Cold Acid A process for polymerizing isobutene, mainly into dimers and trimers, for making high-octane gasoline blending components. It is catalyzed by 60 to 70 percent sulfuric acid at 25 to 35°C. Developed by the Shell Companies. See also Hot Acid. 

A product of the Shell Company under the code O.S. 2046 (OO dimethyl 2 Carbomethoxy-l-methylvinyl phosphate) is a water soluble insecticide which does not appear to be metabolized. Its oral toxicity to rats is 4 mg./kg. 

Polymerization with Sulfuric Acid. In the early 1930 s development work on sulfuric acid-catalyzed polymerization was undertaken by a number of research organizations. The most widely used process is that developed by the Shell companies (IS). 

The electron capture detector is the result of a series of developments which were initiated in 1951 by D. J. Pompeo and J. W. Otvos (14) of the Shell Company s development laboratory in California. The device they invented was a beta-ray ionization cross-section detector (Section 5.8). Deal et al. (15) at the Shell laboratory in California and Boer (16) in Amsterdam modified the detector, used originally to monitor effluents of a large scale plant process, for applications in GC. From the limited success of the detector. Lovelock (17) produced the beta-ray argon detector in 1958 (Section 5.8). This modification substituted argon as the carrier gas and placed a potential of 1000 V across the electrodes. Argon passing between the electrodes absorbed radiation and formed a metastable species with energy (11.6 eV) sufficient to ionize most substances. Proposed mechanisms for this process are ...

This model represents one of the first modeling approaches used to describe large industrial beds that has been fully documented and discussed in the open literature. The model was adopted by the Shell company designing a fluidized bed reactor for their solid catalyzed hydrogen chloride oxygen process. However, the model has many of the same limitations as the Davidson-Harrison model because is was developed before the importance of bubble clouds and wakes were realized. 

Since the late 1940s Royal Dutch/Shell companies have been carrying out research and development work on hydrocarbon synthesis for the conversion of various raw materials, such as coal and natural gas, into liquid transportation fuels. When crude from the Middle East became increasingly available, some reduction in this work occurred, but interest revived in the early 1970s.

The preceding work was carried out with the assistance of a postdoctoral fellowship kindly provided to one of us (K.T.) by the Shell Fellowship Committee of the Shell Companies Foundation, Inc. It also forms part of a program on Solid State Properties of Catalytic Activity supported by the Office of Naval Research N6onr-27018. For this support we wish to express our appreciation and thanks. 

We collected Fox and a young British code officer from the legation, named Arthur, who wanted to go to Damascus, and our next stop was the only functioning gas station in town, operated by the Shell Company. As we approached it, my heart sank. There were at least fifty cars lined up, two abreast, waiting their turn. And it was already 1 40. 

The dlglycldyl ether of blsphenol A (DGEBA) was obtained from the Shell Company (EPON 828) and was cured with 2% dimethyl-benzylamlne (BDMA, Eastman Kodak Coiq)any). Samples were thoroughly mixed prior to curing and were cured at 125°C and 160°C for various lengths of time.

Block copolymers can also be hydrogenated to produce unique products. Hydrogenated triblock copolymers of poly(styrene-co-butadiene-co-styrene) (SBS) are commercially available from the Shell Company under the trade name Kraton G. The middle block is usually a mixed microstructure of poly( 1,2-butadiene) and poly( 1,4-butadiene) units. The resulting product is a hydrogenated unsaturated polymer, which exhibits greater thermal and oxidative properties than the parent SBS triblock. 

Using living polymerizations, the Shell Company was able to commercialize several poly(styrene-co-butadiene) and poly(styrene-co-isoprene) block copolymers known in the industry as Kraton 1101 and Kraton G. These block copolymers have found many uses in the shoe sole and adhesive industries. The physical properties were dependent on the macrostructure and microstructure of these block copolymers. 

The first gas-phase polymerization was first commercialized in Wesseling, Germany by ROW Co. in a joint venture with BASF and Shell companies in 1969. This facility employed the Novolen process for propylene polymerization in the gas phase. UCC and Sumitomo companies later developed fluidized-bed processes for the gas-phase polymerization of propylene. The advantages of this process are its high-effidency catalysis, elimination of residual removal, and elimination of evaporation or centrifugal separation. Its polymer product can be used in almost all applications [12,13,71,72]. 

Currently, there are three large industrial complexes one factory Shell Company in Malaysia a series of plants operated by Sasol and one factory of PetroSA, both in South. The first one, despite the small scale of 15,000 barrels per day, it is economically viable because their production is destined for food-grade paraffin. In South Africa, the PetroSA industrial plant has a capacity of 36,000 barrels per day, while the two Sasol plants produce more than 100,000 barrels per day (bpd).
