Para-xylene and fresh acetic acid are mixed with catalyst and recycled acetic acid. The feed stream is pumped to the top of the oxidation reactor while the air enters through the bottom of the reactor. Temperature ...

The residual oil feedstock and process oxygen are preheated to 2450C and pressurized to about 70 bar. Along with recycle soot, and steam diluent, the mixture is passed to the parallel partial oxidation reactors. ...

Sulfuric acid is one of the most important basic chemical products along with ammonia, ethylene and caustic soda. It is used for chemical fertilizers, in the synthesis of various compounds, and also production of such ...

The products which can be produced through saccharification of starch are glucose syrup, dextrose syrup or crystal dextrose, 42% fructose syrup and 55% fructose syrup. These products can also be selectively produced according ...

The UOP Parex process was the first commercial process. It is a continuous process using a fixed bed of adsorbent. All process streams are in the liquid phase at constant temperature in the bed. Feed is introduced ...

Propylene oxide is produced by a two-step process in which isobutane is oxidised using oxygen to tert-butyl hydroperoxide (THP' and the latter is used to oxidise propylene to propylene oxide. Isobutane and oxygen are ...

In this process the hydroperoxide intermediate is used to add an oxygen atom to the propylene. The hydroperoxide itself is made simply by direct oxidation of ethylbenzene with air. The reactors operate at about 3 bar ...

This is a three stage process: prefractionation, hydrotreating, and separation of n-paraffins. Kerosene in the l60-28S'C boiling range is prefractionated to give a stream in the desired range of carbon numbers. This ...

Catalysts consisting of a mixture of alkylaluminium chlorides and alkyltitanium chlorides, plus ethylene, diluent (hexane or cyclohexane), and comonomer (when required), hydrogen (for molecular weight control) are charged ...

The family of styrene resins generally breaks down into polymer styrene and copolymers AS and ABS. All these are thermoplastic resins manufactured with styrene, one of the petrochemicals, as main feedstock. Such styrene ...
