The Fischer–Tropsch to olefins（FTO） process is a method for the direct conversion of synthesis gas to lower C–Colefins. Carbon-supported iron carbide nanoparticles are attractive catalysts for this *** catalytic activity can be improved and undesired formation of alkanes can be suppressed by the addition of sodium and sulfur as promoters but the influence of their content and ratio remains poorly understood and the promoted catalysts often suffer from rapid deactivation due to particle growth. A series of carbon black-supported iron catalysts with similar iron content and nominal sodium/sulfur loadings of 1–30/0.5–5 wt% with respect to iron are prepared and characterized under FTO conditions at 1and 10 bar syngas pressure to illuminate the influence of the promoter level on the catalytic *** particles and promoters undergo significant reorganization during FTO operation under industrially relevant conditions. Low sodium content（1–3 wt%） leads to a delay in iron carbide formation. Sodium contents of 15–30 wt% lead to rapid loss of catalytic activity due to the covering of the iron surface with promoters during particle growth under FTO operation. Higher activity and slower loss of activity are observed at low promoter contents（1–3 wt% sodium and 0.5–1 wt% sulfur） but a minimum amount of alkali is required to effectively suppress methane and C–Cparaffin formation. A reference catalyst support（carbide-derived carbon aerogel） shows that the optimum promoter level depends on iron particle size and support pore structure.

The deactivation behavior by crystallite growth of nickel nanoparticles on various supports（carbon nanofibers, zirconia, Si C, α-Al2O3 and γ-Al2O3） was investigated in the aqueous phase reforming of ethylene glycol. Supported Ni catalysts of ~10 wt% were prepared by impregnation of carbon nanofibers（CNF）,Zr O2, SiC, γ-Al2O3 and α-Al2O3. The extent of the Ni nanoparticle growth on various support materials follows the order CNF ~ ZrO2〉 SiC 〉 γ-Al2O3〉〉 α-Al2O3 which sequence, however, was determined by the initial Ni particle size. Based on the observed nickel leaching and the specific growth characteristics; the particle size distribution and the effect of loading on the growth rate, Ostwald ripening is suggested to be the main mechanism contributing to nickel particle growth. Remarkably, initially smaller Ni particles（~12 nm） supported on α-Al2O3 were found to outgrow Ni particles with initially larger size（~20 nm）. It is put forward that the higher susceptibility with respect to oxidation of the smaller Ni nanoparticles and differences in initial particle size distribution are responsible for this behavior.

Background: Liver regeneration is crucial to restore the functional liver mass after liver resection. The aim of this study was to evaluate the early postoperative changes in remnant liver function, volume and liver stiffness after major liver resection and their correlation with postoperative outcomes. Methods: patients undergoing major liver resection (≥3 segments) between February and November 2018 underwent both functional assessment using technetium-99m mebrofenin hepatobiliary scintigraphy (HBS) and CT-volumetry of the (future) remnant liver on preoperative day 1, the 5th postoperative day, and 4-6 weeks after resection. At the same time points, patients underwent transient elastography (TE) for the assessment of liver stiffness. Severe postoperative complications (Clavien-Dindo ≥ 3A) and mortality were correlated with the functional and volumetric increases of the remnant liver. Liver failure was graded according to the International Study Group of Liver Surgery (ISGLS) criteria. Results: A total of 18 patients were included of whom 10 (56%) had severe complications and one patient (5%) developed liver failure. Function and volume of the remnant liver had increased by the 5th postoperative day from 6.9 (5.4-10.9) to 9.6 (6.7-13.8) %/min/m2, p=0.004 and from 795.5 (538.3-1,037.5) to 1,080.0 (854.0-1,283.3) mL, ppectively. After 4-6 weeks, remnant liver volume had further increased [from 1,080.0 (854.0-1,283.3) to 1,222.0 (1,016.0-1,380.5) mL, p=0.035], however, liver function did not show any significant, further increase [from 9.6 (6.7-13.8) to 10.9 (8.8-13.6) %/min/m2, p=0.177]. Liver elasticity of the future remnant liver (FRL) increased [from 10.8 (5.7-18.7) to 17.5 (12.4-22.6) kpa, p=0.018] and gradually recovered after 4-6 weeks to a median of 10.9 (5.7-18.8) kpa (T3 vs. T4, p=0.079). patients who had severe postoperative complications did not show a significant increase in liver function on the 5th postoperative day (p=0.203), despite increas
