Abstract: This invention relates to a process for restructuring an olefinic feedstock rich in linear olefins into a product olefin of narrower composition which is richer in branched olefins than the starting feedstock. Such restructuring is achieved by contacting the feedstock with an unmodified or partially modified tectometallosilicate of the Theta-1 type at relatively low temperatures. The product olefins are valuable as petrochemical feedstock for producing polyolefins, alcohols, ethers and other oxygenates, surfactants, alkyl aromatics and oligomers useful as gasoline blending components.

Abstract: A catalyst precursor for use after reductive activation in the conversion of synthesis gas to methanol having the formula:

wherein

A is an alkali metal,
a is from 0.1 to 4,
b is from 0 to 0.5, and
x is a number such that the valence requirements of the other elements for oxygen is satisfied,

is prepared by the steps of (I) precipitating at a temperature below 50°C the metals copper and thorium in the form of insoluble thermally decomposable compounds thereof using a precipitant comprising a carbonate and/nr bicarbonate of an alkali metal and/or ammonium, the pH being adjusted to a final value in the range from 5 0 to 7 0 (II) recovering the precipitate obtained in step (I), and (III) thermally decomposing thermally decomposable compounds comprised in the precipitate recovered in step (II), the maximum temperature utilised in the thermal decomposition being in the range from 300 to 600°C. Also a catalyst composition of formula Cu a .Th0 2 wherein a is from 0.1 to 4 and wherein at least 30% of the elemental copper particles are of a size less than or equal to 20 Angstroms.
