The exploration of highly efficient catalysts based on nano-sized Ti-rich titanosilicate zeolites with controllable active titanium species is great importance in zeolite catalytic reactions. Herein, we reported an and facile synthesis TS-1 (MFI) by replacing tetrabutyl orthotitanate (TBOT) tetramer (TBOT-tetramer) as the source. introduced TBOT-tetramer slowed down crystallization process, acc...

The stereochemistry of the desulfurization products of chiral natural and synthetic 3,6-epidithiodiketopiperazines (ETPs) is specified inconsistently in the literature. Qualitative mechanisms have been put forward to explain apparently divergent stereochemical pathways, but the quantitative feasibility of such mechanistic pathways has not been assessed. We report a computational study revealing...

Several organosulfur compounds are present in the crude oil, and are required to be removed before its processing into transport fuel. For this reason, biodesulfurization of thiophenic compounds has been studied extensively. However, studies on the sulfide compounds are scarce. In this paper, we describe desulfurization of a model sulfidic compound, dibenzyl sulfide (DBS) by an isolated Gordoni...

Wettability is an important factor affecting the performance of catalytic oxidative desulfurization. In order to develop efficient catalyst for extractive coupled desulfurization (ECODS) fuel oil by H2O2 and acetonitrile, a novel family imidazole-based polyoxometalate dicationic ionic liquids (POM-DILs) [Cn(MIM)2]PW12O40 (n = 2, 4, 6) was synthesized modifying phosphotungstic acid (H3PW12O40) w...

In the oil and gas production process, apart from hydrocarbons, a number of impurities are produced, including CO2 sulfur in various concentrations, depending on conditions characteristics reservoir location where is located. To process removal condensate, common technology HDS (Hydrodesulfurization). However, with requirements such as high temperature, pressure, intensive hydrogen consumption,...
