Linear Alkyl Benzene Import In Pakistan.

Pacol-HF process of UOP:

Pacol-HF process consists of two parts: Molex process for separating n-alkanes from kerosene fractions; Pacol-HF process for dehydrogenation and alkylation of n-alkanes. In order to improve the yield of the product, the molar benzene - ene ratio and volume acid-hydrocarbon ratio of Pacol-HF are required to be 5-12:1 and 1.5-2:1.

The product obtained of Linear Alkyl Benzene Iran by this process has high activity, light color, suitable for the preparation of high-end detergent products, and high production efficiency. For example, Ethylene-Vinyl Acetate the recovery rate of Molex can reach 97%, and the purity of n-alkanes is more than 99%. The selectivity of olefin in Pocal process is up to 90%. The alkene conversion rate of alkylation step is close to 100%.

The Molex method of Linear Alkyl Benzene Iocl is a liquid-phase adsorption and separation process of n-alkanes from hydrocarbon mixtures by Molecular Sieve. The process is suitable for wide fractions and high boiling point feedstocks ranging from light to heavy hydrocarbons. The adsorption and desorption can be carried out under the same temperature and pressure, and the rotary valve is used to make the adsorption and desorption process continuous. The normal alkane and isomeric alkane were separated by a simulated moving bed with 5a molecular sieve in a fixed bed. The adsorbed n-alkanes were washed with a mixture of desorption agents 60% n-pentane and 40% iso-octane to make the n-alkanes desorbed out, and the desorption agents were recovered by distillation and recycled.

The process of Pocal n-alkane dehydrogenation is to prepare single olefin with high purity n-alkane as raw material through platinum dehydrogenation catalyst, which is the core process of straight-chain alkylbenzene preparation by dehydrogenation method and plays a decisive role in the quality, consumption, cost of alkylbenzene products and economic benefits of the whole unit. On the platinum dehydrogenation catalyst, the main reaction of straight alkanes dehydrogenation to single olefin, as well as the deep dehydrogenation reaction, isomerization reaction, aromatization reaction, cracking reaction, coking reaction and so on, thus constituting a very complex reaction system. In the deep dehydrogenation reaction, the single olefin generated by the main reaction continues to dehydrogenate to diene or polyolefin, pvc resin are also reactions catalyzed by metal active centers.
