Wherein, R is saturations or undersaturated straight chain or the alkyl with branch, the carbon atom number of the alkyl 1~20 it
Between;
It is 50 DEG C~90 DEG C that graininess, which is acidified, and carries out loaded modified temperature in recessed soil addition ionic liquid, loaded modified
Time be 0.5~2h, it is loaded modified after drying temperature be 100 DEG C~160 DEG C, 3.0~5.0h of drying time,
Ingredient proportion is controlled, the content 1%~15% (wt) of resulting recessed soil matrix catalyst intermediate ion liquid, particle are made
The recessed native content of shape acidification is 85%~99% (wt).
The present invention also provides a kind of recessed soil matrix catalyst using above method preparation is micro- in removing reformed oil
Measure the application of alkene, concrete application are as follows: recessed soil matrix catalyst is put into tubular continuous reactor, reformed oil is passed through, into
Row tubular type successive reaction, tubular continuous reactor exported product are the reformed oil for removing alkene,
Wherein, the pressure of tubular type successive reaction be 0.5MPa~3MPa, air speed 0.5h-1~5h-1, reaction temperature 130
DEG C~180 DEG C.
The beneficial effects of the present invention are: first by ionic liquid loaded on acidified attapulgite, then will
The loaded catalyst arrived is used for the processing of reformed oil, and loaded catalyst has a small amount of alkene in reformed oil
Very strong removing selectivity, therefore not will lead to the reduction of the effective component aromatic hydrocarbons of reformed oil in treatment process.
