active group, active oxygen and hydroxyl radical with high oxidation which can make harmful organics, pollutants odor, bacteria etc. Such as formaldehyde, amino methane, benzene, xylene, ammonia, organic tvoc, and so on oxidative decompose into harmless co2 and h2o. Giving full expression to the nano tio2 photo catalyst for antibacterial, sterilization, disinfections, remove pollutants, hydrophilic, and the self-cleaning properties, it is an ideal environmental protection products.

Product standards:
Appearance: white powder
Tio2 content: 90%
Crystal: anatase
Sem average size: 20 nm
Ph value: acidic
Photo catalytic efficiency: 60%
Moisture: 1%.

Gas solding iron catalyst is placed in the combustion chamber of the gas iron, which accelerate combustion and meet temperature and environmental requiremnet.

It is easy to achieve and start-up and robust enough to withstand washing in the event of external contamionation. Especially can be suit for using under high pressure, high space velocity and lowtemperature conditions.

The catalyst is used in the methanation process of ammonia and hydroge plants.
Carbon monoxide and carbon dioxide react with hydrogen from a hydrogen-enriched process gas through a methanation reaction to produce inert gas methane and water.

Iron oxide desulfurization agent because of its high sulfur content, low price, can be recycled at room temperature and so on, and is welcomed by users. But there are also poor strength, meet, desulfurization gouache precision (1ppm) and other shortcomings, affecting its industrial application.

In view of the above situation, our company technical personnel after several years of painstaking research, developed a series of hyf new type of iron oxide desulfurization agent, which is characterized by:

1, high desulfurization accuracy: imported h2si1000ppm, the export of 0.05ppm h2s, than the average fe2o3 of the desulfurization accuracy (1ppm) 20 times higher;

2, fast response: the use of 1000-20000h-1 fe2o3 to be higher than ordinary airspeed 3 - 6 times.

3, work (through) sulfur capacity: under the conditions of 1 and 2, a one-time fine removal of h2s sulfur content of o2 is
20% - 3, 15 - 6 times the average fe2o3 desulfurization agent.

4, good strength, good water resistance. Boiled 2h or soak for 30 days without powder, strength unchanged.

5, suitable for a wide range of temperature, 90 - 5

6, can be used in the absence of o2 or high co2 conditions. H2s sulfur content 12 - 15%.

The application of desulfurization of natural gas, water gas and semi water gas, air gas, coke oven gas, gas, and co2 transform anger, food co2, steel raw material gas, methane gas, petrochemical and other gases finishing off h2s, and can also be matched with 504 h2s+co2 hydrolysis catalyst reaches more than 0.06ppm, compensate for the lack of active carbon desulfurization the agent, so that the iron oxide desulfurizer new technology has been widely used.

Resistant to the ball of fire
Refractory ball is a kind of refractory material with a very wide range of applications. Refractory ceramic ball is made of industrial alumina and refractory kaolin as the main raw material, which is made by scientific formula, shaping and high temperature sintering.
Refractory ball has high mechanical strength, long service cycle, high temperature resistance, oxidation resistance, wear resistance, strong acid and alkali chemical corrosion, excellent resistance to quench heat and very low chemical activity.
Fire resistant classification
1, according to the aluminum content
Ordinary refractory ball: suitable for converter sulfuric acid and the chemical fertilizer industry and transform furnace
High aluminum refractory ball: high aluminum resistance to the fire, the application of urea, steel and other industries, such as hot blast furnace, heating transformation furnace and other equipment.
2, by type
Refractory ball: aluminum content 45-90, 10-70 silicon content, iron content is less than 1.
Corundum refractory ball: aluminum content 90-98, 0.5-5.0 silicon content, iron content is less than 0.5.
Low silicon aluminum refractory ball: the contents of 90-98, silicon content is less than 0.3, iron content is less than 1.
