the reactor, for example, substituting the inert material layer at the inlet of the reactor with a very low-activity catalyst. Finally, an extra layer of complexity that this type of feed- stock raises is the analysis of the products by SIMDIST or GC. The final hydroprocessed products, if not fractionated, will very often still contain macromolecules that are not eluted by the GCs and potentially clog the columns. Therefore, the usual ASTM standards are not perfectly applicable to these feedstocks, highlighting how much research and prepara- tory work is still needed to bring this type of feedstock to a viable technology readiness. 1 Outlook/conclusions The versatility of high throughput technology will be crucial in transitioning from fossil to renewable feedstocks. High throughput testing allows the retrieval of a lot of data for one or more catalysts in a timeframe of weeks instead of months, decreasing the effort necessary to develop, for example, a complete kinetic dataset. The high density of information obtained by only one run is key for decision-making, for example, in catalyst benchmarking or screening. It is a tool that every refinery or R&D institution can rely on to get quick information on the performance of their sys- tems. Additionally, this overview highlighted all the chal- lenges associated with the implementation of renewable feedstocks on a small scale; things only get more complex on a larger scale. Therefore, it is very important for refiner - ies to test the catalysts before implementing them in their commercial unit with new types of feedstocks.
