Ethylene plants produce a C4 butadiene-rich cut as a by-product. Although it has been a highly valued chemical intermediate for a long time, butadiene is now in over supply due to the installation of new steam cracking plants and the growing use of naphtha, the main butadiene generator, as feedstock. In the meantime, the demand for alkylate and ethers has increased steadily to produce environmentally friendly gasoline. This paper presents processes developed by IFP to convert surplus butadiene into ethers or alkylate for gasoline production. The first process transforms the butadiene-rich stream into a butenes-rich stream, an ideal alkylation feedstock. The second process generates isobutene from the butenes stream by skeletal isomerization for MTBE production.
