New technology for liquid state efficient preparation of ethanol from straw

Abstract

The invention relates to a new technology for liquid state efficient preparation of ethanol from straw. The method consists of: weighing straw, lime and purified water, putting the materials into a soaking pool to perform soaking for alkali removal for 10-12d, then conducting crushing and refining to obtain a slurry raw material, weighing the raw material, an alcohol yeast and purified water and putting the substances into a fermentation tank or pool, stirring the substances evenly to perform anaerobic fermentation, when the fermented liquid turns into light or dark brown and is fermented to maturity, putting the fermented liquid into distillation equipment to conduct heating distillation, and blending the obtained ethanol with fuel oil, a combustion supporting agent, inert gas and the like in proportion, thus obtaining high quality, high efficiency, energy saving and environmental protection straw ethanol fuel.

Description

technical field

[0001] The invention relates to a technology for producing ethanol, in particular to a new technology for producing ethanol in liquid state with rice straw and high efficiency. technical background

[0002] In today's world, energy has become a major strategic resource and decision-making basis for the economic and political development and competition of various countries, and fuel energy is prominent in energy resources, but as the main resource of fuel energy, coal, oil, natural gas and other reserves are extremely limited and easily Exhausted, and the cost of exploitation and use is high and the ecological environment is easily damaged. Therefore, it is particularly important and urgent to further study the utilization of a large number of plant waste resources such as straw to develop new energy sources. Contents of the invention

[0003] The purpose of the present invention is to provide a kind of advanced comprehensive technology, simplified ingredi...

Examples

Embodiment 1

[0019] Take 100 as the base rate, weigh 500kg of straw, 50kg of lime, and 700kg of clean water according to the ratio of raw, semi-dry or dry rice straw to lime and clean water of 5:0.5:7, and put them into the soaking tank in turn to soak the straw to remove alkali 10 days. Thereafter, the straw is pulled out and cleaned, and then put into a pulper to be pulverized and refined into pulpy raw meal.

[0020] Experiments have proved that the pulpy rice straw raw meal softened by alkali removal and crude fiber and pulverized and refined is easier to ferment and has a faster fermentation speed and higher ethanol yield.

[0021] The pulverized rice straw slurry raw meal is raw meal: alcohol koji: clean water = 100: 0.9: 300 (temperature is higher than 30°C, add water 300 with koji 0.9), weigh 100 kg of raw meal, 0.9 kg of alcohol koji, 300 kg of clean water and mix Put it into a fermentation tank or pool, then use a mixer or manually stir the mash evenly, and seal the tank or pool...

Embodiment 2

[0025] Take 100 as the base rate, weigh 600kg of rice straw, 60kg of lime, and 800kg of clean water according to the ratio of raw, semi-dry or dry rice straw to lime and clean water of 6:0.6:8, and put them into the soaking tank in turn to soak the straw to remove alkali 11 days. Thereafter, the straw is pulled out and cleaned, and then put into a pulper to be pulverized and refined into pulpy raw meal.

[0026] Experiments have proved that the pulpy rice straw raw meal softened by alkali removal and crude fiber and pulverized and refined is easier to ferment and has a faster fermentation speed and higher ethanol yield.

[0027] The pulverized rice straw slurry raw meal is raw meal: alcohol koji: clean water = 100: 1: 290 (temperature is lower than 30 °, add water 290 with koji 1), weigh raw meal 100, alcohol koji 1 kg, clean water 290 kg and mix Put it into a fermentation tank or pool, then use a mixer or manually stir the mash evenly, and seal the tank or pool mouth for ana...

[0031] Take 100 as the base rate, weigh 700kg of straw, 70kg of lime, and 900kg of clean water according to the ratio of raw, semi-dry or dry rice straw to lime and clean water as 7:0.7:9, and put them into the soaking tank in turn to soak the straw to remove alkali 12 days. Thereafter, the straw is pulled out and cleaned, and then put into a pulper to be pulverized and refined into pulpy raw meal.

[0032] Experiments have proved that the pulpy rice straw raw meal softened by alkali removal and crude fiber and pulverized and refined is easier to ferment and has a faster fermentation speed and higher ethanol yield.

[0033] The pulverized rice straw pulp raw meal is raw meal: alcohol koji: clean water = 100: 1; 1: 280 (when the temperature is lower than 20°, add water 280 to 1.1 koji) and weigh 100 of the raw meal, 1.1 kg of koji, and clean water. Put 280kg of water into a fermenter or pool, then use a mixer or manually stir the mash evenly, and seal the mouth of the tank or ...
