Abstract
A process for selectively producing oligomers may comprise bringing at least one antifouling agent into contact with a first amount of at least one aluminum alkyl compound to form at least one antifouling compound comprising the structure or its dimeric form; and feeding the at least one antifouling compound, an additional amount of the at least one aluminum alkyl compound, at least one titanate compound, and ethylene into a jet loop reactor and oligomerizing ethylene to produce one or more of 1-butene, 1-hexene, or 1-octene. One or more of the chemical groups R1, R2, and R3 may be the antifouling agent comprising the structure —O((CH)O)R4. n may be an integer of from 1 to 20. m may be an integer of from 1 to 100. R4 may be a hydrocarbyl group. In embodiments, the chemical groups R1, R2, or R3 that do not comprise the antifouling agent, if any, may be hydrocarbyl groups. The at least one titanate compound may be fed as a stream separate from the streams of the at least one antifouling compound and the additional amount of the at least one aluminum alkyl compound. The of the sum of the first amount and the additional amount of the at least one aluminum alkyl compound to the at least one titanate compound may be equal to or higher than 1.5 and equal to or lower than 3.0.
