Embodiment 1

[0023] The invention is adopted to construct a synthetic gasoline enterprise. First of all, the site of the factory should be selected on the river beach sandy land far away from the residential area, or in the saline-alkaline area; in order to ensure safety, the building must be 500m away from the factory; in order to ensure the freshness of the Chinese herbal medicine, the factory site for the preparation of fermented enzymes should be selected at a distance from the raw materials. The location that the production center is near.

[0024] Process method of the present invention is specifically described as follows in conjunction with accompanying drawing:

[0025] The process for preparing ethanol in the present invention is made of plant stalks as raw materials, which are composed of crushing, soaking, hydrolysis, fermentation, filtration, rough distillation, and rectification. After the raw materials of corn stalks or straws are cleaned, they enter the crushing process , ...

Embodiment 2

[0029] Using the present invention to prepare ethanol and synthesize gasoline, sweet sorghum stalks or rice straw are selected as raw materials; after soaking the materials to remove 20% of water, they are put into a boiling tank for heating and boiling, and the temperature is controlled at 130°C for hydrolysis. 8 hours, heat preservation for 4 hours; the temperature in the tank of the fermentation process is 28°C; the crude distillation temperature is 90°C, and the ethanol concentration of the distillate is 78%; enter the rectification process, the temperature is controlled at 100°C, and the ethanol concentration of the distillate reaches 99%.

[0030] The ingredients for the preparation of fermented enzymes are 80kg of wolf’s tail grass, 10kg of dried yam, 5kg of wheat germ, and 5kg of barley malt; the preparation process is to first cut the wolf’s tail grass into powder, boil it in water, and cool it for later use; then grind the dried yam and malt Put it into fine powder an...

Embodiment 3

[0034] Use tree branches, or bark, or sawdust as raw materials to prepare synthetic gasoline. After the material is soaked, 25% of the water is removed, and then transferred to the boiling tank, the temperature is controlled at 110°C; the crude distillation temperature is 88°C, and the output ethanol concentration is 75%; the rectification temperature is 98°C, and the output ethanol concentration is 97%; the raw materials for fermentation enzyme preparation are 60kg of wolftail grass, 10kg of dry yam, 15kg of wheat malt and barley malt respectively; transfer to the fermentation room, keep a constant temperature of 45°C for 15 days; the raw materials of the synthesis process are 250kg of ethanol and 250kg of methanol , 200kg of intermediate, 250kg of No. 120 solvent oil, 50kg of 5% hydrogen peroxide, fully stirred evenly, and synthetic gasoline can also be produced. Other technological conditions are with embodiment 1.

Abstract

The invention relates to the new energy resources field. The invention is characterized in that plant fibers are required to have a pulverizing diameter width of 2 to 0.5 mm and are in the shape of cotton wool by material pulverized process, and are hydrolyzed, fermented, filtrated and distilled to prepare ethanol; the ratio of the hydrolyzed material added into fermenting enzyme is 1000:25; the formulation variables of raw material preparing fermenting enzyme, namely, pennisetum alopecuroides, chinese yam, wheat malt and barley malt occupy (60-8) to (10-20) to (5-15) to (5-15), and the pennisetum alopecuroides is a whole crop fresh product; the formulation variables of raw material preparing intermediate, namely, alcohol, acetone and benzene occupy 30 to 30 to 40, which can be prepared to use after being mixed; the raw material ratio of the synthesis procedures, namely, alcohol, intermediate, solvent oil and oxydol occupy 50 to 20 to 25 to 5, and which can produce finished product synthetic petroleum after being evenly agitated and mixed. Products accord the national petroleum standard after being detected, raw material source is wide, the product cost is low, the economic benefit is high, and the invention is practically a new way of relieving the shortage of fuel oil.

Description

technical field [0001] The present invention uses plant straws to prepare ethanol and synthetic gasoline and relates to the field of new energy. Specifically, waste plant straws are used as main raw materials to produce ethanol, and ethanol is used to produce intermediates, and then ethanol and intermediates are used as main Raw materials to synthesize fuel oil in short supply. Background technique [0002] At present, the content of alcohol raw materials in synthetic fuel oil is only about 20%, and the energy-saving effect is not obvious; the raw material of ethanol in synthetic gasoline is corn, which leads to a tight market for corn and a shortage of feed raw materials for poultry and livestock. Contents of the invention [0003] The purpose of the present invention is to address the aforementioned defects, and develop a new method for preparing synthetic gasoline, using plant straw, through crushing, soaking, hydrolysis, fermentation, distillation, and synthesis proces...
