402 Fischer-Tropsch

Catalysis

recent Three articles, all in J. Chem. Sac. Chem. Commun., deal with Fischer-Tropsch catalysts which exhibit deviations from the usual AndersonSchulz-Flory (ASF) statistics. Snel (1986, p. 653) describes catalysts prepared by the partial decomposition of iron complexes; within this family, an Fe-Ca sample exhibited a non-ASF distribution with about 65 mass% hydrocarbon in the C3-C5 range. Within this range, alkenes were present to the extent of ca 80%. Using a cobalt-&O combination, van der Riet, Hutchings and Copperthwaite (1986, p. 798) report sustained high C selectivities from the hydrogenation OS CO. Much of this C product is propene. Shape selective ef s ects in Co-Nay zeolites are considered to be responsible for the truncated ASF distributions found by Ungar and Baird (1986, p. 643). The cobalL was introduced into the zeolite as Co(CO)3N0.

Prof. Bruce Gates, H. Rodney Sharp Professor of Chemical Engineering and Director of the Center for Catalytic Science and Technology at the University of Delaware, has received the Catalysis Club of Philadelphia Award. The award was given in recognition of Gates' many contributions to both applied and fundamental catalysis; he has published over 120 technical papers and patents and his supported metal catalysts is work on widely known and appreciated. Dr. Anthony J. Perrottta, Fellow at the Aluminium Company of America Alcoa Laboratories has been awarded the Pittsburg-Cleveland 1986 Award in Catalysis. Sponsored by Nalco Chemical Company, the award recognises Dr. Perrotta's work in clays oxidation the areas of zeolites, hydrocracking, catalysts, coal liquecoke formation and crystalfaction, lography. Before joining Alcoa in 1985, he wor!ced with the Gulf Oil Corporation.

Metals

from Methanol

'The mechanism of the formation of hydrocarbons from methanol continues to attract much interest and controversy surrounds the various suggestions which have been put forward. Olah and co-workers (J. Chem. Sot. Chem. Comaun., 1986, re-emphasize the oxonium ylide P.9) mechanism of ethylene formation, while evidence against this route is presented by Hunter and Hutchings (J. Chem. Sot. Chem. Commun., 1985, p.886, 1643). Carbon-carbon bond formation via radicals is proposed by Choukroun et al. (J. Chem. Sot. Chem. Commun., 1986, p.6) and the additional argument as to whether or not ethylene is a primary product in the conversion process is addressed by Dessau (J. Catalysis 99 (1986) 111). He concludes that ethylene results from secondary reactions of the primary prcduct olefins, propylene and butenes.

Iii11 be held This conference in Brussels from 14th-18th June, 1987 under the auspices of the International Precious Metals Institute. A call for papers has been made on topics covering all aspects of the production and use of precious metals, including precious metals in catalysis: production use and recycling of precious metal catalysts, including exhaust catalysts: fuel cell technology; and legal aspects of automotive emission control and its impact on catalyst consumption in the petrochemical industry. Poster sessions will focus on specific aspects of major research achievements. The proceedings will be published. Further details can be obtained from the Technical Programme Chairman, Mr. G. Vermeylen, whose address is given the Calendar of Forthcoming Events.
