Hydrocarbon By Isomerisation TRIZ Cases

UZM-54 zeolite catalyst reduces xylene loss to 0.2% while maintaining para-xylene production efficiency.

Acidic sulfonated polymeric membrane enables xylene isomerization at 20 to 200°C, reducing energy consumption compared to high-temperature processes.

Phase-controlled EU-2 zeolite support overcomes limited isomerization selectivity in conventional hydrodewaxing, boosting lubricant base oil quality.

Multiple stabilization zones and chilling steps recover C4 hydrocarbons while removing chlorides without extra stripping units.

A deisohexanizer paired with a selective permeation membrane recovers normal hexane from bottoms streams for isomerization reactor recycle.

UZM-29 zeolites maintain structural integrity at 400°C, resolving the contradiction between catalyst performance consistency and high-temperature operation.

Silicon-based mesostructured catalyst enables simultaneous dehydration and skeletal isomerization of C4 monoalcohols.

A process separates paraffins from butenes using extractive distillation before isomerization and metathesis with ethylene to produce propylene.

Isomerizing C9 aromatics into trimethylbenzenes via bifunctional catalysis avoids carbon loss from dealkylation.

Metathesis of fatty acid esters with alkenes followed by microbial oxidation yields renewable diacids.

Transition metal catalysts and acid washed clay convert alpha olefins to internal olefins while removing oligomers that reduce ASA sizing efficiency.

Converts low-value C5 olefins into higher value butenes and propylene through isomerization and metathesis, addressing decreasing C5 demand.
