Molded bodies in the form of packing bodies comprising a macroporous strongly acid or basic ion exchange resin having a voids fraction of 5-95 vol % of the macro shape without pores, a BET surface area of 0.1-1,000 sq m/g, and an ion exchange capacity of 0.05-10 meq/g.

Molded bodies comprised of macroporous ion exchange resins, and use of

A process for dehydrogenating saturated or unsaturated hydrocarbons wherein the flow direction of the oxygen-containing gas, employed for removing coke deposits on the catalyst surface, is opposite to that for the hydrocarbon feed undergoing dehydrogenation.

Method for dehydrogenating hydrocarbons

A process for producing sec-butanol and sec-butyl tert-butyl ether from butane comprises: (a) partially isomerizing n-butane to produce a mixture of n-butane and isobutane; (b) catalytically dehydrogenating said butanes to produce a mixture containing at least butene-1, isobutene and butadiene; (c) selectively hydrogenating butadiene and converting butene-1 to butene-2; (d) etherifying isobutene contained in the dehydrogenation reaction mixture with sec-butanol to form a mixture of sec-butyl tert-butyl ether and unreacted hydrocarbons; (e) converting butene-2 from the unreacted hydrocarbon mixture by hydration to produce sec-butanol; (f) recycling said sec-butanol to the etherification step; recovering said sec-butyl tert-butyl ether.
