High-density fuel candidates have been synthesized in up to 90%yield from β-pinene, a renewable strained bicyclic compound derived fromwood and plant sources. The process is based on the heterogeneous acidic catalysts Montmorillonite-K10 and Nafion, which promote selective isomerization and dimerization of pinenes under moderate conditions (100 C and atmospheric pressure). Montmorillonite-K10 w...

Intensive development of many industries, including textile, paper or plastic, which consume large amounts water and generate huge wastewater-containing toxic dyes, contribute to pollution the aquatic environment. Among known methods wastewater treatment, adsorption techniques are considered most effective. In present study, weakly basic anion exchangers such as Amberlyst A21, A23 A24 polystyre...

The aim of this study was the evaluation two different procedures for one-pot transformation oil extracted from Citrus limon seeds to a mixture fatty acid methyl esters (FAMEs) and glycerol derivatives application as potential biofuel. Lemon seed obtained by Soxhlet extraction. first procedure realized efficient irreversible transesterification in hexane lipase B Candida antarctica (Novozym 435...

Ion exchange resins have many industrial applications, namely as sorbents and catalysts. In solid-catalyzed reactions, intraparticle reaction-diffusion competition is generally described by effectiveness factors calculated numerically or analytically in the case of isothermal particles simple rate laws. Although robust, numerical calculations can be time-consuming, convergence not always guaran...
