Dry reduced nickel catalyst protected by fat is the most common catalyst for the hydrogenation of fatty acids. The composition of this type of catalyst is about 25% nickel, 25% inert carrier, and 50% soHd fat. Manufacturers of this catalyst include Calsicat (Mallinckrodt), Harshaw (Engelhard), United Catalysts (Sud Chemie), and Unichema. Other catalysts that stiH have some place in fatty acid hydrogenation are so-called wet reduced nickel catalysts (formate catalysts), Raney nickel catalysts, and precious metal catalysts, primarily palladium on carbon. The spent nickel catalysts are usually sent to a broker who seUs them for recovery of nickel value. Spent palladium catalysts are usually returned to the catalyst suppHer for credit of palladium value.

Peracidox A process for removing sulfur dioxide from the tail gases from sulfuric acid plants by absorption in peroxomonosulfuric acid (Caro s acid). The peroxomonosulfuric acid is generated on-site by the electrolytic oxidation of sulfuric acid. Developed by Lurgi and Sud-Chemie and first operated in 1972. 

Kim and Thompson—site blocking by formates/carbonates over Au/ceria catalysts linked to deactivation. Kim and Thompson437 reported on the deactivation of Au/ceria catalysts. The ceria was prepared by the decomposition of cerium carbonate (BET SA ceria calcined at 400 °C = 203 m2/g) or obtained from Rhodia (BET SA ceria calcined at 400 °C = 155 m2/g). Au was added by precipitation of HAuC14, resulting in a particle distribution between 1 and 10 nm, with the majority of clusters between 2 and 7 nm, as examined by HR-TEM. The experimental catalyst was tested with respect to the Sud-Chemie water-gas shift catalysts, consisting of Cu-Zn-Al with surface area 60 m2/g, and results are reported in Table 87. 

The earliest industrial zeolitic isomerization process was the Hysomer process, formerly offered for license by Shell. Currently UOP offers a zeolite- and Pt-con-taining catalyst HS-10 in the fixed-bed UOP TIP process [3]. A similar catalyst Hysopar was introduced by Sud-Chemie [22] in the CKS Isom process (Cepsa-Kellogg-Sud Chemie). Recently there were reports of IMP-02 and CI-50 commercial catalysts from China [23] and Russia [24]. 

The following catalysts were used for reactivity tests (a) H-mordenite zeolite, H-MOR40, shaped in extrudates, supplied by Sud-Chemie AG, and having Si02/Al203 ratio equal to 40. (b) AIF3, supplied by Aldrich, (c) AFP/0, prepared following the...

Reuse et al. [24] applied a reactor carrying micro structured plates for methanol steam reforming over commercial copper-based low-temperature water-gas shift catalyst from Sud-Chemie. The reactor took up 20 plates made of FeCrAl alloy of size 20 mm x 20 mm x 0.2 mm. The channel size was 200 pm x 100 pm (Figure 2.5). The catalyst was conditioned by oxygen and hydrogen treatment.

Na/FAU (lg), obtained from Sud Chemie (CBV 100), was stirred at room temperature for 24 h in a 1 M copper(II) chloride solution. The solid was filtered, washed repeatedly with water until obtaining a neutral filtrate, dried overnight at 353 K and calcined under flowing dry air (250 mL.min 1) at 723 K for 6 hours. 

In this paper three zeolite catalysts from Sud-Chemie AG (USY-zeolite Si/Al 2.3-2.5, H-ZSM-5 Si/Al 15 and H-mordenite Si/Al 10) have been investigated in a gradientless reactor under supercritical conditions using the disproportionation of ethylbenzene (EBD) as test reaction and butane or pentane as inert. A previous publication reported investigations on those three catalysts at normal pressure and the details about the geometry of the three zeolites [6]. 

CKS ISOM CEPSA KBR Sud-Chemie HYSOPAR HYSOPAR-SA (proprietary) ... 

The HYSOPAR catalyst has been developed by CEPSA on a laboratory scale. The modification of the laboratory procedure to allow commercial scale production was successfully completed by SUD-CHEMIE who exclusively manufacture this catalyst. HYSOPAR is a strongly acidic mordenite based catalyst. Its most striking feature is the extreme tolerance for sulfur and other feed contaminants. 

An Al3+-exchanged montmorillonite, for example, is as active as concentrated sulfuric acid in promoting acid-catalyzed reactions. Sulfuric acid treatment of natural montmorillonite similarly affords the much more active and widely used acid catalyst known as K-10 or KSF (from Sud-Chemie or Fluka, respectively).

Application Technology for dehydrogenation of propane (or isobutane) to make high-purity propylene (or isobutylene). The CATOFIN process uses specially formulated proprietary catalyst from Sud-Chemie. 

EnviNOx Two related processes for removing N20 and NOx from the tailgases from nitric acid manufacture by the Ostwald process. Both variants use two beds of two zeolite catalysts modified with iron. The first variant is for gases hotter than 425°C and involves injecting ammonia between the beds. The second variant, for gases cooler than 425°C, injects ammonia before the first bed and a volatile hydrocarbon between the beds. Developed by Uhde in association with Agrolinz Melamine International. The first variant was installed in Linz, Austria, in 2003. The second variant was installed in Egypt in 2007. The catalysts are supplied by Sud-Chemie.
