Embodiment 1

[0069]Example 1: Taking the 5L scale-up test as an example, the raw material of starch and / or cellulose is catering waste. First, solid-liquid separation is carried out on the catering waste, and the food part is left after the solid matter is removed from metal, glass, bamboo, wood, earth and stone, and plastic debris. The food part is crushed and mixed with water at a ratio of 1:3. Put about 2700ml slurry of the crushed and slurried organic waste food into the microwave hydrolysis and saccharification reactor of the process shown in Figure 1 for hydrolysis. Its hydrolyzed slurry composition is as follows: food starch 180g (pure starch), add catalyst dilute hydrochloric acid 900mL and cocatalyst metal halide (such as FeCl 3 ) solution 450mL, add 1500ml pure water to dilute, shake well, the total liquid is about 3000ml. The reactant was hydrolyzed for 6 minutes in the microwave tank reactor shown in Figure 1, and then sent to the second microwave reactor (two microwave tube ...

Embodiment 2

[0072] Example 2: 4M 3 Stainless steel tank reactor scale-up test. at 4M 3 For the stainless steel tank reactor (not connected to the microwave tube reactor in the loop), refer to the catering waste treatment method and the chemical batching method of the above-mentioned embodiment 1, and pre-hydrolyze for 8 minutes. Then it is sent to two secondary microwave reactors connected in series for further hydrolysis reaction for 120 seconds. The yield of glucose was determined to be 97.60% by enzymatic method in literature.

Embodiment 3

[0073] Embodiment 3: The present invention can provide an industrial technical device for the industrialization of the following microwave hydrolyzed starch laboratory research: the frequency of the experimental microwave oven is 2450MHz, and the power is 800w. Add 0.2000g of starch to the reactor, add 2.00mL of dilute hydrochloric acid, and add 1.00mL of 0.15M[X - ] Metal halide solution, shake well and cover to carry out microwave reaction, take out and adjust pH to 7 with NaOH, pour into 25mL volumetric flask with water to volume, pipette 5.00mL into 50mL volumetric flask with water to volume, measure glucose content. The experiment investigated the factors affecting the hydrolysis of starch to glucose, such as the influence of hydrochloric acid concentration on glucose yield, the influence of NaCl on glucose, the influence of various metal chlorides on yield, the influence of other metal halides on yield, and the influence of sulfate on yield. The effects of metal halides ...

Abstract

The invention discloses a device to hydrolyze amidon and / or cellulose to produce fuel alcohol assisted by industrialized microwave, which is characterized by the following: arranging amidon and / or cellulose microwave hydrolysis saccharifying reaction unit between raw material preprocessing unit and microbe ferment unit; connecting through pipe; setting the amidon and / or cellulose microwave hydrolysis saccharifying reaction unit as microwave autoclave or microwave pipe reactor; cascading first microwave reactor at by-pass of the microwave reactor or pipe reactor to heat reactant and activator. This device adopts special microwave static reactor device, which can reach chemical equilibrium of hydrolytic reaction quickly.

Description

technical field [0001] The invention relates to a device for producing fuel ethanol. The present invention particularly relates to an industrialized microwave-assisted hydrolyzing device for producing fuel ethanol from starch and / or cellulose. The raw material for microwave hydrolysis may be grain starch and plant starch, or may come from catering waste and starch and / or cellulose-containing Organic waste, as well as cellulose-containing agricultural waste and industrial waste such as bagasse, sugar waste honey, and apple pomace. Background technique [0002] The carbohydrates with a large amount in nature are cellulose and starch, which are a kind of huge potential energy and renewable resources. However, many industrial and agricultural wastes mainly composed of cellulose and starch carbohydrates, such as straw, wood waste, sulfite pulp waste, urban waste, and catering waste, have not been well utilized and have become social nuisances. With the increase of the world pop...
