Rare Earth Modified Molecular Sieve De

Technical index of rare earth modified molecular sieve De-NOx catalyst has been completely beyond the traditional V2O5-WO3/TiO2 system. At the same time, we have successfully developed the preparation technology of the monolithic catalyst, which can realize the scale production of the molecular sieve De-NOx catalyst.

catalyst have been highly sought after by many refiners. A more detailed discus-sion on the development of RE-free FCC catalysts is discussed in Vol. II, No. 3 of Refinery Operations: "The Development of Rare-Earth Free FCC Catalysts," by Colin Baillie and1 n

Catalyst for the VGO market providing maximum accessibility and maximum middle distillate production. Granite™ The Granite™ technology platform is based on a novel matrix/binder system, which expands the catalyst formulation window and enables refiners to maximize their profitability

The 3-way catalyst consists of a mixture of precious metals, zirconium and rare earth (mostly cerium) wash coated into a brick inserted in the vehicle's exhaust pipe. This market segment has been growing steadily above 5% per annum in the past 10 years and is expected to continue to grow as emission control regulations around the world are strengthened.

Current status and perspectives of rare earth catalytic

2014/8/1Rare earth elements possess 4f orbitals without full electron occupancy and lanthanide contraction. This characteristic results in their unique catalytic performance when they are used as active components or as catalyst supports. Research into and the

Pursuing a better hydrogenation performance and stereoselectivity, we successfully developed a rare earth hydride supported ruthenium catalyst Ru/YH 3 for the hydrogenation of N-heterocycles, especially N-ethylcarbazole (NEC), the most promising LOHC.

Neodymium(III) chloride or neodymium trichloride is a chemical compound of neodymium and chlorine with the formula NdCl 3.This anhydrous compound is a mauve-colored solid that rapidly absorbs water on exposure to air to form a purple-colored hexahydrate, NdCl 3 6H 2 O. Neodymium(III) chloride is produced from minerals monazite and bastnsite using a complex multistage extraction process.

Rare earth metals or rare earth elements (REEs) are a relatively abundant group of seventeen elements found in the periodic table. Out of the seventeen, fifteen elements comprise the lanthanide series found between atomic number 57 and 71.

2017/7/1We have found that the interaction between the heteroatom in an α-olefin and the rare-earth metal atom in a catalyst not only can significantly raise the olefin polymerization activity but also can enable the efficient copolymerization of the heteroatom-containing α

2018/2/1Rare earth doping is an effective way to improve the performance of the Ru/MgAl-LDO catalysts for ammonia synthesis. Abstract A series of MgAl-layered double oxides (LDO) doped with different rare-earth elements (Y, La, and Ce) were synthesized by the calcination of Mg–Al layered double hydroxides, and Ru, which were used to prepare ammonia synthesis catalysts.

The rare-earth element concentrations are not typically affected by sea and river waters, as rare-earth elements are insoluble and thus have very low concentrations in these fluids. As a result, when a sediment is transported, rare-earth element concentrations are unaffected by the fluid and instead the rock retains the rare-earth element concentration from its source.

Rare earth is used to stabilize FCC catalyst zeolite in order to provide high FCC catalyst activity, liquid selectivities and superior coke selectivity. Removing rare earth from FCC catalyst will provide relief in catalyst expenses; however, it is not an economical solution in most FCC operations due to a lower activity and product value.

Abstract The recovery of rare earth metals from secondary sources has attracted much attention due to their ever expanding demand in the high-tech industry. The studies reported here focus on the hydrometallurgical recovery of lanthanum and cerium from spent
