摘要：The prepn. of a catalyst for structural isomerisation of a linear 4+c olefin to its corresp. methyl branched isoolefin involves: (a) mixing (i) zeolite powder comprising at least one zeolite with >= one-dimensional pore structure having a pore size sufficiently small to retard by-prod. dimerisation and coke formation and sufficiently large to allow entry of the linear olefin and formation of the isoolefin, (ii) a binder, (iii) water, (iv) 0.1-6 wt.% w.r.t. (i) and (ii) of >= one monocarboxylic or inorganic acid and (v) 0.1-6 wt.% w.r.t. (i) and (ii) of >= one polycarboxylic acid, (b) forming one or more consolidated particles from the obtd. mixt. and (c) calcinating the particles at 200-700[deg]C.. The structural isomerisation of a linear 4+C olefin to its methyl branched isoolefin involves contacting with the above catalyst at 200-650[deg]C.
