“…A large effort was undertaken by Grace to improve MAT protocol at the end of 90's, resulting in SCT-MAT (Short Contact Time-MAT). Catalyst bed was diluted and an insert was used to minimize temperature drop and temperature profiles [13,14]. Reactor internals were modified to minimize dead volumes.…”

As the FCC process has evolved over decades, several laboratory scale equipment have appeared to maintain a proper assessment of catalysts activity. Several laboratory equipments are available for simulating the FCC process, from the well known fixed bed, MicroActivity Test to newer, fluid bed or transported bed units. As well, a number of units have been created to simulate other parts of the process such as regenerator or stripper, The increased pressure for treating non-conventional feeds, from reprocessing gasoline to extra-heavy feeds or oils produced from biomass containing large amounts of heteroatoms, increase the needs to have a laboratory test which is as close as possible to the process so that data extraction from the laboratory test are simplified, thus less prone to errors or misunderstanding. KeywordsLaboratory testing, catalytic cracking, naphtha cracking, coked catalyst, biooil cracking Highlights• FCC process is adapting to new feeds and new processes• Heavy resid feeds and biomass-derived feeds are being extensively tested • Significant operation and process changes are contemplated to squeeze maximum value from feeds: naphtha reprocessing, use of partially coked catalysts, several independent risers. 3

“…Both fixed and fluid bed equipments have been shown to provoke ranking reversal compared with pilot plant results [2,13,22]. This has prompted the development of reactors that better mimic the catalyst and feed contact in the FCCU riser.…”

“…The work was accomplished by investigating the impact of matrix modification of the FCC catalyst series with the different rare earth contents on catalytic performance. Cracking experiments were performed in a microactivity test unit at short catalyst time-on-stream; the accuracy of this test had been validated by comparisons with data generated in riser pilot units [17]. The catalysts with the high metal loading were tested with a resid feed whilst for the testing of the moderately loaded and metals-free catalysts a heavy vacuum gas-oil was employed.…”
