Liquid mixture suitable as gasoline

Integrated process for the production of butene-1 which comprises feeding a C.sub.4 hydrocarbon stream to a separation unit of butene-1 and recycling the remaining stream to the same unit after treatment in a bond isomerization section to convert the remaining butenes-2 into butene-1, a molecular sieve separation unit is inserted in the cycle operating with the hydrocarbons in a vapour phase, for the purge of the paraffins.

Integrated process for the production of butene-1

Integrated process for the production of ter-amyl alkyl ethers which comprises the feeding of a C.sub.5 hydrocarbon stream to an etherification reactor and the recycling of the remaining stream to the same reactor, after treatment in an isomerization section to convert linear pentenes into reactive isoamylenes. An absorption section on molecular sieves is inserted between the etherification reactor and the isomerization section to eliminate inert hydrocarbons, basically i-pentane and n-pentane.

Integrated process for the production of ter-amyl alkyl ethers

An integrated process for the simultaneous production of alkyl tert-butyl ethers and 1-butene, comprising feeding a C.sub.4 hydrocarbon stream to an etherification unit and recycling the remaining stream to the same unit after possible separation of the 1-butene and treatment in an isomerization section to convert the remaining butenes into isobutene, a molecular sieve separation unit operating with the hydrocarbons in the vapour phase being incorporated into the cycle.
