Resumen
Cu/ZnO/Al2O3 catalysts were prepared for online methanol steam reforming (MSR) using a conventional sol–gel method in this study. The optimal preparation conditions, including the calcination temperature, Cu loading, molar ratio of citric acid to metal ions (CA/M), and pH, were investigated. CZA50 exhibited the highest MSR activity among all catalysts. It was prepared at a calcination temperature of 350 °C; Cu, Zn, and Al molar fractions of 50%, 30%, and 20%; CA/M of 1.5; and without adjusting pH. Furthermore, a modified sol–gel method was proposed to enhance the mechanical strength of Cu/ZnO/

Resumen
Pozzolans are siliceous or aluminous materials which possess little or no cementing property but chemically react with calcium hydroxide at ordinary temperature to form compounds possessing cementitious properties. There is paucity of information on the pozzolanicity of Cocoa Pod Ash (CPA). Hence, this study investigated the pozzolanicity of CPA. Cocoa pods were obtained from selected farms in Egba Odeda, Ogun State Nigeria. The Cocoa pods were washed, sundried and calcinated to ashes in a furnace between 600° C to 1000° C at Science Laboratory Technology Department, Federal Polytechnic Ilaro,

High amounts of carbon as well as chromium, titanium and zirconium favour the formation of stable carbides, which guarantee high creep strength even at the upper temperature limit. The excellent creep strength is combined with high oxidation resistance, because 2 % aluminium in presence of about 25 % chromium in the alloy are sufficient to provide for alumina scale formation, so that cyclic oxidation

Resumen
Abstract This paper is a “high temperature” sequel to previous investigations of four specialty inorganic coatings said to prevent corrosion under wet insulation conditions with temperature cycling both in the CUI range of -5°C to 175°C and up to ca 400°C. In the present work, two of the specialty coatings have been tested again, viz a one coat system of a titanium modified inorganic copolymer (TMIC) with aluminum flake pigmentation and a two coat system of a high performance modified silicone with MIO (Coating A). Carbon and stainless steel pipes were abrasive blasted to SSPC-SP10 near white

Resumen
Abstract Corrosion under insulation (CUI) is a costly and complex problem for industry to contend with successfully. This paper describes a suite of accelerated laboratory tests undertaken in part to evaluate some of the claims made for engineered coatings touted to possess high heat resistance to 400°C and simultaneous anticorrosion properties. Thermal spray aluminum (TSA) was used as the benchmark to assess the coating performance of three liquid-applied coatings in cyclic temperature and corrosive microenvironments. All four coatings were applied to carbon steel pipe. The liquid-applied coa

Prolonged application may result in P accumulation up to levels that impair plant nutrition, increase P loss, and promote eutrophication in downstream waters. This study aims to shed light on the RW- and BS-P forms in soils and to follow the processes that determine P reactivity, solu
