The performance of a combined catalyst and sorbent material designed for reforming hydrocarbons was evaluated by reacting methane with steam at different temperatures and pressures in a reactor packed with the material. The combined material was in the form of small spherical pellets comprised of a sorbent core of lime encased in a porous shell made largely of sintered alumina that supported a ...

The measurement of total mercury in flue gas based on an economical aluminum matrix sorbent was developed in this paper. A sorbent trap consisted of three tubes was employed to capture Hg from flue gas. Hg trapped on sorbent was transferred into solution by acid leaching and then detected by CVAAS. Hg adsorbed on sorbent was recovered completely by leaching process. The 87.7% recovery of Hg in ...

Mercury emissions from coal fired power plants are generally measured using one of two methods electronic Continuous Emission Monitoring Systems (Hg CEMS) that most commonly use atomic fluorescence, or sorbent traps. Electronic Hg CEMS are often compared against sorbent traps using EPA’s Method 30B Relative Accuracy Test Audit (RATA). Because sorbent traps include mercury contained in the parti...

In the absorption step of the fluorescent treponemal antibody-absorption (FTA-ABS) test (USPHS, 1969) sorbent is used to circumvrent so-called natural antiTreponema pallidum (Tp) reactivity present in a significant proportion of presumed nonsyphilitic individuals (Hunter, Norins, Falcone, and Stout, 1968). It has been postulated that the natural reactivity may be stimulated by nonpathogenic, sa...

Important phenomena were discovered that oxygen-containing expanded graphite an Oxidized OligoGraphene (OOG) obtained after hydrothermic treatment of modified graphite became to be able to interact as sorbent OOG with glycopeptide antibiotics. Introduction. In this work was studied the sorption properties of carbon material as an example of Oxidized OligoGraphene (OOG) concerning glycopeptide a...

Materials that can capture and store CO2 are important. Though CaO is a cheap sorbent, it is inefficient for practical purposes due to sintering and poor diffusion of CO2 through the surface-CaCO3 layer. We have developed a high performance, sintering-resistant CaO-based sorbent by uniformly nanofabricating the CaO nanocrystals on SiO2 microtubes made by organogel templated polymerization.

in this paper, the development of a new potassium carbonateon alumina support sorbent prepared byimpregnating k2co3 with an industrial grade of al2o3 support was investigated. the co2 capturecapacity was measured using real flue gas with 8% co2 and 12% h2o in a fixed-bed reactor at atemperature of 65 °c using breakthrough curves. the developed sorbent showed an adsorptioncapacity of 66.2 mgco2/...

The choice of appropriate reactors and reforming strategies is key to make progresses on scaling up H2 production processes from raw bio-oil. This work compares the performance (conversion, product yields deactivation) packed-bed fluidized-bed (PBR FBR, respectively) using a NiAl2O4 spinel derived catalyst for bio-oil via steam (SR) sorption enhanced SR (SESR, with dolomite capture CO2). experi...

A novel sol-gel hybrid methyltrimethoxysilane-tetraethoxysilane (MTMOS-TEOS) was produced and applied as sorbent for solid phase extraction (SPE). Five selected organophosphorus pesticides (OPPs) were employed as model compounds to evaluate the extraction performance of the synthesized sol-gel organic-inorganic hybrid MTMOS-TEOS. Analysis was performed using gas chromatography-mass spectrometry...
