“…Similar comparisons have previously been made for alkylates produced from propylene and C4 olefins (Li et al., 1970a,b;Durrett et al, 1963). Considerably more information relative to the use of pentenes is however reported here.…”

“…Tentative divisions between C9 and C10, C10 and Cn, etc. isoparaffins are based on results of Durrett et al (1963) and the available boiling points of the n-paraffins. The hydrocarbon analyses are reported here on a weight basis.…”

“…Twelve peaks which are thought to be C9 isoparaffins were detected on the chromatographs. Several of these peaks were identified using pure samples of several C9 isoparaffins and the results of Durrett et al (1963). The first four C9 peaks were 2,2,5-TMH, 2,2,4-TMH, 2,4,4-TMH, and 2,3,5-TMH.…”

“…Schmerling (1955) reports that when isobutane is alkylated with 2-pentenes in the presence of sulfuric acid at 10 °C, the alkylate contains 55-60 wt % C9 isoparaffins and 11-15 wt % isopentane. Cupit et al (1961) and Durrett et al (1963) reported similar results for alkylations with 2-pentenes, but they indicate that alkylations with 2methylbutene-2 (2-MB2) and 2-methylbutene-l result in greater production of isopentane, C6 and C7 isoparaffins, and trimethylpentanes (TMP's). In the latter alkylations, fewer C9 isoparaffins were produced.…”

“…Os modelos matemáticos para unidade de alquilação comercializados atualmente se utilizam dos dados das plantas industriais para os quais os modelos serão aplicados para estimar seus parâmetros internos e, dessa maneira, representar da melhor forma possível a unidade em questão. Apesar de representarem adequadamente o processo, esses modelos têm limitações, tais como apresentar o alquilado como soma de pseudo componentes, mesmo sendo sua composição amplamente conhecida e discutida (ALBRIGTH e WOOD, 1997;DURRETT et al, 1963;CUPIT et al, 1961) e facilmente medida por cromatografia. A análise cromatográfica do alquilado fornece importantes informações a respeito do mecanismo de reação que está predominando no reator, facilitando a identificação e solução de problemas operacionais.…”

Alkylation is the process which light hydrocarbons (like butenes and iso-bute) are transformed into heavier hydrocarbons, called alkylate. The alkylate demand as a gasoline component has been growing since the middle 90's, mostly due to more severe quality requirements for gasoline. This work proposes a mathematical model that accounts for the main chemical reactions for a HF Alkylation Unit. The alkylate yield and quality, described by its composition, are also represented as well. This model as based on mass and energy balances for the alkylation reactor, using the most accepted kinetic mechanism available at literature. The model constants were estimated by non-linear regression with available data from literature. The model validation was performed comparing the simulation results with data collected at an industrial Alkylation unit at Cubatão, Brazil, without further parameter adjustment. The results show a good model response for the consumption of reagents and alky yield. The model, however, underpredicts the yield of heavier fractions.

Alkylate gasoline produced by the reaction of isobutane with light olefins is a high value blending component of the gasoline pool owing to its high octane (both RON and MON) and its clean burning properties. In the first part of this article, the main aspects of the actual alkylation technology based on H 2 SO 4 or HF liquid‐acid catalysts are described, including the proposed reaction mechanisms, the influence of operating variables on product quality, and a brief description of the commercial sulfuric and hydrofluoric alkylation processes. Special emphasis is given in this part to the recent developments directed to improve the efficiency of the actual liquid‐acid alkylation processes, as well as to reduce the potential dangers associated with the use of H 2 SO 4 and HF catalysts. In the second part of the article, the latest achievements in the use of environmental friendly solid acids as a desirable alternative to the liquid‐acid alkylation technology are reviewed. The different solid acids studied as potential alkylation catalysts include supported Brönsted and Lewis acids, exchange resins and composites, zeolites, sulfated metal oxides, and heteropolyacids and their salts. Their catalytic activity, selectivity, and stability in relation to the isobutane alkylation reaction are discussed. Finally, different reactor configurations and processes proposed for solid acid alkylation are also addressed.
