Embodiment 1

[0072] Select domestic waste from the waste compression and transfer station in Haidian District, Beijing, and carry out high-temperature distillation carbonization on the above-mentioned waste through the following steps: (1) put the waste into the waste transport device; (2) pass the waste transport device through the high-temperature distillation carbonization (3) take out the gas stream of crude biomass oil and steam from the upper part of the high-temperature distillation carbonization device; (4) make the gas stream pass through the catalyst bed in gaseous form; (5) condense the effluent from the catalyst bed, A mixture of upgraded biomass oil and water is obtained. The high-temperature distillation carbonization device is heated by high-temperature oxygen-free steam, the temperature of the high-temperature oxygen-free steam is 400°C, the nitrogen content in the high-temperature oxygen-free steam is 15v.%, the average treatment time is 8.0 hours, and the pressure is 0.5MP...

Embodiment 2

[0074] Using the mixture of upgraded biomass oil and water obtained in Example 1 for CO 2 Supercritical fractionation treatment. Mix 1.5L of the mixture of biomass oil and water prepared in Example 1 with clean porous glass balls (diameter 2mm, macroscopic volume is 200mL), then place in a fractionator (capacity is 3L), at 45 ℃ with 50g / min of CO 2 The flow rate is fractionated, the fractionation pressure is 25MPa, and the fractionation time is 2h, and the first fraction and the second fraction are fractionated; then the pressure is increased to 30MPa, and the remaining biomass oil fraction (the third fraction) is collected. The water content in the three fractions was tested by Karl Fischer titration, the water content of the first fraction was 0.11%, the water content of the second fraction was 0.07wt.%, and the water content of the third fraction was 1.1%. In addition, it has been tested that the calorific value of the first fraction is 47MJ / kg, the calorific value of th...

Abstract

The invention provides biomass oil with low oxygen content and low water content and a preparation method thereof, and the biomass oil has various good properties, such as high calorific value, so that the biomass oil can be applied to various fields.

Description

technical field [0001] The invention belongs to the field of fuel technology, and in particular relates to biomass oil with low oxygen content and low water content and a preparation method thereof. Background technique [0002] Fossil fuel alternative energy has attracted much attention, and biomass oil is considered to be a promising alternative energy. However, the complex composition of bio-oil results in significantly lower oil products, such as low calorific value, poor chemical stability, and severe corrosion to equipment. The poor crude oil quality of biomass oil usually requires subsequent modification and upgrading to meet the requirements of fuel oil. Require. The upgrading of biomass oil mainly includes hydrodeoxygenation, catalytic cracking, catalytic reforming and catalytic esterification. Catalytic upgrading can change the composition of biomass oil and fundamentally change the quality of biomass oil. Key technologies such as yield and efficiency in producti...
