Abstract:
A process for ortho-para-hydrogen conversion characterized by the use as a catalyst of a sulphur-containing semiconductive polymer produced by the dehalogenation of a poly(tetrahalophenylene sulphide) in the presence or absence of an organic solvent at 150.degree.-500.degree. C.
Abstract:
A gas mixer and reactor is provided which includes an elongated gas flow chamber with a nozzle arrangement at its inlet end for passing a first gaseous reactant into the interior of the chamber, toward the outlet of the chamber from points uniformly about the inner periphery of the chamber, and an annular nozzle arrangement near the outlet of the gas flow chamber for directing another gaseous reactant, or reactants, through the outlet of the gas flow chamber and into a thermal reaction chamber which communicates with the outlet of the gas flow chamber. In this manner controlled amounts of gaseous reactants may be thoroughly admixed and reacted to produce an atmosphere of desired composition. Atmospheres for kilns having controlled amounts of free hydrogen, carbon monoxide, oxygen, or carbon for example, are produced by burning controlled ratios of fuel, air and in some cases an inert gas, mixed by the reactor.
Abstract:
Process for the continuous production of carbon monoxide and hydrogen as separate products utilizing as raw materials water and carbon, such as coal, char, coke and other carbonaceous materials. Hydrogen is produced by oxidation of phosphorus with steam in the first step of the process. The resulting phosphorus oxides are reduced with carbon in the second step of the process to produce carbon monoxide and elemental phosphorus which latter is recycled to the first step. Essentially no phosphorus is consumed.
Abstract:
Graphite impregnated with at least one valve metal oxide such as zirconium oxide, tantalum oxide, titanium oxide, aluminum oxide or molybdenum oxide alone or optionally co-deposited with an oxide of a metal of the eighth group of the periodic table which is useful in an amalgam denuder and a process for the preparation and use of the said impregnated graphite to decompose an alkali metal amalgam to mercury and alkali metal hydroxide.
Abstract:
IN THE EXTRACTION OF DEUTERIUM FROM HYDROGEN IN A BITHERMAL PROCESS FOR THE PRODUCTION OF HEAVY WATER, A STREAM CONTAINING A FIRST LIQUID AMINE WITH UP TO FIVE CARBON ATOMS PER MOLECULE IS USED AS THE EXCHANGE LIQUID IN ONE OF THE EXCHANGE REGIONS, AND STREAM CONTAINING A SECOND LIQUID AMINE WITH UP TO FIVE CARBON ATOMS PER MOLECULE OR AMMONIA IS USED AS THE EXCHANGE LIQUID IN THE OTHER EXCHANGE REGION, AND DEUTERIUM EXCHANGE BETWEEN THE TWO EXCHANGE LIQUID STREAMS IS CAUSED TO OCCUR UNDER CONDITIONS SUCH THAT COUNTERCURRENT CONTACT IS POSSIBLE, FOR EXAMPLE SUCH THAT ONE OF THE EXCHANGE LIQUID EXISTS SUBSTANTIALLY AS A VAPOR AND A PORTION OF THE FIRST OR SECOND EXCHANGE LIQUID ENRICHED IN DEUTERIUM IS SEPARATED AFTER EXCHANGE BETWEEN THE TWO LIQUID. THE AMINE MAY BE PRIMARY ALIPHATIC MONOAMINE OR DIAMINES.
Abstract:
The subject invention is a process and device to effectively remove combustion pollutants under oxygen conditions greater than six volume percent. Microwave enhancement of oxidation/reduction catalysis is selectively employed in a multiple step process. However some of the steps do not utilize microwaves as they convert NO to NO.sub.2 by employing a conventional oxidation catalyst, and which then in a subsequent step which does employ microwaves uses a reducing agent to undergo catalytic reduction to N.sub.2.
Abstract:
A process for promoting heterogeneous chemical and physical reactions in a gas stream using a casing which is substantially liquid and gas tight having a gas inlet in one end and a gas outlet in the other end; nozzle means within the casing having an entry toward said one end in communication with the gas inlet and an outlet toward said other end, said nozzle means having an effective cross-sectional area of about 2 to about 64 times the effective cross-sectional area of the outlet and the mean angle of convergence of the nozzle being about 6.degree. to about 20.degree.; means in the casing for introduction of reactant liquids and solids into the gas stream before said nozzle means; means for removing liquid and particulate matter from said other end of the casing following desired reaction; and means for separately removing the gas from said other end of the casing. The process of this invention is especially useful in providing a self-cleaning, non-clogging system for inducing high reaction kinetics without the normally required high turbulence and concurrent pressure drop of a scrubber; or packing to provide surface area such as used in conventional absorber.
Abstract:
A thermochemical process for producing hydrogen comprises the step of reacting CoO with BaO or Ba(OH).sub.2 in the presence of steam to produce H.sub.2 and novel double oxides of Ba and Co having the empirical formulas BaCoO.sub.2.33 and Ba.sub.2 CoO.sub.3.33. The double oxide can be reacted with H.sub.2 O to form Co.sub.3 O.sub.4 and Ba(OH).sub.2 which can be recycled to the original reaction. The Co.sub.3 O.sub.4 is converted to CoO by either of two procedures. In one embodiment Co.sub.3 O.sub.4 is heated, preferably in steam, to form CoO. In another embodiment Co.sub.3 O.sub.4 is reacted with aqueous HCl solution to produce CoCl.sub.2 and Cl.sub.2. The CoCl.sub.2 is reacted with H.sub.2 O to form CoO and HCl and the CoO is recycled to the initial reaction step. The Cl.sub.2 can be reacted with H.sub.2 O to produce HCl. HCl can be recycled for reaction with Co.sub.3 O.sub.4.
