Coal Liquefaction Catalyst
118 KNCV Spring
Catalysis
Meeting
The Spring Meeting of the Catalysis of the Royal Dutch Chemical Society took place on 8th and 9th May in the Technical University of Delft. This is an annual event in which research workers from Industry, Llniversity and Technical University meet to present and discuss recent results. It is long-established practice to start each meeting with a presentation, from some-one working in industry, on the the more technical aspects of catalysis. This year's contribution was given by F.J. Langeveld, of Shell International, the subject being the production of ethylene oxide. The presentation covered both the technical aspects of the process and the more academic aspects, it being emphasised that there is still scope for academic work aimed at improving the selectivity of the reaction. A number of the papers on the first day were concerned with synthesis gas chemistry in one form or another. Examples were contributions from Verburg, Pelt and Scholten on supported liquid phase catalysts for hydroformylation; from Van den Berg,Freriks, Van Leuwen, Knoester, Versloot and Koortbeek on the role of formyl intermediates in carbonylation reactions; from Peels, Magnus, Van Welzen and Ponec on methanol synthesis over Rh and Pd catalysts; and from Morsink and De Groat on the use of EELS to study syn-gas conversion intermediates on Co(OOO1). Cerfontain and Moulijn discussed step-response experiments in potassium catalysed coal gasification while Van Broekhoven and Ponec discussed the effect of particle size on the formation of multiple bonds on a metal surface. Koningsberger, Van't Blik and Prins described their EXAFS results on the effects of the adsorption of hydrogen and CO on the structure of small supported rhodium particles while Noordermeer, Kok and Nieuwenhuys discussed the effects of effects of alloying on the adsorption of CO and hydrogen on Pd. In a somewhat different field, Meuldijk and Joosten dicussed the effect of solvent on the catalysed hydration of olefins by strong ion-exchangers. On the second day, the first group of papers were concerned with the properties of nickel catalysts: De Bokx, Wassenberg and Geus discussed the preparation of Ni-gamma alumina materials: De Korte, Doesburg Schaeper Section

and Van Reijen gave two papers on the interaction between NiO and alumina in coprecipitated catalysts and on the development of a thermostable methanation catalyst, respectively; and Wielers, Aaftink and Geus discussed the adsorption of CO and nitrogen on carbided nickel-silica catalysts. The next group of papers comprised: that by Bosch, Van Dam, Van Ommen and Gellings, on the reduction of NO with ammonia on vanadia-titania catalysts; one by Nobel and Van Geem on phosphorus-vanadium oxide catalysts for maleic anhydride production; and one from Vissers Mercx, De Beer and Prins, on cokicovered alumina as support for cobalt sulphide catalysts. This was followed by a group of contributions on ZSM-5 catalysts: the first, by Engelen, Wolthuisen and Van Hooff, was concerned with the reactions of dimethyl ether over these materials; a contribution by Van der Gaag, Jansen, Herlaar and Van Bekkum was concerned with template variation in the synthesis of the zeolite; and a paper by Scholle, Bakkum, Veeman, Frenken and Van der Velden was concerned with the application of magic-angle spinning NMR techniques to these and other materials. The final pair of papers dealt respectively with the use of XPS and electron microscopy to study Rh-Mnsilica catalysts for synthesis gas conversion (De Jong, Kuipers, Knoester, Glezer and Koortbeek) and Mossbauer and XPS research on supported bimetallic catalysts such as FeRu, FeRh, FePd, FeIr and FePt (Niemandsverdriet, Van Kaam, Flipse and Van der Kraan). The meeting was very successful and was very capably organised by a group of promovendi (Ph.D. workers) from the Technical University of Delft. Coal Liquefaction
Catalyst
A. Nishima and his colleagues of the National Chemical Laboratory for Industry (Japan) have reported (Chem.Soc. 1845(1983)) that a Japan, Chem.Lett., silicate sludge obtained from a geothermal power generation plant could be successfully used to prepare a catalyst for coal liquifaction. The sludge2haT a very high surface area (270-300 m3g_l), a large pore volume (0.87-2.62 cm g ) and a wide-range pore size distribution. It was found that the material prepared by supporting Moo3 on the sludge was superiour to a commerciallgavailable Ni-MO/A1203 catalyst.
