Problems solved by technology

[0006] However, the standard of chemical properties and physical characteristics of wood tar is relatively wide, and the fluctuation is large, which brings great difficulties to the utilization of bio-oil. Caused very large damage, such as corrosion and cracking of pipelines, which seriously reduced the utilization efficiency of biomass resources

Abstract

The invention discloses a lignin hydrodeoxygenation oil dechlorinating process in the field of biomass oil. The lignin hydrodeoxygenation oil dechlorinating process is characterized by including the following steps that 1, hydrodeoxygenation oil, water and an additive are transported to a mixed for full mixing through a pump according to a certain flow; 2, the fully mixed mixture in the step 1 is fed into a vertical oil-water separator; 3, oil is discharged from the upper portion of the separator, and water is discharged from the lower portion to achieve oil-water separation. The lignin hydrodeoxygenation oil dechlorinating process is simple in process, industrialization is easily achieved, the inorganic chlorine and organic chlorine content in an oil phase can be remarkably reduced, the damage to equipment, a catalyst and the like is reduced, and the utilization efficiency of biomass resources is improved.

Description

technical field [0001] The invention belongs to the field of biomass oil production and processing, and in particular relates to a dechlorination process of wood hydrodeoxygenated oil. Background technique [0002] Organic matter of plant and animal origin is defined by the U.S. Department of Energy (DOE) as biomass. Biomass is composed of five basic elements, C, H, O, N, and S, all of which are composed of CO in the air 2 And water is produced through photosynthesis, so it is also known as green coal for instant use. Generally speaking, biomass mainly comes from woody, non-woody, and animal manure. With the increasing depletion of traditional fossil fuels and people's concern for the environment, tar, a by-product of biomass pyrolysis, is a green and environmentally friendly renewable resource. will become even more important in the future. [0003] As a kind of biomass fuel, wood tar mainly comes from the production of mechanism charcoal. It uses sawdust and waste plant...
