    摘要： A PROCESS FOR THE REGENERATION OF SULFUR DEACTIVATED CATALYSTS BY CONTACT, OR REACTION, OF THE SAID CATALYST WITH METHANE. A CATALYST, OR CATALYST COMPOSITE, WHICH HAS BEEN POISONED, AND THEREBY DEACTIVATED, BY CONTACT WITH SULFUR IN SUFFICIENT CONCENTRATION AND EXPOSED TO OXYGEN TO FORM THE SULFATE, CAN BE REGENERATED BY CONTACT WITH METHANE. SUCH CATALYST REGENERATION TECHNIQUE FINDS PARTICULAR UTILITY IN SEMIREGENERATIVE TYPE REFORMING PROCESSES. REFORMING CATALYSTS, PARTICULARLY CATALYST COMPOSITES WHICH CONTAIN ALUMINA, E.G. NOBLE METAL ON AN ALUMINA BASE SUCH AS PLATINUM-ON-ALUMINA, WHICH HAS BEEN DEACTIVATED BY SULFUR COMPOUNDS CAN BE REGENERATED BY CONTACT WITH METHANE AT TEMPERATURES RANGING GENERALLY FROM ABOUT 700*F. TO ABOUT 1050*F., AND AT PRESSURES RANGING FROM ABOUT 15 P.S.I. TO ABOUT 300 P.S.I.

    摘要： The invention relates to a not as yet considered kind of corrosion of products made of silicon carbide working in elevated temperatures and discloses a method of preventing this kind of corrosion which begins already at the moderate temperature of about 550.degree. C. and is caused by the formation of carbon monoxide in the pores of the interior of the silicon carbide products in conditions of limited penetration of oxygen into these pores. The disclosed method of preventing this kind of corrosion consists in shielding part of the surface of the mentioned silicon carbide products by perfectly gastight shields or by a protective atmosphere or inversely in enhancing the access of oxygen into the pores of the mentioned product thus diluting the carbon monoxide being formed, by enlarging the number of open pores so that an open porosity of the product exceeding about 40 percent is reached or by providing uniformly distributed channels in the silicon carbide product the total volume of channels being at least about 10 percent of the outer volume of the product.

    摘要： Supported iridium-containing hydrocarbon conversion catalysts which are at least partially deactivated due to the deposition of carbonaceous residues thereon during contact with hydrocarbons are regenerated by contacting the catalyst, prior to contact with oxygen at elevated temperature, with a chlorine-containing reagent to increase the catalyst chlorine content to at least 1.0 wt. %., based on anhydrous catalyst, and thereafter contacting the catalyst with a gaseous mixture containing oxygen, a chlorine containing reagent, and water at a temperature of about 750* to 1000*F. for a time sufficient to burn at least a portion of the carbonaceous residues from the catalyst.

    摘要： A HALOGENATED REFORMING CATALYST COMPRISING PLATINUM WHICH HAS BECOME DEACTIVATED WITH CARBONACEOUS DEPOSITS DURING ON-STREAM REFORMING IS REGENERATED BY THE COMBINATION OF (1) REMOVING CARBONACEOUS MATERIAL BY BURNING WITH AN OXYGEN CONTAINING GAS UNDER CONDITIONS TO AVOID HEAT DAMAGE TO THE CATALYST, (2) HEATING THE CATALYST ITH AIR TO A TEMPERATURE OF ABOUT 900*F, (3) SELECTIVELY CHLORINATING EACH CATALYST BED WITH A MOISTURE SATURATED AIR STREAM TO A PREDETERMINED CHLORIDE LEVEL, (4) REDUCING THE CHLORIDED CATALYST WITH HYDROGEN RICH GAS FOR A PERIOD OF TIME IN THE RANGE OF 1 TO 4 HOURS, (5) ADDING SULFUR TO EACH CATALYST BED THEROETICALLY SUFFICIENT TO SULFIDE THE PLATINUM COMPONENT OF THE CATALYST AND (6) INITIATING ON-STREAM REFORMING OF NAPHTHA IN THE PRESENCE OF ADDED HYDROGEN SULFIDE.
