Abstract
A method includes brominating a butanes feed stream including i-butane in a bromination reactor to form a bromination effluent stream including t-butyl bromide. The method includes dehydrobrominating the t-butyl bromide to form isobutylene. Another method includes brominating a mixed pentanes feed stream including i-pentane and n-pentane in a bromination reactor to form a bromination effluent stream including t-pentyl bromide. The method includes dehydrobrominating the t-pentyl bromide to form isoamylene and HBr.
Claims13
A method comprising:
- brominating a butanes feed stream comprising i-butane in a bromination reactor to form a bromination effluent stream comprising t-butyl bromide, polybromides, and unreacted i-butane;
- separating the polybromides from the brominated compound stream;
- hydrogenating the polybromides with hydrogen to form a hydrogenation recycle stream;
- recycling the hydrogenation recycle stream to the bromination effluent stream;
- and
- dehydrobrominating the t-butyl bromide to form isobutylene and HBr.
