New Engelhard
Catalyst
Plant In Ter-
neuzen September saw the opening in Terneuzen (The Netherlands) by Engelhard of a new plant and laboratory for the production of FCC catalysts for the cracking of crude oil. Claimed to be the most advanced plant of its kind in the world, this is the first FCC plant of Engelhard outside the U.S.; it will supply catalysts to refineries in Europe, Africa and the Middle East. It will produce the newest Engelhard catalysts, Precision and Octidyne Extra, introduced at the beginning of 1989. Catalyst Consuttants This organisation, based in Spring House, Pennsylvania, U.S.A., have reorganised to market their services under The Catalyst Group which will consist of four companies: Catalyst Consultants, Inc., Catalyst Consultants Europe Ltd., Environmental Catalyst Consultants, and Catalyst Consultants Publishing Company (which will take over publishing of The Catalyst Review).

Shape selective synthesis Styrene from n-Octane
of
In a recently issued U.S. Patent assigned to the Mobil Oil Corporation, R.M. Dessau and E.W. Valyocsik (U.S. Patent 4 922 942) described the use of an indium (0.01 to 20 wt.-%)-containing ZSM-5 catalyst for the shape-selective synthesis of styrenefrom n-octane. Withinthe specifications of the patent they provide and interesting table Fable A) which describes hydrocarbon conversion and benzene/toluene seleotiviiies for platinum-coated boron- or

indium-containing ZSM-5 catalysts. With n-heptane, both boron-treated or SilZSM-5 gave mixtures of benzene and toluene on dehydrogenation. However, the indium ZSM-5 gives 97% selectivll to toluene at 99% conversion. Example 1 within the patent (containing 1.85% platinum on In/ZSM5) reports a 99.4% conversion at 550°C of n-octane to yield 94.3% styrene.
Carbon Dioxide and Methane as Feedstocks H. Arakawa, in Technology Japan, (21(19&3)31), provides a review entitled “Development Trends of Direct Utilization of Methane and Carbon Dioxide as Feedstocks for Chemicals” which focuses on selective methane oxidation as well as selective CO:! reduction. The review is targeted at utilizing C, chemistry in anticipation of any future worldwide oil crisis. He reports that the consensus is “that C, chemical industry will eventually replace the petrochemical industry in the future”. The paper reviews the solid acid catalyst processes which might eventually lead to improved catalysts to fix methane and COB. NOx Abatement M. Grove and W. Sturm (Ceramic Engineering Science Proceedings, 10(1999)325) have described the CER-NO,” processfor the selective catalytic reduction of NO, as applied particularly to glass metting furnaces which generate NO,. The CERNOx” process is a turnkey NO, (SCR) abatement process which uses a ceramic, molecular sieve catalyst honeycomb module. The article claims that unlike metal type SCR catalysts, the molecular sieve catalysts are virtually immune to poisoning, plugging and masking. They suggest that high electrostatic forces within the pores reduces the reaction potential of NO, and
