Problems solved by technology

However, the production of biofuels from grains not only cannot meet social needs, but also endangers food security
Some researchers pointed out that even if all the corn and soybeans grown in the United States were used to produce bioenergy, they could only meet 12% of the gasoline demand and 6% of the diesel demand of the American society respectively.

Embodiment 1

[0041] 1. Preparation of cassava flour

[0042] The raw material cassava is dedusted, impurity removed and purified, and then enters the pulverizer to form dry cassava flour.

[0043] 2. Gelatinization

[0044] (1) Weigh 960 grams, 1200 grams, 1440 grams, 1680 grams of cassava flour and auxiliary material medium respectively, wherein the auxiliary material medium is 9.6 grams, 12 grams, 14.4 grams, and 16.8 grams respectively. In this step, the supplementary culture medium accounts for 1% of the total amount.

[0045] The auxiliary medium has the following components: 50 grams of corn starch, 40 grams of protein, 9.7 grams of fat, 0.1 grams of lysine, vitamin B 1 0.05 g, B 2 0.05 grams;

[0046] (2) Add a certain amount of water and waste mash into the four gelatinization tanks, and heat.

[0047] (3) Take the slightly hot water in the gelatinization tank, and adjust the mixture into a lump-free paste. After the water in the tank boils, add it to the four tanks separate...

Embodiment 2

[0067] a, take by weighing 1680 grams of cassava flour and adjuvant culture medium, wherein 504 grams of adjuvant culture medium, add water and processed waste mash deployment and heat gelatinization, the concentration of gelatinization liquid is controlled at 10%;

[0068] In this step, the supplementary culture medium accounts for 30% of the total amount. The auxiliary medium has the following components: 60 grams of corn starch, 33.7 grams of protein, 5.7 grams of fat, 0.2 grams of lysine, vitamin B 1 0.001 g, B 2 0.001 g;

[0069] b. After the gelatinized liquid is sterilized and cooled, it is used as a culture medium and added to the seed tank;

[0070] c. After adding Clostridium acetobutylicum into the mother tank, inoculation, breeding and continuous fermentation are carried out; the fermentation temperature is 41°C. The fermentation period is controlled at 120h.

[0071] The products made in this embodiment are shown in Table 3 for details.

Abstract

The invention discloses a new method for producing biofuel butanol, comprising the following steps: a. tapioca flour and accessory medium are added with water and blended with processed waste mash, and then gelatinized by increasing the temperature, with the concentration of gelatinization solution controlled between 2 percent and 15 percent; b. after being sterilized and cooled, the gelatinization solution is added into a breeding pot as medium; c. after protane-butane fusiform bacteria is added into the breeding pot, inoculation, breeding, even the fermentation are carried out; and d. when the fermentation broth is separated by a mash tower and then distillated by a distillation tower, biofuel butanol is obtained. The invention uses plants which have high yield and are also not used as human food as raw materials to produce the biofuel butanol, thus providing a clean and efficient biofuel.

Description

technical field [0001] The invention relates to a method for preparing biofuel, in particular to a method for preparing biofuel butanol. Background technique [0002] With the depletion of petroleum resources, the whole world is turning the focus of energy research to biofuels. At present, biofuels such as biodiesel, ethanol fuel, butanol fuel have been applied. In practical applications, biofuel butanol can effectively improve the fuel efficiency and mileage of vehicles because it can be mixed with gasoline in any ratio without modification of vehicles, and its economy is high. Therefore, biofuel butanol has superior quality and higher calorific value conversion rate than bioethanol. Therefore, the biofuel butanol will win people's favor even more. The traditional preparation method of bio-butanol is prepared by fermenting corn, wheat, soybean and other grains as raw materials. However, the production of biofuels from grains not only cannot meet social needs, but also e...
