“…In this way zeolites ITQ-2 [20,98], , ITQ-18 [101] and ITQ-20 [102] have been prepared. The resultant zeolitic materials showed very high accessible surface areas and interesting catalytic properties for a large number of acid catalyzed reactions [103][104][105][106][107][108][109][110][111].

“…Sanati et al and Corma et al discussed the use of various catalysts for alkene oligomerization. In contrast to the rich data available on long- and short-chain alkenes, published data on C 5 –C 6 alkene oligomerization is scarce.…”

“…The catalyst is usually optimized taking into consideration the type of alkene to be oligomerized. The addition of a mesoporous catalyst system is needed in processing higher carbon number alkenes . As the porosity of the zeolite catalyst is increased, the degree of oligomer branching is also increased .…”

“…Corma et al discussed the importance of intracrystalline zeolite diffusion paths for oligomer products as a function of the density of Brønsted acid sites, crystal size, and crystallite mesopores. To achieve better conversion and lower deactivation, the authors suggested having additional mesoporosity and additional Brønsted acid sites.…”

Catalytic Upgrading of Light Naphtha to Gasoline Blending Components: A Mini Review

et al. 2019

View full text Add to dashboard Cite

The upgrading of light naphtha (C5–C6 stream) to gasoline blending components has been the subject of intensive research at both academic and industrial laboratories. The combination of high volatility and low-octane number has made this stream surplus at many refineries worldwide. This review presents the latest developments in selected catalytic upgrading processes and a brief discussion on the reaction mechanism and reactor models. A majority of the review falls within the development of catalysts for n-hexane isomerization to hydrocarbon isomers with a high octane number. There are three types of isomerization catalysts that include Pt/Al2O3–Cl, Pt/SO4–ZrO2, and Pt/zeolite. Efforts are ongoing to improve the catalyst performance for higher selectivity and catalyst lifetime. Very little work has been published on the conversion of n-pentane mainly as a result of its low activity and the limited options available for its transformation to gasoline blending components. Other approaches discussed in the review include dimerization and oligomerization of C5–C6 alkenes and methylative homologation. The review covers literature published during the period of 2000–2018.

“…Oligomerization of light olefins is of considerable academic and industrial interest because it is one of the major processes for production of higher olefins, which are feed stocks for plastics, plasticizers, lubricants, detergents, oil additives, fatty acids, etc. , Olefin oligomerization has also attracted more and more attention for the production of environmentally friendly and sulfur-free transportation liquid fuels including gasoline and diesel fuels, − especially when light olefins can be produced from clean and renewable sources including biomass through the processes such as conversion of bioethanol and the above-mentioned biomass conversion process…”

As part of a new approach to convert biomass to liquid fuels, we investigated the effects of alkali treatment on the property and performance of HZSM-5 catalyst for oligomerization of biomass-derived ethylene under atmospheric pressure. The characterization results showed that alkali treatment led to an increase in the total and mesopore volumes but a decrease in the surface area and micropore volume. When NaOH concentration was low (<0.5 M), the ZSM-5 structure was largely preserved with the increase in the mesopores and acidity, while higher NaOH concentration can severely destroy the zeolite structure, resulting in a significant reduction in the micropores and acidity. The ethylene oligomerization results showed that not only the ethylene conversion and the liquid yield increased but also the catalyst stability was improved after proper NaOH treatment. The relationship between the structure and performance has then been discussed.
