Title:
再生可能なベースオイル、ディーゼルおよびナフサを製造するための方法
Document Type and Number:
Japanese Patent JP7266539
Kind Code:
B2
Abstract:
The present invention relates to the field of hydrotreatment of biological oil, in particular to methods for producing renewable base oil and a diesel oil from low-value biological oils. It was found that low-value biological oils containing free fatty acids and fatty acid esters can be processed into a renewable base oil and a renewable diesel oil in an efficient manner by first separating at least part of the saturated free fatty acids from the feedstock and then processing separately this saturated free acid feed in a ketonisation reaction followed by hydrodeoxygenation and hydroisomerisation reactions to yield a renewable base oil stream. The remaining free fatty acid depleted feed may be processed in a separate hydrodeoxygenation and hydroisomerisation step to yield a renewable diesel stream. Splitting the feedstock into two separate streams, where one is a saturated free fatty acid stream provides surprising advantages compared to a combined treatment of the entire feedstock.
