. Herein, we present size-controlled SiO2 (silica) nanoparticles in the CLs (catalyst layers) to provide sufficient water to …

combination of NTP with catalyst and adsorbent for better NOx removal efficiency is presented in detail. The removal of NOx from …

cleaning. The utilization of catalyst for hot gas cleaning is one of the most popular technologies for gas cleaning. The … catalyst bed can reform tar molecules to gas on the one hand and destroy or adsorb poisonous gases and particulates on the … other hand, so as to produce clean gas. However, numerous criteria need to be considered to select the suitable catalyst for …

, respectively (microwave power of 400W, methanol/oil molar ratio of 11/1, catalyst amount of 4wt.% and reaction time of 5min). The … catalyst was recycled, and biodiesel yield reduced to 83.6% at the fourth cycle. Fresh and reused sodium silicate catalysts … species resulted in the loss of catalytic activity. The reused catalyst was collected and utilized for hydrothermal …

This work is concerned with the question of why oxidative desulfurization (ODS) catalyst that show good catalytic … gasoline composition on ODS using a phosphotungstic acid/activated carbon (HPW/AC) catalyst with H2O2 were investigated. ODS of …

In this work, the decomposition of hydrogen iodide (HI) over platinum catalyst in a frame work of the development of a … bench-scale Sulfur–Iodine (S–I) cycle is studied. The catalyst Pt/γ-alumina 1.0wt% is prepared by impregnation …–calcination method. The experiments of HI decomposition over the as-prepared catalyst are conducted at the temperature range of 350–550°C …
