Estimating the term…
A beta zeolite catalyst for the preparation of a BTEX (benzene, toluene, ethylbenzene, xylene) mixture from polyaromatic hydrocarbons and a preparation method of the same are disclosed. The beta zeolite catalyst demonstrates high conversion of polyaromatic hydrocarbons and high BTEX production yield by containing optimum contents of the group VIB metals and cocatalysts, so that it can be effectively used as a beta zeolite catalyst for the production of BTEX.
A beta zeolite catalyst for preparing BTEX from polyaromatic hydrocarbons comprising 1-methylnaphthalene, which comprises a beta zeolite, tungsten, and one cocatalyst selected from the group consisting of phosphorus and aluminum, wherein a content of the tungsten is about 1.1 mmol in 1 g of the beta zeolite catalyst, and a content of the cocatalyst is 0.18-0.37 mmol in 1 g of the beta zeolite catalyst.
