Problems solved by technology

[0002] At present, wastes in the sugar industry, such as molasses and other sugar-containing organic wastes, cannot be effectively utilized in the existing technology, which puts a lot of pressure on enterprises to discharge sewage, and direct discharge will cause great pollution to the environment
Wastes in agriculture, such as: corn stalks containing lignocellulose, sorghum stalks, and Jerusalem artichoke stalks, etc., the existing treatment methods include: field incineration, production of fuel ethanol, etc. The disadvantage of field incineration is that it is an important cause of smog One, the disadvantage of producing fuel ethanol is that the energy density of ethanol is only 60% of that of gasoline, so it is not an ideal liquid energy source

Abstract

The invention relates to a system and method for producing C5-C19 alkyl ketones, belonging to the technical field of biochemical engineering. The system comprises a fermentation apparatus, a product separation and purification device and a chemical catalytic unit, wherein the fermentation apparatus is connected with the chemical catalytic unit through the product separation and purification device; and the product separation and purification device is composed of at least one of a gas stripping purification device, a pervaporation membrane purification device, an adsorptive purification device, a steam penetration purification device, a liquid-liquid extraction purification device, a centrifugal device, a multi-effect evaporation purification device and a rectification purification device. By using the system and method, industrial sugar-containing waste molasses or agricultural waste straws can be converted into C5-C19 long-chain alkyl ketones under the biological catalytic and chemical catalytic actions, and the C5-C19 long-chain alkyl ketones can be used as gasoline, diesel or aviation fuel directly or after being deoxidized.

Description

Technical field [0001] The present invention relates to a production C 5 -C 19 The system and method of alkanone belong to the field of biochemical technology. Background technique [0002] At present, wastes in the sugar industry, such as sugar-containing organic wastes such as molasses, cannot be effectively used in the existing technology, which puts a lot of pressure on enterprises to discharge pollutants, and direct discharge will cause great pollution to the environment. Wastes in agriculture, such as corn stalks, sorghum stalks and Jerusalem artichoke stalks containing lignocellulose. The existing treatment methods include: field burning, production of fuel ethanol, etc. The disadvantage of field burning is that it is an important cause of smog One of the disadvantages of producing fuel ethanol is that the energy density of ethanol is only 60% of gasoline, which is not an ideal liquid energy source. If the sugar-containing organic waste of industry and agriculture can be ...
