  • Patent number: 9776937
    Abstract: In a feed clean-up process at least two adsorbents (2, 4) are installed in front of an oligomerization reactor (3). Olefin feed is sent over one adsorbent (2) and the nitrile poisons are adsorbed so that clean feed will enter the reactor (3). Before the adsorbent (2) will be saturated, the feed (1) is sent to the other, fresh adsorbent (4). At the same time oligomerization product from the reactor (3) is used to desorb nitriles from the spent adsorbent (2).

  • Patent number: 9771521
    Abstract: A method of reforming a heavy hydrocarbon distillate, which includes treating a heavy hydrocarbon distillate and a lignocellulosic biomass with a solvent, is provided. The method can be useful in maximizing conversion of the heavy hydrocarbon distillate into higher value-added distillate, for example, naphtha and a middle distillate, and allowing a sulfur compound produced by the decomposition of a heavy hydrocarbon distillate to catalyze pretreatment of the lignocellulosic biomass. Also, oxygen, hydroxymethylfurfural (HMF), levulinic acid, formic acid, and sulfuric acid produced by decomposition of the lignocellulosic biomass can catalyze decomposition of a heavy hydrocarbon distillate and lignocellulosic biomass, thereby activating decomposition of a heavy hydrocarbon distillate.
