Abstract:
Hythane, the blending of hydrogen (H2) and methane (CH4), is attracting attention as it could accelerate the H2 economy. H2 and CH4 can be extracted from organic material by fermentation and anaerobic digestion, respectively, but this alternative bio-hythane also contains carbon dioxide (CO2) that must be removed. This work addresses the use of Aprotic N‑Heterocyclic Anion-based ionic liquids (AHA-ILs) for bio-hythane upgrading. Three AHA-ILs ([P2228][2-CNPyr], [P2228][3-IPyra], and [P2228][4-BrIm]) were evaluated at process scale by conducting rate-based COSMO-based/Aspen Plus simulation

Abstract:
The separation via the extractive distillation of 1,3-butadiene from C4 hydrocarbon mixtures is an essential step in synthetic rubber and plastic production. Conventional extractive distillation methods rely on solvents such as N,N-dimethylformamide (DMF) and N-methyl-2-pyrrolidone (NMP), which, despite their efficiency, pose significant environmental and health risks. This study investigates the feasibility of replacing these hazardous solvents with 1,2-propylene carbonate (PC), a greener alternative that aligns with REACH restrictions and CEFIC recommendations.

Abstract Background Moderate to severe ulcerative colitis (UC) exerts a significant burden on patients’ lives. Patients with UC report that bowel urgency has a substantial negative impact on their quality of life and psychosocial functioning, however, this symptom is missing from most disease activity indices. Purpose The Communicating Needs and Features of IBD Experiences (CONFIDE) study aims to increase understanding of the impact of symptoms, including bowel urgency, on the lives of patients (pts) with moderate to severe UC and Crohn’s disease in the United States (US), Europe (EUR), and Ja

Abstract Background Ulcerative colitis (UC) can result in a high prevalence of bowel movement urgency (BU), significantly reducing patient quality of life. Purpose Early BU improvement association with later clinical endpoint improvements was examined in moderately-to-severely active UC patients (pts) treated with mirikizumab (miri). Method BU was evaluated in Phase 3 randomized placebo (PBO)-controlled 12-week induction (LUCENT-1, NCT03518086) and 40-week maintenance (LUCENT-2, NCT03524092) trials with miri.

Abstract:
AbstractThe actual applications of extraction methods for α‐olefins separation are limited by their long time and high energy consumption. Hence, this study employs microwave technology to intensify the extraction process using Ag‐based ionic liquid (Ag‐IL), where the influence of microwave irradiation and the mechanism of microwave‐assisted ionic liquid extraction (MAILE) are investigated, along with a comprehensive techno‐economic analysis of process feasibility. The results of COSMO‐RS and DFT simulations demonstrate the dominant role of π‐complexation in identifying Ag‐IL with high selecti
