This study uses the Eulerian-Lagrangian multiphase particle-in-cell (MP-PIC) approach, adopted in computational particle fluid dynamics (CPFD) code, Barracuda VR®, to simulate a cold-flow dual-circulating fluidized bed. The hydrodynamics is simulated using novel segregated which experimental solids circulation rate specified as an input parameter. CPFD predictions of pressures and concentration...

Lewis acidic zeolites are used to synthesize unsaturated dicarboxylic acid esters via aldol condensation of keto esters. Hafnium-containing BEA (Hf-BEA) zeolites catalyze the condensation of ethyl pyruvate into diethyl 2methyl-4-oxopent-2-enedioate and diethyl 2-methylene-4oxopentanedioate (an itaconic acid ester analogue) with a selectivity of ca. 80% at ca. 60% conversion in a packed-bed reac...

We analyzed the effects of gravitational unloading on muscular fatigability and the effectiveness of resistive vibration exercise to counteract these changes. Changes in knee extensor fatigability as a consequence of 8 weeks of horizontal bedrest with or without daily resistive vibration exercise were evaluated in 17 healthy male volunteers. Bedrest increased fatigability (% decrease in maximal...

This study focused on the elimination of chlorobenzene by dual adsorption/catalytic oxidation over activated carbon fibers (ACFs) loaded with transition metal oxides (TMOs). The TMOs were successfully ACFs incipient wetness impregnation method, which has advantages easy preparation, low cost, and size uniformity. removal effects for (CB) investigated pristine TMOs@ACFs in a fix-bed reactor. exp...

Converting rice husk into energy is a promising method of generating renewable and reducing greenhouse gas emissions. In this research hush considered as biomass fuel. The characteristics gasification were investigated at an Equivalence Ratio (ER) 0.25–0.38 gasifier temperature 750-870°C in 20 tons per day (TPD) using steam explosion process fluidized bed system. Different operation conditions,...
