Embodiment 1

[0046]Weigh 1 kg of cassava refined starch, put it into the mixing tank, add 9 kg of clear water and soak it at room temperature, so as to dissolve various impurities in the water, add hydrochloric acid to the soaking solution, adjust the pH value to 4, soak for 5 hours Discard the sundries in the upper layer, and soak for three times to end. Adjust the concentration of the washed cassava flour to 17Be, then add 10 grams of S1010 catalyst, the catalytic temperature is 100°C, stir, and the reaction is completed in 0.5 hours. Cool the liquid to 37°C, add CL·a-b Np-1 strain to ferment, the inoculum size is 150 grams, and after inoculation, keep it at 42°C for 50 hours to ferment to produce a mixture of bio-butanol, acetone and ethanol. First, the mixed solution is distilled to a solvent solution with a concentration of about 30% through a rectification tower, and the temperature is controlled at 90°C, and then the mixed solution is separated at 70°C to separate acetone and ethano...

Embodiment 2

[0048] Weigh 100 kg of cassava chips, crush them, put them into the pulping tank, add 1000 kg of clear water to soak, so that various impurities can be dissolved in water, and add N a OH, adjust the pH value to 9, soak for 10 hours and discard the upper debris, and end the second soak. Adjust the concentration of the cleaned cassava flour to 20Be, then add 1 kg of S1010 catalyst, and stir at a catalytic temperature of 70°C. After 1.5 hours of reaction, heat up to 100°C and keep it for 20 minutes, then cool the liquid to 32°C, add CL·a-b Np -1 strain fermentation, the inoculum amount is 10 kg, and after inoculation, it is incubated and fermented at 40°C for 70 hours to generate a mixture of bio-butanol, acetone and ethanol. First, the mixed solution is distilled to a solvent solution with a concentration of about 25% through a rectification tower, and the temperature is controlled at 90°C, and then the mixed solution is separated at 78°C to separate acetone and ethanol, and the...

Abstract

The process of preparing fuel oil butanol with cassava material includes the steps of mixing slurry with crushed cassava or cassava starch, adding acid or alkali to soak and to eliminate impurity, adding S1010 to catalyze reaction, cooling, inoculating CL.a-b Np-1 spawn to ferment to obtain mixed liquid, fractionating to obtain coarse fuel oil butanol product, and treating with QR-W absorbent to obtain refined fuel oil butanol product. The refined fuel oil butanol product may be added with QR-E modifier to obtain qualified fuel oil butanol. The process is simple and low in cost, and the present invention provides one new way for producing biofuel oil and utilizing cassava resource.

Description

technical field [0001] The invention relates to a method for preparing fuel bio-butanol from cassava. Background technique [0002] Butanol, the molecular formula is CH 3 CH 2 CH 2 CH 2 OH, colorless liquid, specific gravity 0.8098 (20 / 4°). The boiling point is 117.7°; the freezing point is -89.0°. Soluble in water, miscible with ethanol and ether. Vapor and air form explosive mixture, explosion limit 3.7-10.2% (volume). [0003] Butanol is a very important chemical raw material and a solvent in industrial production processes. Over the years, in some major solvent producing countries, butanol has been mainly used as chemical solvents and dehydrating agents, and for the production of butyl acetate and resins. [0004] At present, there are several production processes of butanol: [0005] (1) It is prepared by condensation hydrogenation with acetaldehyde as raw material. [0006] (2) Preparation of propylene by carbonylation and hydrogenation. [0007] (3) Ferment...
