Abstract

The invention discloses emulsified biomass fuel oil, which comprises the following components in percentage by weight: 1 to 15 percent of biomass crude oil, 75 to 95 percent of diesel oil, 0.45 to 9 percent of emulsifying agent, 0.05 to 0.2 percent of co-surfactant, 0.01 to 0.06 percent of oxidation and corrosion inhibitor and 0.01 to 1 percent of isooctyl nitrate. A preparation method for the emulsified oil comprises the following steps of: filtering the biomass crude oil to remove coarse impurities, and removing heavy components from the biomass crude oil by using a centrifugal machine; and then, adding ester emulsifying agent and ether emulsifying agent into the diesel oil and the biomass crude oil respectively, adding the two kinds of mixed solution into a high-shear homogenizing emulsifier, stirring the mixed solution for 20 to 60 minutes with shearing at the temperature of between 30 and 50 DEG C under 1,500 and 3,000rpm, finally adding the co-surfactant, the oxidation and corrosion inhibitor and an inflame improver into the mixed solution, and uniformly emulsifying the mixed solution to obtain the emulsified biomass crude oil. The emulsified biomass crude oil has long stabilization time which can reach over 6 months; the emulsified biomass crude oil has the advantages of high utilization rate of biomass oil, good anti-oxidation stability, low corrosion, low ash content and high combustion heat value; and the preparation method is simple and feasible, and has low environmental pollution.

Description

1. Technical field [0001] The invention relates to a quality-improved and modified biomass crude oil and a modification method thereof, in particular to an emulsified biomass crude oil obtained by direct emulsification and an emulsification method thereof. 2. Background technology [0002] Biomass is the most common renewable clean energy on earth, with the advantages of high volatile components, high carbon activity, low sulfur content, and low ash content. Among the utilization technologies of biomass energy, flash pyrolysis liquefaction to produce bio-oil is a cutting-edge technology. Scholars at home and abroad have conducted a lot of research on this technology, expecting to convert biomass into convenient storage and transportation and high energy density. Bio-oil. The pyrolysis preparation of biomass oil is relatively mature (Bai Xueyuan, Yi Weiming, Wang Lihong Research on rapid pyrolysis and liquefaction of corn stalks in a fluidized bed heated by plasma[J].
