    Abstract: Improved process for producing chlorine molecules comprises oxidn. of hydrochloric acid with molecular oxygen. This oxidn. process is carried out in the presence of a catalyst, and chromium oxide. The chromium oxide is prepd. by (1) chromium oxide is carried on a silicon oxide carrier which has a porosity of 0.3-1.8 cc/g, with amt. of carried chromium oxide evaluated as chromia, of 20-90 wt.%, (2) carried chromium oxide is heat treated at 450-700 deg.C. The chromium oxide catalyst is obtd. by contacting aq.soln. of chromate anhydride or chromium salt with silicon oxide, and then drying and heat treating. The oxidn. reaction is carried out in a flow process at a temp. 350-430 deg.C in the presence of molecular oxygen. The molecular ratio of oxygen to HCl lies between 0.25-5 and the flow rate of HCl is 200-1800 Nl/Kg catalyst/hour. The radius of the porous holes in the silicon oxide carrier lies between 20 and 300 Angstroms.

    Abstract: Methanol is decomposed in the presence of a catalyst containing chromium oxide and zinc oxide as main components and containing a compound of at least one element selected from alkali metals, alkali earth metals and lanthanides, while contents of iron and nickel in the catalyst are each maintained at 0.5% by weight or less. This process is characterised by (1) being excellent in stability at high temperatures, (2) preventing the catalyst from deteriorating, (3) inhibiting the production of by-products, and (4) obtaining a gas in which the CO/H2 ratio is high.

    Abstract: In the process of producing chlorine by oxidizing hydrogen chloride with molecular oxygen, activity of the catalyst can be maintained for a long period with a high conversion ratio under high space velocity of gaseous raw materials without using additives as conventional methods, in the presence of a crystalline chromic oxide catalyst obtained by supporting relatively large amount of chromic oxide on a silicon oxide carrier having a specified pore volume.
