Martínez, C.; Corma Canós, A. (2014). Improved THETA-1 for light olefins oligomerization to diesel: Influence of textural and acidic properties. Topics in Catalysis. 57(6-9):668-682. doi:10.1007/s1124. Abstract.The increase in diesel demand, especially in Europe, and the need for high fuel quality requirements, is forcing refiners to move into additional processes for production of high cetane diesel in order to meet the present market trends. Oligomerization of light olefins into middle distillate range products is a viable option. The fuel produced through this technology is environmentally friendly, free of sulfur and aromatics, and the adequate choice of the heterogeneous catalyst will direct the selectivity towards low branched oligomers, which will result in a high quality product. In this work we show the benefits of combining basic desilication treatments for generation of additional mesoporosity in mono-directional Theta-1 zeolite, with selective acid dealumination steps that restore not only the microporosity to values close to those of the parent samples, but also the total and strong Brønsted acidity. These modified Theta-1 zeolites present an outstanding catalytic behavior for oligomerization of propene, with a largely increased initial activity, a much higher resistance to deactivation with time on stream, and an improved selectivity to products in the diesel fraction, as compared to the original microporous Theta-1.

“…Solid phosphoric acid catalysis has been used industrially since the early 1930s for the production of ''polymer gasoline'' through the oligomerization of light olefins [4]. The SPA catalyst is traditionally produced by mixing phosphoric acid with kieselguhr (diatomaceous earth) followed by extrusion and calcination at high temperature.…”

“…The development of SPA catalysts was pioneered by Egloff and Ipatieff et al during the 1930s [86][87][88][89], primarily for the production of liquid gasoline fractions with high octane numbers by oligomerization and hydrogenation of C 3 -C 5 olefin feedstocks obtained from thermal cracking processes. Later, SPA catalysts were applied for a wide variety of related acid-catalyzed reactions, most of which were described in the patent literature.…”
