abstract = {A new reactor for process intensification using sorption enhanced reaction is described. The novelty compared with most experimental work is that a continuous sorbent feeding (CSF) provides a steady state operation. The sorbent increases the reaction rate of a reversible reaction. The reactor is based on the phenomena of segregation of solids in fluidized bed reactors by using a catalyst and a sorbent. Under certain conditions of density and particle size, the two solids segregate and the sorbent may be removed from the bed with only a small content of catalyst. The system has been experimentally tested in the hydrogenation of CO2 to methanol, using a zeolite as sorbent. A significant increase in CO2 conversion was achieved compared with the same reactor without sorbent.},

abstract = {Lindane is an organochlorine pesticide, that has caused contamination of soil, water and air. This paper studies catalytic hydrodechlorination as a possible solution to the lindane problem in water streams. Several catalysts were tested. The effects of mass transfer and temperature was studied for a Ni-based and a Pt-based catalysts. A Ni-supported and a Pt-supported catalyst gave good results, but the best catalyst was Pd supported on active carbon, which provided 99% conversion in a few minutes at room temperature. Additional tests allow to discard adsorption instead of a catalytic effect. The amount of hexachlorocyclohexane compounds remaining as adsorbed on the catalyst surface was negligible.},

abstract = {Silica aerogels, characterized by their high porosity and substantial specific surface area, are suitable for applications as catalysts or catalyst supports. The simultaneous attainment of a substantial specific surface area and robust mechanical properties in aerogel materials remains a formidable challenge in material synthesis. Spherical FePOx/SiO2 aerogel materials were synthesized employing a combination of heating reflux, the sol-gel technique, and supercritical ethanol drying. These composites demonstrate an exceptional specific surface area, uniformly dispersed active components, shape controllability, and superior mechanical strength. A noteworthy enhancement in both specific surface area (1175 m2/g) and compressive modulus (7.56 MPa) surpasses many findings reported in extant literature. Under conditions of a reaction temperature at 650 °C and a flow rate of 97.5 mL/min, the HCHO selectivity and yield for 4 wt% FePOx/SiO2 aerogel were 18.3 and 4.2 times, respectively, higher than those of 4 wt% FePOx/SiO2 particles. These composites manifest significant selectivity towards the direct catalytic oxidation of CH4 to HCHO.},
