Fe203 and 55 weight % silica, as support, with 1% sodium silicate as a binder. In the preliminary work fly ash was considered as a support material but the maximum amount of iron oxide which could be incorporated with it was 25 weight % Based on this and the other criteria discussed above, the iron oxide-silica composition was found to be the most suitable sorbent for bulk H2S removal,... 

As it was stated in [1] the blocking of zeolite crystals at low zeolite loadings is caused by formation of amorphous sodium silicate inside the support pores at the initid crystallization step. This silicate transforms to zeolite crystals during... 

Metal-support interaction was observed in two nickel-silica catalysts, but they were prepared either by precipitating a complex carbonate from nickel nitrate solution containing Si02 as a slurry or co-precipitating the carbonate from a solution of nickel nitrate and sodium silicate. The similar spectra from the unreduced catalysts resembled in shape and binding energy a NiSi03 standard and were quite distinct from NiO. The interaction was... 

Grouting was done along the entire tunnel length, both to provide structural support and reduce water inflow. In the land portions of the tunnel, cement was the main grouting material. Under the sea, sodium silicate-based grout was the primary material. Most of the work was done at short gel times, 10 min or less. Colloidal cement was used with the silicate for catalysis, in part of the tunnel. 

The transformation takes place in the gas phase, in the presence of a supported mercuric chloride base catalyst in general, at a temperature between 100 and 170°C, and a pressure of about 03.106 Pa absolute. The support is activated charcoal, but this can be replaced by graphite, aluminum and sodium silicate etc.
