The FCC process is the most common conversion unit in use today. As such, it is important to determine the performance of an FCC when feeding hydrotreated shale oil. The two 650° F+ feeds shown in Table VI were evaluated in an FCC pilot plant operating in a fixed fluidized-bed mode. The catalyst was withdrawn from an operating commercial FCC unit. It is a zeolite catalyst, CBZ-1, produced by Davison Chemical Division of W. R. Grace and Company and is moderately active as well as contaminated with metals. 

The Chemical Division could not have performed its authorized function of stimulating defense production had it not been for industry and commodity statistics. Personnel had to know current production, consumption, and stocks of chemicals and related products. It had to be informed of existing demand and possible future demand for hundreds of inorganic and organic chemicals. Because of its functions concerned with processing applications for rapid tax amortization and loan assistance, the division also kept informed of planned chemical expansions. 

Chemicals is organised in three divisions Polymers, Performance Chemicals and Intermediates, and products include emulsions (adhesives/coatings), polyvinyl alcohol, amines, surfactants and polyurethanes.

They also have a substantial know-how about which type of catalyst is the most suitable for a specific problem. Our experience has shown that it is of advantage to search for or optimize a suitable catalyst in close collaboration with the catalyst suppliers. This is especially true for the development of technical processes and/or when the development team has little hydrogenation experience. Catalyst screening and development should always be performed with specified catalysts that can be supplied in technical quantities when needed. For laboratory use, Fluka and Aldrich Inorganics offer a wide variety of hydrogenation catalysts that are adequately suited for preparative purposes, although the catalyst manufacturer and the exact type of catalyst is not usually specified. 

Many of Crompton s additive products, which altogether account for 58% of the company s sales, are used in the PVC industry. Others are targeted at the compounders of engineered thermoplastics, polyolefins, polyamides, polyester and EPDM. Annual sales are around US 2.2 billion. In the last two or three years strong efforts have been made to raise prices, with mixed results, and this may have contributed to a loss of sales volume. The company s chemical activities are being reorganised into one business containing the divisions previously known as Plastics and Petroleimi Additives and Performance Chemicals and Elastomers.

Rheobay Electrorheological Fluid. (Provisional product information TP AI 3566. Miles Industrial Chemical Division, USA.) Although the effect of a change of temperature will be evidenced in the above properties (and may affect the settlement rate of the solid, which can only be matched perfectly with the base fluid at one temperature), none is more significant than its effect on current density J. Here, a small increase in temperature can raise the current consmnption considerably, and vice versa. This is a major problem area of ERF. Certainly this factor alone is sufficient justification for the use of a simple approach to the initial characterisation, fluid comparability problem and design procedures. Different temperatures can change slopes of the r, 7-characteristic increased temperature can often increase current to that for the optimmn (however small it is) and Te performance and/or give a level Te f j) characteristic or thereabouts.

P(ANi) has been marketed for some time as a chemically polymerized, proprietary-sulfonate-doped CP under the tradename Versicon, Originally produced by the Allied Signal Corp. based in Morristown, NJ, USA, the product line was taken over in the mid-1990 s by the High Performance Materials division of Monsanto Co., St. Louis, MO, USA. 

Originally, the Al used in Minol II was in the form of a fine powder. It was shown later that such a high degree of sub-division was unnecessary, and that good performance could also be achieved with Al filings, shavings and flakes. The latter form is particularly advantageous in that the smaller total surface area of Al present in the mixt minimizes its reactivity in Minol and enhances the chemical stability of the compn (Ref 28)...
