R&D & Technology Development · Process Development · Scale-Up
From molecular mechanisms to validated industrial decisions
Dr. Ahmad Saylam is an R&D and technology-development leader with more than 35 years of experience connecting applied physical chemistry, chemical kinetics, reactor and CFD modelling, experimental validation, process and pilot development, and industrial scale-up across reactive, thermochemical and sustainable process systems.
Integrated capability
Scientific depth directed toward practical technology development
The work combines fundamental understanding, fit-for-purpose modelling, experimental evidence and engineering interpretation. Each method is selected according to the decision, uncertainty, available data and required scale.
Reactive Systems & Chemical Kinetics
Oxidation, ignition, combustion, emissions, detailed mechanisms, sensitivity, reaction networks, mechanism reduction and nanoparticle inception.
Reactor, CFD & Multiscale Modelling
Zero- to three-dimensional models, reactive-flow CFD, heat and mass transfer, species transport and experiment–model comparison.
Thermochemical & Sustainable Processes
Pyrolysis, gasification, reforming, syngas, biomass, biochar, waste-to-X, chemical recycling and circular resource pathways.
Validation, Pilot Development & Scale-Up
Technical feasibility, evidence assessment, experimental design, pilot configuration, operability, process risk and industrial implementation decisions.
Selected public evidence
Reproducible resources with explicit maturity boundaries
Public work is presented according to its actual status. An engineering diagnostic, a tested screening framework, a research reconstruction and a scientific hypothesis are not treated as equivalent evidence.
Desulfurization Reaction–Transport Regimes
A structured method for distinguishing kinetic, transport, adsorption, hydrodynamic and downstream-separation limitations before selecting a process intervention.
AOP Kinetic Process Framework
Matrix-aware calculations for radical scavenging, apparent kinetics, oxidant utilization, treatment time and engineering interpretation of advanced oxidation processes.
Biochar Process Modeling
Simplified Cantera-based reactor examples, curated cases and model-consistency guidance for biomass conversion, biochar, syngas and heat-production studies.
NDMS Persistence–Stabilization Closure
A falsifiable conceptual framework for examining the transition from reversible precursor association to persistent combustion nanoparticle inception.
Development method
A controlled path from technical question to implementation
Scientific and engineering activities are linked through one development logic rather than performed as isolated tasks.
Clarify the system, objective, constraints, uncertainties and required decision.
Identify the governing chemistry, transport, thermodynamics and process interactions.
Select the simplest defensible model—from screening calculations to detailed kinetics or CFD.
Compare against measurements, balances, literature, benchmarks and predefined acceptance criteria.
Convert evidence into pilot design, scale-up, risk, operability and industrial decisions.
Methods and computational environments
Complementary tools selected according to the problem
CFD & Reactive Flow
ANSYS Fluent and OpenFOAM for combustion, species transport, heat transfer, multiphase systems and coupled flow–reaction analysis.
Chemical Kinetics
CHEMKIN and Cantera for reactor simulation, detailed mechanisms, sensitivity, reduction, validation and adaptive chemistry development.
Scientific Computing
Python, Fortran, MATLAB, C/C++ and Jupyter for modelling, reconstruction, testing and reproducible analysis.
Engineering Analysis
Thermodynamics, reaction engineering, heat and mass transfer, process calculations, diagnostics, optimization, uncertainty and scale-up assessment.
Professional engagement
Selected scientific, engineering and advisory collaboration
Relevant discussions may concern R&D leadership, specialist and technical-project roles, process and technology development, modelling, experimental validation, pilot planning, scale-up and focused engineering decision support.
Evidence and provenance policy
Public credibility requires technical and rights control
Public content is selected rather than bulk-published. Scientific value, ownership, confidentiality, licensing, validation and suitability for professional communication are reviewed before release.
Evidence status
Hypotheses, screening tools, reconstructed models, experimental observations and validated results are labelled according to their actual maturity.
Authorship and rights
Historical programs, mechanisms, figures, manuscripts and data are reviewed for authorship, ownership, licences and third-party restrictions.
Confidentiality
Client, employer and project information is excluded unless it is public, non-confidential, rights-cleared and appropriate for professional reuse.
Contact
Professional discussion and technical collaboration
Relevant discussions may concern R&D leadership, scientific engineering, modelling, validation, technology development, scale-up or international technical collaboration.
Professional profiles
Confidential or proprietary information should not be sent before an appropriate confidentiality arrangement is in place.
