Embodiment Construction

[0016] The raw material that the production method of chemical industry alcohol of the present invention adopts is C 6 Sugar alcohol, which can be commercially available C 6 Sugar alcohols can also use grains as raw materials to produce starch by conventional methods, generate glucose through liquefaction and saccharification, and then produce the C used in the present invention by hydrogenation. 6 sugar alcohol.

[0017] The basic raw material of the present invention is starch. For example, after converting corn into starch milk, it can be directly liquefied and saccharified to produce glucose. Generate glucose solution, and produce liquid C by high-pressure hydrogenation reaction under the action of nickel catalyst 6 Sugar alcohol, under the action of cracking catalyst, C 6 Sugar alcohols are further hydrocracked to generate the chemical alcohols.

[0018] The reaction formula is listed below to illustrate:

[0019] 1. Glucose production

[0020]

[0021] 2. Produc...

Abstract

The invention relates to a method for producing low carbon chemical ethanol from C6 sugar alcohol. Chinese patent disclosed number CN1683293A discloses a method for producing dihydric alcohol and andpolyhydric alcohol by cracking sorbierite. The method comprises the steps of converting the sorbierite into glycol, propanediol and glycerin, but process data and a process route as well as products do not achieve good industrial production requirements. The method mainly adopts a continuous process to hydrocrack the C6 sugar alcohol to generate a low carbon ethanol mixture and finally obtains a single (or mixed) product by separating and refining in alkaline environment, in the presence of a nickel chrome catalyst and at high temperature and high pressure. The process route has the advantages of simple process, easy operation, high yield in unit time and variety of the products; and as the catalyst has different selectivities, the composition rate of the produced products can be substantially adjusted.

Description

technical field [0001] The present invention relates to a kind of by C 6 Water-phase cracking of sugar alcohols to produce chemical alcohols (mainly C 2-4 Dibasic alcohol) method, especially the preparation of C by making starch from corn as raw material 6 Sugar alcohols, which are then hydrocracked to produce C 2-4 The method of chemical alcohol. Background technique [0002] With the continuous development of science and technology, people's consumption of various chemical industry raw materials is also increasing. As a type of chemical raw materials, dihydric alcohols have a particularly large market demand. However, the source of diols on the market now mainly depends on the purification and processing of petroleum, and petroleum, as a non-renewable resource, has been gradually depleted inevitably under continuous use. Moreover, dihydric alcohols (such as propylene glycol and ethylene glycol) produced from petroleum have high cost and serious pollution. In order to ...
