A method for the production of a fuel additive includes passing a hydrocarbon stream comprising crude mixed C4 hydrocarbons through a first hydrogenation unit to produce a first product stream; passing the first product stream from the first hydrogenation unit to a methyl tert-butyl ether synthesis unit forming methyl tert-butyl ether and a byproduct stream; passing the byproduct stream through a first distillation unit to separate the byproduct stream into a first 1-butene stream, an isobutane stream, and a 2-butene and n-butane stream; forming a second product stream by passing the 2-butene and n-butane stream to a selective conversion unit; passing the second product stream into a second distillation unit to form an n-butane stream and a second 1-butene stream; passing the second 1-butene stream to a fuel additive production unit; and passing the first 1-butene stream to the fuel additive production unit to form the fuel additive.

A method of manufacturing an octane-boosting fuel additive, the method comprises reacting n-butyraldehyde, iso-butyraldehyde, or a combination comprising at least one of the foregoing with glycerol in the presence of an acidic catalyst to obtain an octane-boosting product mixture comprising 2-propyl-5-hydroxy-1,3-dioxane, 2-isopropyl-5-hydroxy-1,3-dioxane, 2-propyl-5-hydroxymethyl-1,3-dioxolane, 2-isopropyl-5-hydroxymethyl-1,3-dioxolane, or a combination comprising at least one of the foregoing.

Octane-boosting fuel additives, method of manufacture, and uses thereof

A method of manufacturing a cetane-boosting fuel additive includes reacting formaldehyde and 2-ethylhexanol at a mole ratio of 10:1 to 1:1, or 5:1 to 1.5:1, or 4:1 to 2:1, or 3.5:1 to 2.5:1 in the presence of a heterogeneous acid catalyst at a temperature of 300 to 375&#xb0; K to obtain a cetane-boosting product mixture comprising HC(CH)CH(CHCH)CH(OCH)OH, HC(CH)CH(CHCH)CH(OCH)OCHCH(CHCH)(CH)CH, or a combination thereof, wherein n has an average value of 2.8 to 3.2, preferably an average value of 3.

Cetane-boosting fuel additives, method of manufacture, and uses thereof

The present invention relates to a method for preparing linear alpha-olefins (LAO) by oligomerization of ethylene in the presence of solvent and homogenous catalyst, comprising the steps of: (i) feeding ethylene, solvent and catalyst into an oligomerization reactor, (ii) oligomerizing the ethylene in the reactor, (iii) removing a reactor outlet stream comprising solvent, linear alpha-olefins, ethylene, and catalyst from the reactor via a reactor outlet piping system, (iv) transferring the reactor outlet stream to a catalyst deactivation and removal step, and (v) deactivating and removing the catalyst from the reactor outlet stream, characterized in that at least one organic amine is added into the oligomerization reactor and/or into the reactor outlet piping system.

Method for preparing linear alpha-olefins

A method for removal and recovery of an organic amine from a hydrocarbon stream containing the amine, including: i) mixing the hydrocarbon stream containing the amine with an aqueous inorganic acid in a volumetric ratio of hydrocarbon stream:aqueous inorganic acid of greater than 1:1-5:1, preferably 1.5:1-4:1, more preferably 3:1, ii) phase separating of hydrocarbon and aqueous phase; iii) removing the hydrocarbon phase and optionally further purifying thereof, iv) optionally recycling at least a part of the hydrocarbon phase obtained in step (iii) into mixing step (i), v) mixing the aqueous phase obtained in step (iii) with an aqueous alkaline solution, vi) phase separating of an aqueous phase and an organic phase formed, vii) removing the organic phase obtained in step (vi) and optionally further purifying thereof.

Method for removal and recovery of organic amines from a hydrocarbon stream

The present invention relates to a method for processing high molecular weight oligomer waste products formed during the production of linear alpha-olefins by oligomerization of ethylene in a reactor in the presence of a solvent and a catalyst, characterized in that the high molecular weight oligomers are separated in a separation unit from a product stream of the reactor comprising the solvent, the catalyst, linear alpha-olefins and high molecular weight oligomers having a solidification temperature in the range of about 60-100&#xb0; C., then diluted with a dilution medium and heated to about 130&#xb0; C. to about 200&#xb0; C., the diluted high molecular weight oligomers are then transferred to a disposal device, wherein at least some of the dilution medium may be recovered and recycled for addition to the dilution medium.

Method for the preparation of linear alpha-olefins and reactor system therefore with improved disposal of high molecular weight oligomers
