Abstract
Official abstract text for this publication.
Embodiments of the present invention relate to drilling oil, and to a method of preparing the drilling oil, including converting C16 and/or C18 fatty acids derived from fat of biological origin into C15 and/or C17 olefins through decarbonylation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A drilling oil, comprising mixed C15 and C17 linear alpha and internal olefins, wherein a weight ratio of C15 linear olefin to C17 linear olefin is 99:1˜1:99, a weight ratio of internal olefin (LIO) relative to a sum of C15 and C17 α-olefin (LAO) and internal olefin (LIO) of the mixed C15 and C17 linear olefins is at least 0.1, the mixed C15 and C17 linear olefins contain at least 10 wt % of a polyolefin having two or more double bonds, and the drilling oil has (i) a flash point of 85° C., or more, (ii) a pour point of less than −5° C., (iii) a density of 0.77˜0.81 g/cm 3 , and (iv) a kinematic viscosity of 1.9˜3.5 cSt (40° C.). 2. The drilling oil of claim 1 , wherein an amount of the mixed C15 and C17 linear olefins in the drilling oil is at least 80 wt %. 3. The drilling oil of claim 1 , wherein the drilling oil contains 5 wt % or less of an aromatic compound. 4. The drilling oil of claim 1 , wherein the drilling oil has a boiling point of 250˜330° C. 5. The drilling oil of claim 1 , wherein the drilling oil has (i) the flash point of 110˜113° C., (ii) the pour point of less than −15° C., (iii) the density of 0.775˜0.808 g/cm 3 , and (iv) the kinematic viscosity of 1.9˜3.5 cSt (40° C.).
