“…Calcite and hydrotalcite are examples of inorganic materials, which can be prepared using CO 2 whereby the CO 2 is not, or only partially, fixed (Yong et al, 2002). Physical utilization is highly promising as CO 2 can be involved in a wide range of applications, it can, e.g., be used as refrigerant for fire extinguishers or cleaning processes (Markewitz et al, 2012) and for the carbonation of beverages (Duran et al, 2008). In comparison diverse types of chemical utilization revealed to be most efficient (Fan et al, 2015) as there are diverse options which allow the long-term, partially permanent, storage of CO 2 , e.g., by producing urea, methanol (e.g., production of fuels), cyclic carbonates, and salicylic acid (e.g., Markewitz et al, 2012).…”

Climate change poses a key threat to today's societies and is caused by greenhouse gas emissions, mainly carbon dioxide emissions. Capture and Utilization of Carbon Dioxide (CCU) is a technological approach to reduce CO 2 emissions. Coincidentally, the approach also reduces the depletion of limited fossil resources by incorporating CO 2 as a raw material in the manufacture of products (e.g., plastics), thereby replacing fossil resources such as conventionally used oil. Even though some CCU products are nearing market maturity, systematic research on the acceptance of these products, especially regarding the (dis)trust in the companies that produce them, is still in its initial phase. Since a lack of trust could lead to a rejection of innovative products and technologies, the present study empirically investigates (dis)trust factors related to the acceptance of CCU plastic products. In a first step, interviews were carried out and analyzed to reveal relevant (dis)trust criteria for credibility of companies, desired information and marketing issues, and how CCU products are perceived. Afterwards, an online survey (n = 127) was conducted to identify and quantify important (dis)trust dimensions, and their connection to the acceptance of CCU products. The results showed that the participants had a slightly positive attitude toward CCU, and potential environmental, sustainability related, and economic benefits were acknowledged. In addition, potential barriers of CCU (sustainability risks, unknown risks, and health concerns) were rated rather neutrally and were thus not perceived as real barriers of CCU. When comparing companies to other institutions (e.g., research institutions, NGOs), the participants reported to trust companies least. Furthermore, four relevant trust (e.g., customer relationship) and distrust (e.g., bad customer orientation) dimensions were identified using CCU companies as an example of companies which manufacture innovative products. Finally, some first insights concerning the connection between the identified trust factors, CCU perception, credibility of the information sources, and the marketing of innovative products, are presented. The results enable deriving user-specific CCU product communication and information strategies.

Innovative technological approaches aim to reduce Carbon Dioxide (CO 2) emissions by emitting no, or considerably less, CO 2 and by replacing the use of fossil resources (Adger et al., 2013), e.g., through energy generated by renewable resources (Twidell and Weir, 2015) or advancements in the field of electromobility (Held and Baumann, 2011). Despite these efforts, considerable amounts of CO 2 emissions are currently still being ejected-particularly by power plants. Carbon Dioxide Capture and Utilization (CCU) is an option for the capture of CO 2 emissions from power plants, after which these are used as carbon feedstock for the manufacture ...

“…Because COS, H 2 S, and benzene are possible impurities, special automatic sensor systems, custom-made for the beverage industry, have been developed to detect them. [305] Likewise, strict purity criteria apply to many of the extraction processes discussed below. Consequently, CO 2 from fermentation is favored over other CO 2 sources.…”

Chemical Technologies for Exploiting and Recycling Carbon Dioxideinto the Value Chain

While experts in various fields discuss the potential of carbon capture and storage (CCS) technologies, the utilization of carbon dioxide as chemical feedstock is also attracting renewed and rapidly growing interest. These approaches do not compete; rather, they are complementary: CCS aims to capture and store huge quantities of carbon dioxide, while the chemical exploitation of carbon dioxide aims to generate value and develop better and more-efficient processes from a limited part of the waste stream. Provided that the overall carbon footprint for the carbon dioxide-based process chain is competitive with conventional chemical production and that the reaction with the carbon dioxide molecule is enabled by the use of appropriate catalysts, carbon dioxide can be a promising carbon source with practically unlimited availability for a range of industrially relevant products. In addition, it can be used as a versatile processing fluid based on its remarkable physicochemical properties.

A Micropreconcentrator Design Using Low Temperature Cofired Ceramics Technology for Acetone Detection Applications

We design and manufacture the gas micropreconcentrator in low temperature cofired ceramics (LTCC) technology. The structure is 1.2-mm thick and has lateral dimensions of 25 × 20 mm. It consists of eight layers of LTCC green tapes with spiral-shaped channel filled with absorbing powder. Two heaters covered by the ceramic foils are embedded over and below the channel. The heaters are required for heating the adsorbent to elevated temperatures during its activation and desorption processes. In this paper, we describe the fabrication processes of a micropreconcentrator structure designed for acetone detection applications together with thermal and preconcentration measurements of the device. Commercially available adsorbents: Carboxen-1018, Carboxen-1012, and Carboxen-1003 from Sigma-Aldrich are selected and tested in order to concentrate low levels of acetone. The best concentration factor obtained is 5250.
