Abstract: A process for the selective formation of ethanol which comprises contacting methanol, hydrogen and carbon monoxide with a catalyst system comprising cobalt acetylacetonate, a tertiary organo Group V A compound of the periodic Table, a first promoter comprising an iodine compound and a second promoter comprising a ruthenium compound.

Abstract: A process for preparing a catalyst which involves coating a support with a first solution containing a platinum or palladium salt and a rhodium salt, calcining, further coating the calcined support with a second solution containing a salt of ruthenium and an oxide, salt or acid of phosphorus and then further calcining.

Abstract: The conversion of carbon monoxide and hydrogen to produce a mixture of low molecular weight hydrocarbons which, on a methane-free basis, contain a predominance of C.sub.2 -C.sub.6 paraffins is achieved using as the catalyst a rare earth metal promoted layered complex metal silicate composition characterized as having repeating units of the structural formula[(1-x)Ni.sup.a + xRu.sup.6 ].sub.n (OH).sub.4 Si.sub.2 O.sub.5.wH.sub.2 Owhere x is a number from 0 to 1, this number expressing the atomic fraction of the metals nickel and ruthenium; a is the valence of nickel; b is the valence of ruthenium; n is a number equal in value to that defined by the ratio6/[a(1-x) + bx]and w is a number ranging from 0 to 4. A rare earth promoted nickel chrysotile is the preferred catalyst.

Abstract: A system is proposed for the purification of exhaust gases from internal combustion engines, preferably the reduction of nitrogen oxides in exhaust gases from internal combustion engines in which nitrogen is selectively formed as substantially the only nitrogen-containing product. The exhaust gas is contacted at an elevated temperature with a noble metal in a reducing atmosphere, wherein nitrogen oxides are selectively converted to nitrogen as substantially the only nitrogen containing product, and/or is contacted with a noble metal in an oxidizing atmosphere, wherein carbon monoxide and unburned hydrocarbons are converted to carbon dioxide and water, said noble metal being distended on a microporous glass body. In a preferred embodiment the exhaust gas is contacted at an elevated temperature in a reducing atmosphere with ruthenium supported on a microporous glass body comprising a leached, phase-separated alkali borosilicate.
