Base Mix

Mix the potassium nitrate and barium nitrate with the stoichiometric amounts of the sulfur and charcoal. Add the aluminum and dextrin. This becomes the base fire. 

The stoichiometric amounts for the potassium nitrate may be calculated from the equations. The formulas are easily calculated as a weight formula. For Equation Two we had formula  

This snowball formula has 38% potassium nitrate. To calculate the percentage of charcoal and sulfur required for this percentage  

Since we had only 10% sulfur to begin with, we must use some of the sulfur equivalence in the antimony sulfide. One mole of Sb2S3 contains 243.5 grams antimony and 96.192 grams sulfur. (The formula weight of Sb2S3 is 339.692). 39.692/96.192 = 3.53, so each percent sulfur that we need will require 3.53% Sb2S3 to replace it. We need 1.9% sulfur, so we can substitute approximately 6,7% of antimony sulfide. This leaves only 2.3% antimony to go. 

This formula can be improved Remember that the disulfides are not absolutely necessary for the full equivalence of the metal ions, but delay is increased if they are equivalent. Bob Cardwell gave me an improved formula which Mike Beyer, a PGI man of years gone by, laboriously worked out by empirical trial and error.

Although catalytic wet oxidation of acetic acid, phenol, and p-coumaric acid has been reported for Co-Bi composites and CoOx-based mixed metal oxides [3-5], we could find no studies of the wet oxidation of CHCs over supported CoO catalysts. Therefore, this study was conducted to see if such catalysts are available for wet oxidation of trichloroethylene (TCE) as a model CHC in a continuous flow fixal-bed reactor that requires no subsequent separation process. The supported CoOx catalysts were characterized to explain unsteady-state behavior in activity for a certain hour on stream.

Pyruvic acid is the simplest homologue of the a-keto acid, whose established procedures for synthesis are the dehydrative decarboxylation of tartaric acid and the hydrolysis of acetyl cyanide. On the other hand, vapor-phase contact oxidation of alkyl lactates to corresponding alkyl pyruvates using V2C - and MoOa-baseds mixed oxide catalysts has also been known [1-4]. Recently we found that pyruvic acid is obtained directly from a vapor-phase oxidative-dehydrogenation of lactic acid over iron phosphate catalysts with a P/Fe atomic ratio of 1.2 at a temperature around 230°C [5]. 

Over the V2O5- and Mo03-based mixed oxide catalysts, the main part of lactic acid is converted to form acetaldehyde and CO2. 

An iron phosphate catalyst with a P/Fe atomic ratio of 1.2 used in this study was prepared according to the procedures described in the previous studies [6-8]. On the other hand, a V-P oxide catalyst with a P/V atomic ratio of 1.06 and pumice supported 12-molybdophosphoric acid (H3PM012O40) and its cesium salt (CS2HPM012O40) catalysts were the same as used in a previous study [9]. Pumice supported W03-based mixed oxide catalysts were the same as used in a previous study [10]. 

It should be noted that the catalytic activity falls markedly with an increase in the time-on-stream. Similar falls in catalytic activity were also observed in the cases of the other W-based mixed oxides, such as W-Sn, W-Ti, and W-Mo. It was also found that the deactivated catalysts can easily be regenerated by a heat-treatment at 500°C in air for 1 h.

Physical properties of binary or ternary Ru/Ir based mixed oxides with valve metal additions is still a field which deserves further research. The complexity of this matter has been demonstrated by Triggs [49] on (Ru,Ti)Ox who has shown, using XPS and other techniques (UPS, Mossbauer, Absorption, Conductivity), that Ru in TiOz (Ti rich phase) adopts different valence states depending on the environment. Possible donors or acceptors are compensated by Ru in the respective valence state. Trivalent donors are compensated by Ru5+, pentavalent acceptors will be compensated by Ru3+ or even Ru2+. In pure TiOz ruthenium adopts the tetravalent state. The surface composition of the titanium rich phase (2% Ru) was found to be identical to the nominal composition. 

It is well known that dense ceramic membranes made of the mixture of ionic and electron conductors are permeable to oxygen at elevated temperatures. For example, perovskite-type oxides (e.g., La-Sr-Fe-Co, Sr-Fe-Co, and Ba-Sr-Co-Fe-based mixed oxide systems) are good oxygen-permeable ceramics. Figure 2.11 depicts a conceptual design of an oxygen membrane reactor equipped with an OPM. A detail of the ceramic membrane wall...

A number of Mo- or Sb-based mixed oxides was compared by Germain and Perez [135] using a pulse reactor. The main results with respect to activities and selectivities are collected in Tables 15 and 16. 

Vapor-phase oxidation of toluene to benzaldehyde was studied with various Mo-, U—, and Sb-based mixed-oxide catalysts. The selectivity to benzaldehyde fell with increasing the toluene conversion. The best performances were obtained with Mo-P and U-Mo oxide catalysts the one-pass yield of benzaldehyde reached 40 mol% with a selectivity of about 60 mol%. The catalytic activity of the U-Mo oxides was more stable than that of the Mo-P oxides. The effects of the reaction variables on both the rate and selectivity were also studied. 

The catalysts used in this study were Mo-, U-, and Sb-based mixed-oxides.
