Embodiment 1

[0065] Embodiment 1 Sodium sulfite direct cooking prepares ethanol

[0066] (1) Cooking corn stalks with sodium sulfite

[0067] Sodium sulfite was added to the corn stover for cooking with a substrate concentration of 20% and a sodium sulfite concentration of 2% (w / w). Mix well, heat and boil after sealing, the temperature is 165°C, and the time is 90 minutes. After cooking, the material is extruded to separate solid and liquid. Add hot water at 80°C to the solid, stir and mix thoroughly, and then carry out the second solid-liquid separation.

[0068] (2) Preparation of organic fertilizer by separating liquid phase

[0069] Combine the liquids obtained by the two separations, add the fermentation residue, mix well, evaporate and concentrate to obtain solid fulvic acid fertilizer. The ratio of the mixed liquor to the added fermentation residue is 1:1. The w / w content of fulvic acid in the obtained fertilizer was 21.6%.

Embodiment 2

[0073] Embodiment 2 Ammonium sulfite direct cooking prepares ethanol

[0074] (1) Cooking corn stalks with ammonium sulfite

[0075] Ammonium sulfite was added to corn stover for cooking with a substrate concentration of 20% and ammonium sulfite concentration of 2% (w / w). Mix well, heat and cook after sealing, the temperature is 185°C, and the time is 90 minutes. After cooking, the material is extruded to separate solid and liquid. Add hot water at 80°C to the solid, stir and mix, and then carry out the second solid-liquid separation.

[0076] (2) Preparation of organic fertilizer by separating liquid phase

[0077] Combine the liquids obtained by the two separations, add the fermentation residue, evaporate and concentrate to obtain solid fulvic acid fertilizer. The ratio of the mixed liquor to the added fermentation residue is 1:1. The content of fulvic acid in the obtained fertilizer is 19.7%.

Embodiment 3

[0081] Embodiment 3 alkali treatment prepares ethanol

[0082] (1) adding sodium hydroxide and ammonium sulfite for cooking

[0083] Sodium hydroxide and ammonium sulfite were added simultaneously to the corn stover for cooking, the substrate concentration was 20%, the sodium hydroxide concentration was 3% (w / w), and the ammonium sulfite concentration was 2% (w / w). Heat and cook after sealing, the temperature is 185°C, and the time is 90 minutes. After cooking, the material is extruded to separate solid and liquid. Add hot water at 80°C to the solid, stir and mix, and then carry out the second solid-liquid separation.

[0084] (2) Preparation of organic fertilizer by separating liquid phase

[0085] Combine the liquids obtained by the two separations, add the fermentation residue, evaporate and concentrate to obtain solid fulvic acid fertilizer. The ratio of the mixed liquor to the added fermentation residue is 1:1. The content of fulvic acid in the obtained fertilizer is...

Abstract

The invention provides a method for producing biology liquid fuel through biomasses. A high value-added solid fertilizer or a liquid fertilizer can be obtained while the biology liquid fuel with the high concentration is prepared. The method at least includes the steps that sulfite or hydrosulphite are added into biomass raw materials, the mixture is heated for cooking, the cooked materials are subjected to solid-liquid separation to obtain a liquid phase and a solid phase containing cellulose, an auxiliary material is added into the liquid phase to form the solid fertilizer or the liquid fertilizer, an enzyme preparation is added into the solid phase containing the cellulose for hydrolysis and sugar production, and the biology liquid fuel is obtained through fermentation of strains into asugar solution. The method for producing the biology liquid fuel through the biomasses can be used in joint production of the biology liquid fuel and organic fertilizers, and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of biology, and in particular relates to a method for producing biological liquid fuel by using biomass. Background technique [0002] Since the 20th century, human society has entered the era of petroleum as the main energy source and chemical raw material. With the development of industrial technology and the improvement of people's living standards, the demand for automobiles has also increased. This has brought about two serious problems: 1. Petroleum is a non-renewable energy source with limited reserves. Due to a large amount of exploitation, it is consumed too quickly and has faced an imbalance between supply and demand; 2. The use of petroleum as fuel and chemical raw materials has caused The severe damage to the environment, especially the carbon dioxide and particulate matter emitted by oil burning has caused serious greenhouse effect and air pollution, which has caused serious environmental and social probl...
