Investigation of the reaction network of benzofuran hydrodeoxygenation over sulfided and reduced Ni-Mo/Al2O3 catalysts

The hydrodeoxygenation (HDO) network of benzofuran was studied over alumina-supported Ni-Mo sulfided and reduced catalysts. Over the sulfided catalyst, a major route was observed for the benzofuran HDO network. It started with the hydrogenation of benzofuran to 2,3-dihydrobenzofuran followed by its hydrogenolysis to 2-ethylphenol. However, over the reduced catalysts, an additional route was observed which begins with the hydrogenation of 2,3-dihydrobenzofuran. This route contained a number of other oxygen-containing intermediate species which were not observed over the sulfided catalyst, and hydrocarbon products were formed by this route at significantly lower temperatures. The product distribution for both catalysts was a strong function of temperature and H2S feed concentration where the hydrogenolysis reactions were promoted and the hydrogenation reactions were inhibited by H2S in the feedstream.

Two strategies were reported to prevent the deactivation of Frustrated Lewis pairs (FLPs) in the hydrogenation of terminal alkynes: reducing the Lewis acidity and polymerizing the Lewis acid. A polymeric Lewis acid (P-BPh3) with high stability was designed and synthesized. Excellent conversion (up to 99%) and selectivity can be achieved in the hydrogenation of terminal alkynes catalyzed by P-BPh3. This catalytic system works quite well for different substrates. In addition, the P-BPh3 can be easily recycled.
