High Carbon Dioxide

Green bananas were held in humidified gas streams comprising air (control); "high carbon dioxide" (A) (5% CO2, 20% O2,75% N2); "low oxygen" (B) (0% CO2, 3%,02,97% N2); "high carbon dioxide-low oxygen" (C) (5% CO2, 3% O2, 92% N2). Ripening in A, B, and C was delayed at least 2, 8, and 12 times respectively compared with air. These three gas streams also reduced the rates of oxygen uptake by the fruit but increased the total oxygen uptake over the period before the beginning of the respiratory climacteric.

High Carbon Dioxide

Species within subfamilies and tribes of the Gramineae that have low carbon dioxide compensation values are either short-day or day-neutral in their photoperiodic requirement for flowering; those with high carbon dioxide compensation values are long-day, with a few exceptions. Photoperiodic screening of some species of Atriplex, Amaranthus, and Panicum revealed that the species with the C4 syndrome are quantitative short-day or day-neutral, except for P. miliaceum. Those lacking the C4 syndrome have a qualitative short-day requirement for flowering. It is assumed that the C4 syndrome is a derived condition from C3 plants with CAM (crassulacean acid metabolism) plants probably in between. The photoperiodic responses of the plants seem to have a coevolutionary trend with photosynthetic characters, from long-day types to short-day ones, with plants having a dual photoperiodic requirement in between.

Hydrogen is an increasingly important chemical raw material and a probable future primary energy carrier. In many current and anticipated applications the carbon monoxide impurity level must be reduced to low-ppmv levels to avoid poisoning catalysts in downstream processes. Methanation is currently used to remove carbon monoxide in petroleum refining operations while preferential oxidation (PROX) is being developed for carbon monoxide control in fuel cells. Both approaches add an additional step to the multi-step hydrogen production process, and both inevitably result in hydrogen loss. The sorption enhanced process for hydrogen production, in which steam-methane reforming, water-gas shift, and carbon dioxide removal reactions occur simultaneously in the presence of a nickel-based reforming catalyst and a calcium-based carbon dioxide sorbent, is capable of producing high purity hydrogen containing minimal carbon monoxide in a single processing step. The process also has the potential for producing pure CO2 that is suitable for subsequent use or sequestration during the sorbent regeneration step. The current research on sorption-enhanced production of low-carbon monoxide hydrogen is an extension of previous research in this laboratory that proved the feasibility of producing 95+% hydrogen (dry basis), but without concern for the carbon monoxide concentration. This paper describes sorption-enhanced reaction conditions – temperature, feed gas composition, and volumetric feed rate – required to produce 95+% hydrogen containing low carbon monoxide concentrations suitable for direct use in, for example, a proton exchange membrane fuel cell.
