Biodiesel prepared by non-edible vegetable oil and method thereof

Abstract

The invention relates to biodiesel prepared by non-edible vegetable oil and a method thereof, which belong to the biodiesel field. By-product milk thistle oil produced during the production process of Silibinin serves as a raw material for preparing the biodiesel. The biodiesel is obtained by transesterification of the milk thistle oil and methyl alcohol under the condition of a catalyst. Gas chromatography-mass spectrometry analysis results show that main components of the biodiesel prepared by the milk thistle oil serving as the raw material are methyl oleate and methyl linoleate. The biodiesel is high in cetane number, excellent in performance and capable of meeting China current biodiesel standard. In addition, the biodiesel is simple in process, mild in reaction condition, low in cost and capable of achieving large-scale production.

Description

technical field

[0001] The invention relates to a biodiesel prepared from a novel non-edible vegetable oil and a method thereof, in particular to a biodiesel prepared from non-edible milk thistle oil and a method thereof, belonging to the field of biodiesel. Background technique

[0002] As an important resource in today's world, oil has greatly promoted modern civilization and made great contributions to human life. However, with the sharp increase in demand for petrochemical products, the reserves of oil, a non-renewable resource, are decreasing day by day. Some experts predict that oil will be exhausted in the next few decades. Biodiesel has attracted widespread attention due to its rich source of raw materials, outstanding environmental protection and good renewability. It is a clean and safe new fuel produced by using animal and vegetable oils and high acid value oils. It is mainly produced by catalytic transesterification of these oils with some short-chain alcohols (...
