SAPO-5 shows good activity and selectivity for cumene synthesis by alkylation
of benzene with isopropanol.
3] catalyst, however, the PS-graft-POE copolymer formed via Friedel-Crafts alkylation
reaction serves as a compatibilizer that concentrated at the interface between PS and POE, and promotes adhesion between the two uncompatibilized polymers, as shown in Fig.
A linear relationship was obtained when the Taft equation was applied to the alkylation
In the four construction unit ionic liquid alkylation
project joint design review will be from the headquarters of the Ministry of Development Planning, Refining, Engineering, Department of Materials, Department of Central, external experts, Sinopec Engineering Construction Company, More than 160 representatives from the University of Petroleum, various construction units and design institutes have carefully reviewed the submissions and formed a total of 275 review opinions.
Basic engineering and process technology were being supplied by Scientific Design (US) for the ethylene glycol and ethylene oxide units, Himont (US) for the polypropylene unit, BP Chemicals (UK) for the polyethylene unit, TEC (Japan) for the SBR, PBR, ABS and SAN units, TEC/Nippon Zeon (Japan) for the butadiene unit, Institut Francais du Petrole for the butene-1 and MTBE units, and UOP (US) for the aromatics plant and the alkylation
and polymer gasoline units.
Ionic liquids alkylation
offers a compelling economic solution compared to conventional liquid acid technologies while delivering the same yields and high levels of octane, said Mike Millard, vice president and general manager of Honeywell UOPs Process Technology and Equipment business.
The unit will be utilising CB&I's advanced CDAlky sulfuric acid alkylation
technology for production of 23 000 bpd of alkylate based on 100% C5 olefin feedstock and marks CB&I's first US license for the technology.
CB&I today announced it has been awarded the license and engineering design of a grassroots alkylation
unit by PT Pertamina (Persero).
But an abundance of cheap butane has refiners on the US Gulf Coast looking seriously at expanding or even building new alkylation
plants that use butane derivatives to create valuable high octane gasoline blendstocks.
The complex was to have an aromatics plant with a capacity of 115,000 t/y of benzene, 20,000 t/y of toluene, plus a 100,000 t/y alkylation
unit and a 30,000 t/y catalytic condensation (polymer gasoline) unit.
