“…There is still potential improvement in acrolein selectivity. In further we intend to use the total manufacturing cost as the observation target to investigate the influence of the acrolein selectivity (92-98 %) in the GTA process, as well as investigating the acrolein selectivity (82-92 %) from the literature [18,25,29,42,46], including our previous work [30]. There was obviously a linear relationship between acrolein selectivity and total manufacturing cost (see Fig.…”

The production of acrolein by the dehydration of glycerin (GTA) was compared with formaldehyde/acetaldehyde aldolization (FAA) and propylene oxidation (PO) by using the Aspen Plus 11.1 process design software. The fixed assets cost of the FAA, PO, and GTA process were estimated as 61.95, 41.73, and 39.09 million CNY, respectively, for a 40-kt a -1 plant, and the total manufacturing costs were estimated as 10637, 8873, and 8974 CNY t -1 , respectively. The PO process is the most economical under current market and technology conditions. Nevertheless, the renewable process outshone traditional processes if the propylene price was greater than or equal to 8200 CNY t -1 at a glycerin price of 3800 CNY t -1 , as long as the yield of acrolein from GTA was greater than or equal to 93 %.

Combinatorial screening of 150 supported metal oxide (manganese and additives) catalysts was carried out via a high-throughput synthesis platform and parallel reactors for the oxidative dehydrogenation (ODH) of propane to propylene. Specifically, an organomanganese (0.05−2.5 Mn atoms/nm 2 ) complex was grafted on metal oxide supports (Al 2 O 3 , SiO 2 , TiO 2 , and ZrO 2 ) premodified with either Lewis acid (Al, Ti, Zn, and Zr) or redox-active (Cu, Cr, Ga Ni, V) additives at various surface coverages (25, 50, and 75%). Catalysts were characterized by high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman spectroscopy, and UV−vis spectroscopy. Catalysts 0.05 Mn/V(50%)/Al 2 O 3 and 0.05 Mn/Ni(50%)/ZrO 2 showed the highest combined propane conversion and propylene selectivities (31/41% and 15/85%), with excellent stability at 500 °C for 25 h. The presence of Ni in Mn/Ni/ZrO 2 resulted in a 6-fold increase in turnover frequency (TOF) over the Mn/ZrO 2 . HRTEM identified single Mn atoms after 500 °C heat treatment. For the Mn/Ni/ZrO 2 system, Mn was incorporated into the support lattice due to the similar ionic radius of Mn 2+ and Zr 4+ , which was also enhanced by the presence of Ni. For the Mn/V/Al 2 O 3 system, highly active MnO was prevalent as observed by Raman. Both V and Mn contributed to an increase in mutual dispersion, but both species remained on the surface. It is proposed that the highly dispersed atom and interactions between Mn with either Ni or V are responsible for the ODH performance and stability.
