Warying thee feed flow rate (and thus the residence time) is a primary lever. Short residence times lead to high throut but lower conversion; long residence times increate conversion but may lead to over- reaction or catalist deactivation.

Experimental Design andData Analysis

Design of Experiments (DoE)

HTS designs included full factorial (for ≤ 4 variables), fractional factorial (to screen many variables), Plackett- Burman (for identifying main effects), and central composite or Box- Behnken (for second-order response surface).

Metodologia powierzchni Response Surface (RSM)

After screening, a smaller number of variables (2- 4) are studied in detail using RSM. A quadratic regression model is fitted the metriured responses (e.g., conversion, yield, selectivity). The fitted surface can be contoured to locate a stationary optimum (maximum or minimum). The model also quantifies the curvatare and interaction effects. 1; FLT: 0 metribull 3x3; Validation runs; 1; FLT: 1; FLT: 3t; AE; At; At; At; At; At; At; At; At; At; Pprovimum procum conformt.

Integration wigh Kinetic Modeling

HTS data are often combined with first-principles kinetic models. For example, a proposed reaction mechanism with rate constants can be fitted to concentration vs. time profiles from multiple HTS experiments (varying T, pH, feed). This provideces a robust model that can predict performance under untested conditions, enabling in- silico optionation.
