The used aqueous alcohols of the utility model can be methyl alcohol, ethanol, butanols oil or fusel wet goods.With methyl alcohol is that example illustrates the reaction that it carries out in catalyst cracker:
Wherein based on reaction (1), with the difference of catalyzer and the change of reaction region, may generate methane, dimethyl ether, formaldehyde etc., in course of reaction, main resultant is hydrogen, carbon monoxide and methane.
Carry out for guaranteeing the upgrading successful reaction, it is necessary adding an amount of water in alcohols feedstock, this be because: alcohols cracking (still being example with methyl alcohol) is the reaction that volume increases, add the dividing potential drop that water can reduce raw alcohol, thereby the carrying out that helps lytic response, the existence of water can also suppress to generate paying of dimethyl ether and react generation, makes a small amount of carbon deposit generation water gas reaction:
Help removing the carbon deposit of catalyst surface, prevent the reduction of catalyst activity, the resultant of clear charcoal reaction is the purpose product just.The existence of water vapour simultaneously can make the carbon monoxide of generation become carbon dioxide and its reaction of hydrogen is:
Therefore, adding an amount of water is absolutely necessary.
Catalyzer is the another key that guarantees that lytic response is carried out smoothly, and the lytic response catalyzer is different with the difference of used alcohol.But all should meet inexpensive, be easy to get, the requirement of wear-resisting, efficient and long service life.
