Embodiment 1

[0116] Production of α-Olefins from Fatty Acids

[0117] Production of alpha-olefins from distilled C16 fatty acid feedstock. Wax esters were formed via esterification by feeding 200 g of fatty acid into a stirred reactor along with 1.5 molar excess of C16 fatty alcohol. Esterification was carried out at atmospheric pressure at 250°C. The reaction time was 3 hours. No catalyst is used. The water liberated in the reaction was purged with a nitrogen flow of 6 1 / h.

[0118] Thereafter the obtained wax esters and hydrogen are fed into a fixed bed hydrogenation reactor where they are contacted with a copper chromite catalyst at 230° C. and a pressure of 30 MPa to form C16 fatty alcohols. The product is cooled and the liquid crude fatty alcohol is separated. A portion of the fatty alcohol produced is used for esterification.

[0119] The fatty alcohols obtained above were dehydrated in a continuous reactor with a zirconia / γ-alumina catalyst prepared from zirconium tetrachlorid...

[0122] Oligomerization of α-Olefins in a Batch Reactor

[0123] 50 g of 1-hexadecene and 2 g of catalyst were mixed in a kettle reactor. The catalysts used are shown in Table 3 below. The mixture was heated to 200° C. for 24 hours under nitrogen atmosphere. The pressure is 2.0MPa. The conversion of the reaction was calculated as all products except C16.

[0129] Oligomerization in Fixed Bed Reactors

[0130] 1-Hexadecene was fed into a fixed bed tube reactor with 5 g of catalyst diluted with silicon carbide at a ratio of 1:3. The catalyst used was the mesoporous material MCM-41 described in Example 2, with an aluminum content of 2.5 wt%, an amount of acid sites of 150 μmol / g, and a surface area of ​​mesopores >800 m 2 . The reactor temperature is 200° C., the pressure is 2.0 MPa, and the feed rate is 10 g / h. GC analysis was performed after the reaction. In Table 4, the conversion and composition of the oligomerization products at different times in the process are given.

Abstract

A feedstock originating from renewable sources is converted to branched and saturated hydrocarbons without heteroatoms in the base oils distillation range by converting the fatty acids to olefins, which are subsequently oligomerised.

Description

technical field [0001] The present invention relates to a process for the production of hydrocarbons, in particular branched saturated hydrocarbons from renewable sources, and to a process for the production of hydrocarbons and especially polyalphaolefins suitable for use in base oils. The process comprises an olefin preparation step followed by an olefin oligomerization step and a hydrogenation step. Background of the invention [0002] Base oils are used in the manufacture of automotive lubricants, such as engine and transmission oils, and lubricants for industrial applications, such as greases, process oils, white oils and metalworking oils. Lubricants are base oil formulations that often contain additives to enhance their performance for specific applications. Additives more commonly used in lubricant formulations are oxidation inhibitors, rust inhibitors, metal deactivators, anti-wear agents, extreme pressure additives, pour point depressants, detergent-dispersants, vi...
