In this regard, biodiesel production is one of the gorgeous solutions for the research community. Contrary to the benefits, the high cost of the biodiesel is the main disadvantage, greatly reliant on the feedstock. In this sense, wild olive oil was explored for the first time as a suitable and novel feedstock for biodiesel technology development.

Selection of appropriate carrier is one of the most important measures to improve catalytic activity as well as anti-poisoning capability of SCR catalyst. Manganese oxide-cerium oxide supported on traditional titanium dioxide (denoted as MnCe/TiO<sub>2</sub>) and titanate nanotubes (denoted as MnCe/TiNTs) were prepared by impregnation method and their catalytic activities towards NH<sub>3</sub>-SCR of NO were evaluated in flue gas with or without SO<sub>2</sub> & H<sub>2</sub>O.

Supporting MnO<sub><i>x</i></sub>–CeO<sub>2</sub> composite on TiNTs not only enhances the catalytic activity at low temperature, but also improves N<sub>2</sub> selectivity and widens active temperature window of catalyst. The main reason is the large specific surface area as well as the unique hollow tubular structure of TiNTs facilitates high dispersion of catalytic active components on the inner and outer walls of TiNTs, which enriches surface acid sites and surface reactive oxygen species to fulfill low temperature SCR reaction cycle. Moreover, TiNTs significantly enhances the SO<sub>2</sub> & H<sub>2</sub>O tolerance of catalyst, for the competitive adsorption between SO<sub>2</sub>, H<sub>2</sub>O and reactants is alleviated and the deposition of ammonium sulphate or ammonium bisulphate becomes more difficult on MnCe/TiNTs catalyst. Besides, the confinement effect of TiNTs makes partial toxicants be trapped inside the tubular channel of TiNTs.
