摘要： (57) [Abstract] The present invention, as it is small enough to retard cokeformation and dimerization of (i) by-products, so as to allow the formation of the methylbranched isoolefin and entry of linear olefins and isomers containing; coke oxidation-promoting metal up to about 15 wt% (iii) and up; (ii) alumina binder; at least one zeolitehaving only in one dimension a pore structure with a large pore size sufficiently relates toa process by contacting at a temperature of 200 ℃ ~650 ℃ and linear olefin catalyst, it isconverted to methyl-branched iso-olefins in the corresponding isomerization conditionslinear olefins. When after a certain operating time, coke the amount which reducesdrastically the activity of the catalyst is deposited on the catalyst, the oxygen content atan elevated temperature for time sufficient stripped hydrocarbons from the catalyst, andto burn off coke (ie, to regenerate the catalyst at a temperature of about 565 ℃ below)is contacted with the gas. After playing, I will continue the isomerization process. It isparticularly desirable for use as coke oxidation promoting metal platinum and / orpalladium.
