摘要：In the catalytic cracking of methyl-tert. butyl ether (MTBE), the cracked product(II) is distilled to give an isobutene (IB) head stream (III) and a sump stream (IV) ofdiisobutene, MTBE and methanol. (IV) is distilled to give a sump stream (V) of methanol; aside stream (VI) of diisobutene, methanol and MTBE; and a head stream (VII) of MTBE andmethanol, which is recycled to the cracking stage. A method for cracking methyl-tert.butyl ether (MTBE) involves: (a) cracking MTBE, contained in two streams (I) and (II), over acatalyst; (b) distilling the product (II) to give a head stream (III) containing more than 90wt. % isobutene (IB) and a sump stream (IV) containing diisobutene, MTBE and more than80% of the methanol contained in (II); (c) distilling (IV) to give a sump stream (V)
containing methanol, a side stream (VI) containing diisobutene, methanol and MTBE and ahead stream (VII) containing MTBE and methanol; and (d) recycling (VII) to stage (a).
