|
| Some of the most commonly used chelants in detergent industry are phosphates, EDTA, sodium citrate and zeolite compounds. |
|
| Moreover, these Na-treated zeolite catalysts still exhibit acceptable endurability and good catalysis in the transesterification reaction after nine consecutive cycles. |

|
| Comparison is made with assemblages at Arlington Quarry on North Mountain, where the dominant zeolite minerals are heulandite and stilbite. |
|
| The operating principle of the apparatus is based on the air passing through zeolite, a porous mineral material whose cavities, with a size of the order of the nanometer, separate the molecules of nitrogen and oxygen. |
|
| Taylor and Harold C. Urey, who used a zeolite. |
|
| Meanwhile, further field trials of warm mixes with zeolite and waxes were carried out in April 2009 on a public Belgian road, in cooperation with the Flemish Road Administration. |
|
| The key advantages of citrates in detergent formulations are its biodegradability and the ease of its processing, particularly in formulations containing zeolite. |
|
| Whereas zeolite and wax can be added to an asphalt mix using conventional asphalt plant, preparation of foamed bitumen is more complicated and field testing correspondingly more complex. |
|
| A porous material called zeolite separates the various gases in the air. |
|
| During the last 20 years, legislation has restricted the use of phosphates in detergents which has boosted the demand for zeolite as a non-phosphate builder, to almost 1million tons. |
|
| Catalytic decomposition, where NO is reduced over a copper substituted zeolite catalyst, initially seemed promising but has proved difficult to engineer and extremely sensitive to sulphur poisoning. |
|
| Six years ago, another group used X-ray spectroscopy to pinpoint the locations of metal ions bound to a zeolite called faujasite. |
