A solid acid alkyl benzene production technology is to produce long chain alkyl benzene by solid acid catalyst to catalyze long chain olefin with benzene to occur alkylation.

Long chain alkyl benzene is an important organic chemical raw material in the field of petrochemical industry。C10-c13 linear alkyl benzene is the main raw material for the production of detergent surfactants。C20-c24 linear alkyl benzene is sulfonated to obtain C20-C24 alkyl benzenesulfonic acid, and high carbon calcium alkyl benzenesulfonic acid is obtained through neutralization process, which is a lubricating oil detergent。C12 branched alkenes are made from tetrapolypropene or tripolybutene and alkylated with benzene to make C12 alkylbenzene, which is mainly used in the production of calcium sulfonate for pesticide emulsifiers。Alkyl benzene produced by alkylation of C16-C18 alkenes with benzene toluene or xylene is the main raw material for oil displacement agent production

In the past, many alkyl benzene products were produced using H2SO4, HF, AlCl3 and other catalysts。But this kind of catalyst all has the problems of equipment corrosion, environment pollution and the difficult of catalyst separation , low product quality and so on. Compared to liquid acid catalysts, solid acid catalyst has high activity and selectivity for a variety of chemical reactions. It is non-toxic and not easy to corrode the equipment. It can be recycled and used, and is environmentally friendly.

1，Adaptable raw material

Alkenes can be derived from ethylene oligomer product , LADH and long chain alkenes over C10 in the Fischer-Tropsch synthesis .
