Abstract:
1. An improved OXO process with converted waste oil recycle comprising: a. hydroformylating an olefin with synthesis gas in a reactor to produce an OXO product as well as by-product waste oil, the by-product waste oil having a lower or higher boiling temperature than said OXO product; b. separating OXO product from the by-product waste oil; c. converting separated waste oil to synthesis gas comprising evaporating the waste oil with hydrocarbon gas in an evaporator vessel to provide a mixed vapor stream of hydrocarbon gas and evaporated waste oil and directly oxidizing the mixed vapor stream to provide synthesis gas; and d. recycling the synthesis gas produced in step (c) to the reactor of step (a).
