The pilot-scale system has a nominal maximum H2 production rate of 45 kg/day. It comprises of a downdraft gasifier; a reactive and adsorption system (RAS), consisting of a water gas shift (WGS) reactor and a multistage adsorption-based purification system for impurity removal, and a pressure swing adsorption (PSA) unit to produce high-purity H2. The DT model, implemented in MATLAB and DO-MORE software, serves as a virtual replica of the physical plant. Its use allowed the design and construction of the pilot-scale system based solely on lab-scale-generated catalytic reaction kinetics and adsorption-based purification studies. Model validation was conducted in Phase I of the project employing synthetic syngas mixtures representative of oxygen/steam-blown gasification conditions at a feed flow rate of 10 SCFM and a H2 production rate of ∼21 kg/day. The DT demonstrated good accuracy in predicting system temperatures (RMSE = 13.82 °C, MAE = 11.3 °C, MAPE = 2.9%) and gas compositions and conversion (RMSE = 1.7%, MAE = 1.71%, MAPE = 2.1%), confirming its reliable representation of reaction kinetics and mass and energy balances. The DT incorporates methodologies that allow for real-time process monitoring, enabling the real-time optimization of heating and liquid flows within the pilot plant, resulting in better thermal management and reduction in utility costs across the RAS system. In Phase II of the project, we will extend this control architecture through the integration of steam and gas flow controllers, thus achieving complete closed-loop control of the system. The system will be operated with real syngas from the gasifier at its maximum operating capacity of 25 SCFM, corresponding to a H2 production output of 45 kg/day. Techno-economic analysis estimates the levelized cost of hydrogen (LCOH), over a 20 year plant life, operating at such capacity, and a 7% discount rate to be $2.33/kg. These results establish a scalable and economically viable pathway for waste-to-hydrogen production and future commercialization, validating the impact of a DT to enhance process economics at scale.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"26 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149210005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has been achieved by tracking the evolution of deterministically arranged dyad (DAD) concentrations as reactions consume and produce functional groups stoichiometrically. Additionally, reaction site probabilities are calculated using the ratios of concentrations of different DAD types, allowing reaction rates to be a function of the average structure in addition to temperature and species concentration. Two models were constructed, one for the pyrolysis of a homopolymer, poly(vinyl alcohol) (PVA), and another for the pyrolysis of a related copolymer, ethylene vinyl alcohol (EVOH), to demonstrate the robustness of this approach. This work demonstrates both the wide applicability of this methodology as well as the importance of including the influence of evolving polymer structure on the competing degradation chemistries that govern the depolymerization of these systems. This first installment focuses on uncovering the specific mechanistic pathways by which PVA and EVOH decompose under pyrolytic conditions, the generalized method for initializing and tracking the evolution of DADs, and the calculation of the expected concentrations of the reaction sites.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"11 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149152093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observe that the temporal evolution of elastic moduli shifts to lower aging times at higher concentrations of the salt. The static yield stress evolves with time and is observed to increase with increasing salt concentrations. We find that the system displays hyperaging dynamics, wherein the relaxation time grows faster than linearly with the time elapsed since shear cessation. Interestingly, after flow cessation, the system initially exhibits a stress decay, but this is followed by a stress buildup after reaching a minimum. We used a simple time-dependent linear Maxwell model framework that qualitatively predicts the experimentally measured stress response. We attribute the observed stress buildup response to a combination of hyperaging dynamics and time-dependent evolution of the elastic modulus. The mechanism underlying this stress relaxation and subsequent buildup behavior is obtained by showing a correlation between the logarithmic rate of stress buildup and the logarithmic rate of microstructural aging that is observed to be of the same order of magnitude over the range of explored salt concentrations.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"64 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149210048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we revisit the Fokker–Planck based theory of driven polymer translocation through a narrow nanopore. A bead–spring model of a uniformly charged polyelectrolyte chain translocating through a semi-implicit model of a nanopore embedded in a membrane are used to gain insights into the underlying free energy landscape and kinetics of translocation. The free energy landscape is predicted using metadynamics simulation, an enhanced sampling method. A direct comparison with the theoretical free energy formulation proposed in the literature allows us to introduce a modification related to the entropic contribution in the theory. Additional classical Langevin dynamics simulation runs are performed to obtain the translocation time distribution for polymers of lengths N driven by voltages V through nanopores of radii rp. In agreement with earlier reports, a scaling of the mean translocation time ⟨τLD⟩ ∼ Nα/V is observed, with α ∼ 1.40–1.48 depending on the nanopore size. Fitting the mean exit time ⟨τFP⟩ given by the Fokker–Planck theory to Langevin dynamics simulation results helps gain insights into the diffusivity kFP used in the theory. We report a peculiar variation of kFP with N in the range of N and rp studied, which significantly deviates from the Rouse prediction of kFP ∼ N–1 for the center-of-mass diffusivity of a polymer chain. Predictions from the modified theory agree with several experimentally observed scaling results in the literature. The theoretical framework can be utilized in developing nanopore technology for molecular characterization and selective separation of polymers.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"53 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149152062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
