1A techno-economic and life cycle assessment for the production of green methanol from CO_(2): catalyst and process bottlenecks显示文摘The success of catalytic schemes for the large-scale valorization of CO_(2) does not only depend on the development of active,selective and stable catalytic materials but also on the overall process design.Here we present a multidisciplinary study(from catalyst to plant and techno-economic/lifecycle analysis)for the production of green methanol from renewable H2 and CO_(2).We combine an in-depth kinetic analysis of one of the most promising recently reported methanol-synthesis catalysts(InCo)with a thorough process simulation and techno-economic assessment.We then perform a life cycle assessment of the simulated process to gauge the real environmental impact of green methanol production from CO_(2).Our results indicate that up to 1.75 ton of CO_(2) can be abated per ton of produced methanol only if renewable energy is used to run the process,while the sensitivity analysis suggest that either rock-bottom H2 prices(1.5$kg1)or severe CO_(2) taxation(300$per ton)are needed for a profitable methanol plant.Besides,we herein highlight and analyze some critical bottlenecks of the process.Especial attention has been paid to the contribution of H2 to the overall plant costs,CH4 trace formation,and purity and costs of raw gases.In addition to providing important information for policy makers and industrialists,directions for catalyst(and therefore process)improvements are outlined.Tomas Cordero-Lanzac Adrian Ramirez Alberto Navajas Lieven Gevers Sirio Brunialti Luis MGandía Andrés T.Aguayo S.Mani Sarathy Jorge Gascon 2022Journal of Energy Chemistry2022,31,5:3
2Capsule endoscopy capture rate: Has 4 frames-per-second any impact over 2frames-per-second?显示文摘AIM: To compare the current capsule and a new prototype at 2 and 4 frames-per-second, respectively, in terms of clinical and therapeutic impact. METHODS: One hundred patients with an indication for capsule endoscopy were included in the study. All procedures were performed with the new device(SB24). After an exhaustive evaluation of the SB24 videos, they were then converted to 'SB2-like' videos for their evaluation. Findings, frames per finding, and clinical and therapeutic impact derived from video visualization were analyzed. Kappa index for interobserver agreement and χ2 and Student's t tests for qualitative/quantitative variables, respectively, were used. Values of P under 0.05 were considered statistically significant.RESULTS: Eighty-nine out of 100 cases included in the study were ultimately included in the analysis. The SB24 videos detected the anatomical landmarks(Zline and duodenal papilla) and lesions in more patients than the 'SB2-like' videos. On the other hand, the SB24 videos detected more frames per landmark/lesion than the 'SB2-like' videos. However, these differences were not statistically significant(P > 0.05). Both clinical and therapeutic impacts were similar between SB24 and 'SB2-like' videos(K = 0.954). The time spent by readers was significantly higher for SB24 videos visualization(P < 0.05) than for 'SB2-like' videos when all images captured by the capsule were considered. However, these differences become non-significant if we only take into account small bowel images(P > 0.05).CONCLUSION: More frames-per-second detect more landmarks, lesions, and frames per landmark/lesion, but is time consuming and has a very low impact on clinical and therapeutic management.Ignacio Fernandez-Urien Cristina Carretero Erika Borobio Ana Borda Emilio Estevez Sara Galter Begoa Gonzalez-Suarez Benito Gonzalez Marisol Lujan Jose Luis Martinez Vanessa Martínez Pedro Menchén Javier Navajas Vicente Pons Cesar Prieto Julio Valle 2014World Journal of Gastroenterology2014,20,39:2
