Abstract: THE METHOD COMPRISES THE SQUENTIALY STEPS OF (1) PASSING AN INERT GAS THROUGH THE CATALYST BED AT A BED TEMPERATURE THAT IS BELOW THE INGNITION TEMPERATUTE OF COKE AND ANY ADDITIONAL NON-PUROPHORIC MATERIAL IN THE BED; AND (2) ADDING A CONTROLLED AMOUNT OF OSYGEN-CONTAINING GAS TO THE INERT GAS TO OXIDIZE THE PYROPHORIC MATERIAL. PREFERABLY, THE METHOD COMPRISES AN ADDITIONAL STEP OF MAINTAINING THE OXYGEN PARTIAL PRESSURE AT ABOUT 0.3 TO 1 ATMOSPHERE OF OXYGEN FOR A TIME THAT IS SUFFICIENT TO ELIMINATE ANY TEMPERATURE RISE THAT MAY OCCUR IN THE BED WHEN THE AMOUNT OF OXYGEN-CONTAINING GAS IS INCREASED.

Abstract: A CARBONIZED, UNSUPPORTED VANADIUM SULFIDE CATALYST IS REGENERATED WITH HYDROGEN SULFIDE OR ELEMENTAL SULFUR BY WAY OF A TWO-STAGE TREATMENT AT ELEVATED TEMPERATURES. THE FIRST STAGE IS EFFECTED AT TEMPERATURES ABOVE ABOUT 500*C., WHEREBY CARBON DISULFIDE IS FORMED, AND THE SECOND STAGE IS EFFECTED AT TEMPERATURES BELOW ABOUT 500* C., WHEREBY VANADIUM TETRASULFIDE IS FORMED. IN A PREFERRED METHOD, THE CARBONIZED CATALYST AND ELEMENTAL SULFUR ARE CONTACTED AND HEATED IN A HYDROGEN SULFIDE ATMOSPHERE. FURTHER, CARBON DISULFIDE MAY BE USED AT THE LOWER TEMPERATURE TO FORM THE VANADIUM TETRASULFIDE.

Abstract: A carbonized, unsupported nonstoichiometric vanadium sulfide catalyst is regenerated by way of a three-stage treatment at elevated temperatures. In the first stage, carbon is removed from the catalyst by contacting with elemental sulfur at an elevated temperature in the range of about 500* to about 1,000* C. The substantially carbon-free catalyst is treated with a mineral acid, or anhydrous HF, to dissolve metallic contaminants, and further treated in a third stage with elemental sulfur at a temperature in the range of 300* to about 500* C. to form vanadium tetrasulfide.
Abstract translation: 碳化的，未负载的非化学计量的硫化钒催化剂在升高的温度下通过三级处理再生。 在第一阶段，通过在约500℃至约1000℃的升高的温度下与元素硫接触从催化剂中除去碳。基本上不含碳的催化剂用无机酸或无水HF处理， 以溶解金属污染物，并在第三阶段用元素硫进一步处理，温度范围为300-约500℃，形成四硫化钒。

Abstract: A hydrocracking catalyst containing an Iron Group metal on a silica-aluming refractory oxide support is deactivated by contact with water vapor at elevated temperatures. The catalytic activity and stability are improved by treating the catalyst in the presence of sulfide with a gas comprising hydrogen and a fluorine compound at a temperature of about 250* to 550* C.

Abstract: Raney nickel catalysts which have been sulfur poisoned are regenerated by successive treatment first in an aqueous organic acid solution containing metal ions that form an insoluble sulfide in acid solutions, but which are soluble or decompose to soluble products and in an aqueous base solution. The catalyst is then separated and washed to remove traces of treating substances. The regenerated catalyst has an activity comparable to the freshly prepared catalyst.
