The activation energies of benzene and cumene alkylation
reactions as well as the isopropanol dehydration and diisopropyl benzene isomerization reactions compare well with the values for similar reactions on zeolites reported by those investigators and summarized by Palekar and Rajadhyaksha (1986).
3] catalyst, PS-graft-POE copolymer was formed via Friedel-Crafts alkylation
reaction in PS/POE blends.
Figure 5 shows the TG curves of the benzylated PMIA whose degree of alkylation
At present, the Group plans to build 300,000 tons / year ionic liquid alkylation
project in Jiujiang Petrochemical, Anqing Petrochemical, Wuhan Petrochemical and Shanghai Petrochemical respectively.
TPL (Italy) for the ethylene glycol, ethylene oxide, MTBE, alkylation
and polymer gasoline units;
Major process units include a delayed coking unit, a fluid catalytic cracking unit, hydrotreating units, a reformer, an alkylation
unit, and 12,000 barrels per day of lube oil processing capacity.
The unit, which is scheduled to start up at the end of 2013, will use the CDAlky[R] advanced low temperature sulfuric acid alkylation
process to produce 600,000 metric tonnes per annum of alkylate.
Chevron licensed the technology to Honeywell UOP, which will offer the technology under the ISOALKY brand name as an alternative to traditional technologies that use hydrofluoric or sulfuric acids as a liquid alkylation
On February 12, an alkylation
unit involved in gasoline production was shut at the 166,000-barrel-per-day (bpd) Martinez refinery after a sulphuric acid release injured two workers.
for the ABS, SAN and butadiene units; TPL (Italy) for the ethylene glycol, ethylene oxide, MTBE, alkylation
and polymer gasoline units; CTIP (Italy) for the butene unit; and Snamprogetti (Italy) for the aromatics plant.
A major North American refiner has awarded a contract to CB&I for the technology license and engineering design of a new alkylation
process unit to be located on the US Gulf Coast.
unit number 1 and TAME (tertiary amyl methyl ether, used to oxygenate gasoline) are down due to operational problems in Cardon.
