Abstract:
... The effect of operating conditions and feed characteristics on the performance of the oxidative coupling of methane (OCM) reactor was investigated numerically by analyzing the concentration of the reactants and products along the fluidized-bed reactor. Aimed at modeling such multiphase flow, a two-fluid model based on the kinetic theory of granular flow was applied. The impact of the kinetic model ...

Abstract:
... Directly upgrading natural gas is limited by the stability of its primary component, methane, and process economics. Since the 1980s, oxidative coupling of methane (OCM) has shown potential to produce ethylene and ethane (C₂s). The typical OCM approach catalytically converts methane to C₂ products using molecular oxygen, reducing process efficiency. To overcome this, chemical looping OCM converts ...

Abstract:
... The impact of silica functionalization in determining the performance of polycyanurate networks polymerized from 1,1-bis(4-cyanatophenyl)ethane, known commercially as Primaset LECy, reinforced with modified fumed silica, was elucidated through systematic comparison of the properties of nanocomposite networks in which the silica surface treatment was altered. Three types of surfaces were investigat ...

Abstract:
... Recent increases in shale gas production provide an excellent opportunity for advancements in the energy-efficient separation of natural gas liquids because these are increasingly used as fuel sources and chemical feedstocks. Current fractionation schemes generally involve cryogenic distillation of C₁–C₄ hydrocarbons and are extremely energy-intensive. Here, we describe the first steps toward a lo ...

Abstract:
... Dew point specifications are of high interest in the natural gas industry. The CPA equation of state (EoS) was previously validated against both water content and phase equilibrium data. Moreover, solid model parameters were estimated for four natural gas main components (methane, ethane, propane, and carbon dioxide). In this study we have extended the use of CPA EoS to perform equilibrium tempera ...

Abstract:
... The global natural gas demand is expected to rise continuously over the next decades, compelling industries to study and develop new natural gas purification processes, such as those using low-temperature, in order to allow the profitable exploitation of low-quality gas reserves (with high contents of CO₂ and/or H₂S) that up to some years ago were not considered suitable for their commercializatio ...

Abstract:
... Different strategies for the generation of Ni (15 wt %)/Al₂O₃ catalytic coatings onto cordierite monoliths applied to the oxidative dehydrogenation of ethane (ODHE) were investigated. Strategy 1 involved the deposition of an alumina layer (nanoparticles or micro + nanoparticles) and the later incorporation of the active phase. Strategy 2 employed a suspension containing a powder catalyst that was ...
