The hydrodesulfurization of benzothiophene (BT) and 2,3-dihydrobenzothiophene (DHBT) has been examined over a commercial cobalt molybdate on alumina and over an unsupported MoS2 catalyst promoted with Co. The results, in particular the appearance of

Crystalline MoS2 catalysts were impregnated with cobalt over the total composition range, and their catalytic activity in the hydrodesulfurization of thiophene tested in a microreactor at 400° and near atmospheric pressure. Three principal compositi

We have examined the effect of reducing MoS3 in hydrogen in the range 450–800 °C on the properties of the resulting MoS2 catalyst. The appearance of rhombohedral MoS2 at 800 °C is disputed. Instead, an 'overreduced' catalyst containing some Mo me

Calcium deficient hydroxyapatites were impregnated to varying degrees with fluoride in very dilute solutions of NaF at room temperature. Ca/P ratios were determined before and after fluoridation. Phosphate loss upon fluoridation was consistent with a

The adsorption and reactions of the four butenes on porous Vycor glass at room temperature have been studied by infrared spectroscopy. Initial adsorption was rapid and was found to perturb the surface hydroxyl groups of the glass. In the case of the

Infrared spectra of CO and CO2 adsorbed on chromia–alumina and on alumina surfaces have been determined. A band near 2200 cm−1 formed by CO on both surfaces at room temperature was due to a weak, non-activated sorption, but also contained a contr

Powders of silver catalyst of low calcium content and an 8.5% calcium in silver alloy were pelletized at different compacting stresses. The diffusibility of each pellet was measured, using hydrogen, and correlated with internal void volume, The surfa

The infrared spectra of CO and CO2 adsorbed on zinc oxide have been observed in the region 2–9 µ. The results show that CO does not exist as such on the surface at 155 °C, but is immediately oxidized to CO2. There is no evidence for carbonate for

From adsorption data and measurements of length changes of a porous glass rod, a qualitative description of the processes involved in the adsorption of water vapor is developed. Particular attention is devoted to the causes of the hysteresis loop. Th
