equilibrium methanol concentration C eq (CH 3 OH) = 22 vol.% ( Fig. 3 ). Methane, ethane, propane and dimethyl ether (DME) were detected as well in negligible amounts ( C out (CH 4 ) = 0.08–0.11 vol.%, C out (C 2 H 6 ) = 0.01–0.03 vol.%, C out (C 3 H 8
and CT is the catalytic test under oxygen lean conditions of propene (C 3 H 6 : air 1:10 mixture). The total flow rate was 72 mL/min. Before each heating run (between room temperature and 400 °C with a ramp of 2 °C/min), the sample was
Syntheses Lanthanide citrates [LnL· x H 2 O] and [Ln 2 (LH) 3 ·2H 2 O], L = (C 6 H 5 O 7 ) 3− and LH = (C 6 H 6 O 7 ) 2− were synthesized following procedures already published [ 32 ]. These salts were named, respectively, precursor type 1 and 2

-temperature decomposition of AP-based solid propellant can be expressed as a sum of the AP decomposition activation energy ( E aAP ) and a half of the AP dissociative sublimation heat (Δ H ): 6 Some aspects of high-temperature decomposition of so-called volatile EM
material has been previously synthesized using the solid state reaction, with a temperature treatment above 1000 °C/24 h [ 6 ]. In this work, Fe 3+ doped strontium stannate (SrSnO 3 ) was synthesized by the polymeric precursor method. The polymeric
