Abstract

The invention discloses a production device and a production method for distribution type plant oil transesterification. The production device comprises an equipment frame, a reaction kettle, a washing tank, a catalyst recovering tank, a drier, a warm water storage tank, a heat conducting oil heating tank, a reaction circulating pump, an air pump, a material pump and a heat conducting oil pump. The production method comprises the following steps of: heating and stirring a mixture of plant fat raw material oil, low-carbon alcohol and a pyridyl trifluoromethanesulfonate ion liquid catalyst to react for 3-5 hours; standing so that reaction materials are divided into a light phase and a heavy phase, and separating the light phase from the heavy phase; standing the heavy-phase material and naturally cooling, so that the catalyst is precipitated to the bottom, and the rest is crude glycerol containing alcohol; adding warm water to the light-phase material for washing, and then standing so that the light phase and the heavy phase are formed again; and pumping the light-phase material into the drier for drying, so as to obtain the plant oil. The production method disclosed by the invention can achieve homogeneous catalysis and different-phase separation through process integration, and the yield of the plant oil is improved; and the production device disclosed by the invention is handy and simple, and is convenient for real-time processing of a dispersed raw material.

Description

technical field [0001] The invention relates to a processing technology and a device for producing biodiesel and lubricating oil base oil through transesterification reaction of vegetable fats and oils, in particular to a process integrated distributed transesterification reaction of vegetable fats and oils to produce biodiesel and lubricating oil base oil production Processing technology and its equipment. Background technique [0002] Esterification is a common type of reaction in organic chemistry. A series of ester compounds and environmentally friendly biofuels can be synthesized through this type of reaction, which are widely used in fine chemicals and petrochemical energy. The transesterification reaction of vegetable oils can produce biodiesel and ester synthetic lubricant base oils. Biodiesel is a liquid fuel that is processed from biomass resources and has properties similar to diesel. As an important branch of the biorefinery industry, biodiesel has an important...
