The present work deals with hydrogen generation from JP8 reformation and clean-up of the reformate to produce PEMFC quality hydrogen. The fuel processor has reformer, postformer, water gas shift reactors, H2S removal, preferential CO oxidation, and CO2 removal stages. The processor also incorporates a final adsorbent fuel filter that can efficiently remove ppm level impurities that may poison t...

This review study summarized the Supercritical Fluid Extraction (SFE) as new analytical method. The advantage and disadvantage of CO2 (SC-CO2 )as well as special applications of SFE in food processing such as removal of fat from food, enrichment of vitamin E from natural sources, removal of alcohol from wine and beer, encapsulation of liquids for engineering solid products and extraction and ch...

The Extracorporeal CO2 removal device (ECCO2RD) is used in clinics to treat patients suffering from respiratory failures like acute respiratory distress syndrome (ARDS) or chronic obstructive pulmonary disease (COPD). The aim of this device is to decarboxylate blood externally with low blood flow. A mathematical model is proposed to describe protective ventilation, ARDS and an extracorporeal CO...

Changes in climate and atmospheric CO2 and nitrogen (N) over the last several decades have induced significant effects on forest carbon (C) cycling. However, contributions of individual factors are largely unknown because of the lack of long observational data and the undifferentiating between intrinsic factors and external forces in current ecosystem models. Using over four decades (1956-2001)...

Covalent organic framework (COF) membranes used for selective removal of CO2 were believed as an efficient and low-cost solution to energy and environmental sustainability. In this study, the amide modified COF nanosheet cluster with a 2D structure was facilely prepared through solid reaction, exhibiting good adsorption-based CO2 selectivity (223 at 273 K and 90 at 298 K) toward N2. Remarkably,...

Carbon dioxide (written as CO2) releases from fossil fuels cause climate change, a warming of the earth that causes more intense heat waves, extreme weather, and other negative impacts on our world. How can we stop future climate change? One option is to remove CO2 from the air around us. Here, we describe an original carbon dioxide removal technology called bioenergy with carbon capture and se...

Agricultural residues are the largest near term source of cellulosic biomass for bioenergy production, but removing agricultural residues sustainably requires considering the critical roles that residues play in the agronomic system. Determination of sustainable removal rates for agricultural residues has received significant attention and integrated modeling strategies have been built to evalu...

Defatted bovine liver (DBL) is a potential source of protein and minerals. Supercritical carbon dioxide (SC-CO2) and a traditional organic solvent method were used to remove lipid from bovine liver, and the quality characteristics of a control bovine liver (CBL), bovine liver defatted by SC-CO2 (DBLSC-CO2) at different pressures, and bovine liver defatted by organic solvent (DBL-OS) were compar...

The introduction and removal of protecting groups is ubiquitous in multi-step synthetic schemes. From a green chemistry standpoint, however, alternative strategies that employ in situ and reversible protection and deprotection sequences would be attractive. The reversible reactions of CO2 with amines could provide a possible vehicle for realizing this strategy. Herein, we present (1) the produc...

OVERVIEW: Among the international efforts to curb global warming, practical application of CO2 removal technology and improvement of powergeneration efficiency — for reducing CO2 emission from thermal power plants (which will probably remain the prime source of power in future) — will, at the very least, become urgent issues over the next several decades. Accordingly, the Hitachi Group is aimin...
