Embodiment 1

[0016] Take 100kg distiller's grains, wash them with water for 2 hours, separate them, press filter the distiller's residues, and carry out air-drying under a pressure of 0.5Mpa. The dried residues are pulverized with a hammer mill, passed through a 100-mesh sieve, and added equivalent to 5% by weight of Actinobacillus succinicum was fermented for 72 hours, then press-filtered, decolorized with activated carbon, extracted (extracted with a mixed reagent of trioctylamine and n-octanol at a volume ratio of 3:1), and the fermentation broth was mixed with The volume ratio of the extractant is 1:0.9, the extraction temperature is 35° C., and the extraction time is 50 minutes to obtain succinic acid. The separated rice husks were burned, crushed through a 100-mesh sieve, washed with sulfuric acid of pH 1, filtered, alkali-dissolved with 4mol / L sodium hydroxide, suction filtered, added 0.5% EDTA chelating agent for aging for 5 hours, and Aged for 1.5 hours, washed, and spray-dried to...

Embodiment 2

[0018] A method for comprehensively utilizing distiller's grains to produce high-performance white carbon black and succinic acid. The distiller's grains fermented with liquor are used as raw materials, and the distiller's grains are washed with water to separate the grains from the rice husk; , crushed through 80-100 mesh (for example, 80 mesh, 90 mesh, 100 mesh), fermented with Actinobacillus succinate, then press-filtered, then decolorized with activated carbon, and extracted to obtain succinic acid; Combustion, crushing rice husk ash through 80-100 mesh (for example, 80 mesh, 90 mesh, 100 mesh) sieve, pickling, filtering, alkali dissolution, suction filtration, adding chelating agent for aging, aging, washing, and spray drying to obtain High performance silica.

[0019] Airflow drying is carried out under the condition of 0.3-0.5Mpa (eg 0.3Mpa, 0.4 Mpa, 0.5 Mpa).

[0020] When preparing succinic acid, the amount of Actinobacillus succinate is 2%-8% (for example 2%, 5%, 8%...

Abstract

The invention discloses a method for producing high-performance white carbon black and succinic acid by comprehensively utilizing white spirit lees, which comprises the following steps of: taking lees after fermenting white spirit as a raw material, and separating lees residues and rice husks after carrying out water washing; taking the lees residues for carrying out filter pressing, then carrying out airflow drying, pulverizing, sieving by a sieve with 80 to 100 meshes, fermenting by using actinobacillus succinogenes, carrying out filter pressing again, afterwards discoloring by active carbon and extracting so as to obtain succinic acid; and taking the rice husks after separating, burning, pulverizing the ashes of the rice husks, sieving by a sieve with 80 to 100 meshes, carrying out acid washing, filtering, carrying out alkali dissolving, leaching, adding a chelating agent for curing, aging, washing and carrying out spray drying so as to obtain high-performance white carbon black. According to the method for producing the high-performance white carbon black and the succinic acid by comprehensively utilizing the white spirit lees, industrial solid waste white spirit lees are taken as the raw material, high and new technologies, such as a biological fermenting technology and the like, and an advanced process for the full utilization and the zero discharge of products generatedin procedures are adopted in an integrated way, and products, such as the high-performance white carbon black, the succinic acid and the like, are developed. The method for producing the high-performance white carbon black and the succinic acid by comprehensively utilizing the white spirit lees has higher popularization value.

Description

technical field [0001] The invention relates to a method for producing white carbon black and succinic acid by using distiller's grains. Background technique [0002] Distiller's grains are the waste residues produced by the fermentation of liquor production. Currently, they are only used as feed for livestock. The utilization rate and added value are low, and it will occupy the site. In summer, it will produce peculiar smell and pollute the environment. Contents of the invention [0003] The object of the present invention is to provide a method for producing high-performance white carbon black and succinic acid by comprehensively utilizing distiller's grains with simple process and easy operation. [0004] Technical solution of the present invention is: [0005] A method for comprehensively utilizing distiller's grains to produce high-performance white carbon black and succinic acid is characterized in that: the distiller's grains fermented with liquor are used as raw m...
