Embodiment 1

[0020] Take 100 as the base rate, weigh 500kg of grass, 50kg of lime, and 700kg of clean water according to the ratio of raw, semi-dry or dry grass to lime and clean water of 5:0.5:7, and put the grass in the soaking tank in turn. Soak to remove alkali for 10 days. Thereafter, the grasses are taken out, cleaned and put into a pulper to be pulverized and refined into pulpy raw meal.

[0021] Experiments have proved that the pulpy grass-like 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.

[0022] Weigh the crushed grass pulp raw meal according to raw meal: alcohol koji: clean water = 100: 0.9: 300 (when the temperature is higher than 30º, add 0.9 kg of koji to 300° of water) and weigh 100 kg of raw meal, 0.9 kg of alcohol koji, and 300 kg of purified water And put it into a fermentation tank or pool, then use a mixer or manually stir the mash evenly, and seal the t...

Embodiment 2

[0026] Take 100 as the base rate, weigh 600kg of grass, 60kg of lime, and 800kg of clean water according to the ratio of raw, semi-dry or dry grass, lime, and clean water to 6:0.6:8, and put them into the soaking tank in turn. Soak to remove alkali for 11 days. Thereafter, the grasses are taken out, cleaned and put into a pulper to be pulverized and refined into pulpy raw meal.

[0027] Experiments have proved that the pulpy grass-like 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.

[0028] Weigh the crushed grass pulp raw meal according to raw meal: alcohol koji: clean water = 100: 1: 290 (when the temperature is lower than 30°, add water 290 to koji 1) and weigh 100 kg of raw meal, 1 kg of alcohol koji, and 290 kg of purified water And 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...

Embodiment 3

[0032] Take 100 as the base rate, weigh 700kg of grass, 70kg of lime, and 900kg of clean water according to the ratio of raw, semi-dry or dry grass, lime, and clean water to 7:0.7:9, and put them into the soaking tank in turn. Soak to remove alkali for 12 days. Thereafter, the grasses are taken out, cleaned and put into a pulper to be pulverized and refined into pulpy raw meal.

[0033] Experiments have proved that the pulpy grass-like 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.

[0034] The pulverized grass pulp raw meal is raw meal: alcohol koji: water = 100: 1; 1: 280 (when the temperature is lower than 20°, use koji 1.1 and water 280), and weigh 100 of raw meal, 1.1 kg of alcohol koji, Put 280kg of clean water into a fermentation tank or pool, then use a mixer or manually stir the mash evenly, and seal the tank or pool mouth for anaerobic fermentation.

Abstract

The invention relates to a new efficient alcohol preparation process through liquid-state fermentation of a grass-based raw material. According to the process, mainly by adopting 100 as the base rate, grass, lime and purified water are weighed according to a ratio of the raw, semi-dried or dried grass to the lime to the purified water of 5-7:0.5-0.7:7-9, the materials are poured to a soaking pool, the grass is subjected to soaking alkali-removing for 10-12 days, the soaked grass is crushed and thinned into a slurry-like raw material, the slurry-like raw material, alcohol koji and purified water are weighed according to a ratio of the slurry-like raw material to the alcohol koji to the purified water of 100:0.9-1.1:280-300 (300 parts of the water is added to 0.9 part of the koji when the temperature is higher than 30 DEG C, 290 parts of the water is added to 1 part of the koji when the temperature is lower than 30 DEG C, and 280 parts of the water is added to 1.1 parts of the koji when the temperature is lower than 20 DEG C) and are poured into a fermentation tank or pool, uniform stirring is performed, anaerobic fermentation is performed, the obtained material is poured into distillation equipment after the mash has a light or deep dark brown color and the fermentation achieves the mature state, distilling is performed, and the obtained ethanol, fuel oil, a combustion-supporting agent, inert gas and the like are subjected to blending mixing according to a certain ratio so as to obtain the grass-based ethanol fuel with characteristics of high quality, high efficiency, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a technology for producing ethanol, in particular to a new process for producing ethanol in a liquid state and high efficiency from grass raw materials. [0002] technical background [0003] 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 grasses and other plant waste resources to develop new energy sources. Contents of the invention [0004] The purpose of the present invention is to provide a kind of advanced comprehensive technology...
