Embodiment 1

[0025] Mixed hydrochloric acid and zinc chloride (ZnCl 2 ) and stirred at room temperature and normal pressure to form a mixed solution (hydrochloric acid 2wt%, zinc chloride 257 grams). Add bagasse to 100 g of the mixture (14.21 g of bagasse) to carry out a dissolution reaction (temperature 98° C., time 10 minutes). After the bagasse dissolves, a reddish-brown homogeneous liquid is obtained. Afterwards, 100 g of hydrochloric acid (2 wt %) aqueous solution was added into the reddish-brown homogeneous liquid (temperature 100° C., time 10 minutes). The pH of the mixed solution is measured to be 1-2, and a concentrated solution (containing biomass hydrolyzate) and a filtrate (containing divalent metal salts) are obtained through solid-liquid separation. Next, measure the total weight of reducing sugars with high performance liquid chromatography (HPLC method), and calculate the yield of reducing sugars. Reducing sugars may include glucose, xylose, mannose, arabinose and oligosa...

Embodiment 2

[0027] Mixed hydrochloric acid and zinc chloride (ZnCl 2 ) and stirred at room temperature and normal pressure to form a mixed solution (hydrochloric acid 2wt%, zinc chloride 257 grams). Add bagasse to 100 g of the mixed solution (40 g of bagasse) to carry out a dissolution reaction (temperature 98° C., time 10 minutes). After the bagasse dissolves, a reddish-brown homogeneous liquid is obtained. Afterwards, 100 g of hydrochloric acid (2 wt %) aqueous solution was added into the reddish-brown homogeneous liquid (temperature 100° C., time 10 minutes). The pH of the mixed solution is measured to be 1-2, and a concentrated solution (containing biomass hydrolyzate) and a filtrate (containing divalent metal salts) are obtained through solid-liquid separation.

Embodiment 3

[0029] Mixed hydrochloric acid and zinc chloride (ZnCl 2 ) and stirred at room temperature and normal pressure to form a mixed solution (hydrochloric acid 2wt%, zinc chloride 257 grams). Add bagasse to 100 g of the mixture (50 g of bagasse) to carry out a dissolution reaction (temperature 98° C., time 10 minutes). After the bagasse dissolves, a reddish-brown homogeneous liquid is obtained. Afterwards, 100 g of hydrochloric acid (2 wt %) aqueous solution was added into the reddish-brown homogeneous liquid (temperature 100° C., time 10 minutes). The pH of the mixed solution is measured to be 1-2, and a concentrated solution (containing biomass hydrolyzate) and a filtrate (containing divalent metal salts) are obtained through solid-liquid separation. Next, measure the total weight of reducing sugars with high performance liquid chromatography (HPLC method), and calculate the yield of reducing sugars.

Abstract

A method for separating hydrolysis product of biomass is provided. The method includes providing a mixture solution containing a hydrolysis product of biomass and a divalent metal salt, adjusting the pH value of the mixture solution to between 1-4.6, and performing a filtering procedure on the mixture solution using a nanofiltration membrane to obtain a concentrated solution and a filtrate, wherein the concentrated solution mainly includes the hydrolysis product of biomass and the filtrate mainly includes the divalent metal salt.

Description

technical field [0001] The present invention relates to a separation method, more particularly to a separation method of biomass hydrolyzate using a nano-membrane filtration procedure. Background technique [0002] The world is facing the problem that oil reserves are gradually being exploited and the greenhouse effect of the earth's atmosphere continues to expand. In order to ensure the sustainable survival of human beings, it is a world trend to gradually reduce the use of fossil energy and petroleum raw materials, and to develop new renewable forms of energy and raw materials. . [0003] Lignocellulose is the main component of biomass and is the most abundant organic substance on earth. The composition of lignocellulose is mainly composed of cellulose, hemicellulose and lignin, the proportions of which are about 38-50%, 23-32% and 15-25%. Glucose can be produced after hydrolysis of cellulose, and glucose can be converted into alcohols (ethanol or butanol, etc.), organic...
