Reduction of carbon dioxide emission through the sorption in situ using a fluidised bed reactor

Energy Policies for Carbon Dioxide Emission Reduction

Improvement of Methanol Synthesis Process through a Novel Sorption-Enhanced Fluidized-bed Reactor, Part I: Mathematical Modeling

In the first part of two section paper, a mathematical model of the fluidized bed reactor in the presence of in-situ water adsorbent for methanol synthesis is assessed. The bubbling two-phase regime is applied to model the fluidization concept. The binary adsorbent and catalyst particles system can be separated from each other based on their density difference. The heavy catalyst particles tend...

the effect of consciousness raising (c-r) on the reduction of translational errors: a case study

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...

Compact and Lightweight Sabatier Reactor for Carbon Dioxide Reduction

The utilization of CO2 to produce life support consumables, such as O2 and H2O, via the Sabatier reaction is an important aspect of NASA’s cabin Atmosphere Revitalization System and In-Situ Resource Utilization architectures for both low-earth orbit and long-term manned space missions. In the current International Space Station (ISS) and other low orbit missions, metabolically-generated CO2 is ...

Carbon Dioxide Gasification of Kraft Black Liquor Char in a Laboratory Char Bed Reactor

In the current study a series of pyrolysis and CO2 gasification experiments were conducted on a bed of kraft black char under a perpendicular impinging jet. The experiments demonstrated that the char bed carbon gasification rates are externally mass transfer limited. The mass transfer is further decreased by a net molar out-flow caused by the conversion of one mole of reactant CO2 to two moles ...
