Manufacture of butadiene from ethylene |
| abstract |
A method of producing butadiene includes: (1) dimerizing ethylene to butene followed by (2) oxidatively dehydrogenating the butene to butadiene and (3) recovering the butadiene by (i) absorbing the product with a hydrocarbon absorber oil and (ii) stripping a crude product stream from the absorber oil. The absorber oil is selected so as to be effective to sequester ethylene dimerization-derived impurities from the system. |
