    • START-UP METHOD COMPRISES CONTACTING THE HYDROCRACKING CATALYST WITH A HYDROGEN-CONTAININ G GAS AT A PRESSURE BETWEEN ABOUT 0 AND ABOUT 2,500 P.S.I.G. AND A TEMPERATURE BETWEEN ABOUT 400* F. AND ABOUT 850* F.; COOLING THE CATALYST TO MINIMIZE CONVERSION OF HYDROCARBONS; CONTACTING THE CATALYST WITH A FIRST PRELIMINARY HYDROCARBON FEEDSTOCK HAVING LOW CONCENTRATIONS OF NITROGEN, SULFUR AND AROMATICS IN A MANNER THAT WILL NOT DELETERIOUSLY AFFECT THE CATALYST; INCREASING THE TEMPERATURE IN THE REACTION ZONE TO OBTAIN CONVERSION OF THE FIRST PRELIMINARY HYDROCARBON FEEDSTOCK TO LOWER-BOILING HYDROCARBONS; STOPPING THE FLOW OF THE FIRST PRELIMINARY HYDROCARBON FEEDSTOCK; AND CONTACTING THE CATALYST WITH A PRICIPAL PETROLEUM HYDROCARBON FEEDSTOCK. THE HYDROCRACKING CATALYST COMPRISES A HYDROGENATION COMPONENT ON A CO-CATALYTIC SUPPORT. THE PREFERRED SUPPORT COMPRISES ULTRASTABLE, LARGEPORE CRYSTALLINE ALUMINOSILICATE MATERIAL SUSPENDED IN A POROUS MATRIX OF AMORPHOUS SILICA-ALUMINA. THE PREFERRED HYDROGENATION COMPONENT COMPRISES A MIXTURE OF COBALT OXIDE AND MOLYBDENUM TRIOXIDE.

    • The safety, convenience and environmental acceptability of starting a two-stage hydrocracking process unit is increased by employing aqueous ammonia as a selective catalyst poison. The aqueous ammonia is injected into the recycle gas system of the hydrocracking process. The invention eliminates the possibility of forming a large airborne cloud of ammonia gas upon an accidental release of the ammonia stream as is possible with the injection of anhydrous ammonia. The invention also stabilizes the operation of the unit through the use of a maintenance injection rate sufficient to maintain an inlet ammonia content above about 40 ppm.
    • 通过使用氨水作为选择性催化剂毒物,可以提高启动两级加氢裂化处理单元的安全性,方便性和环境可接受性。 将氨水注入加氢裂化过程的循环气体系统中。 本发明消除了在注入无水氨的情况下意外释放氨气流时形成大量空气中的氨气的可能性。 本发明还通过使用足以维持高于约40ppm的入口氨含量的维护注入速率来稳定单元的操作。

    • A startup method for moving-bed reactors used in hydrocarbon conversion processes wherein the reactor is brought on-stream at full capacity while it contains less than a full loading of catalyst, and quantities of catalyst are intermittently added to the reactor while the hydrocarbons are being processed. Catalyst removal is then begun at a rate lower than the rate of catalyst addition and adjusted when the catalyst retention volume of the reactor becomes filled. The method is specifically adaptable to the hydrogenation of olefinic materials, the desulfurization of petroleum fractions and the production of liquid products from coal.

    • In the pressure testing of catalyst-loaded reactors with nitrogen gas at elevated temperatures, it is found that certain types of zeolite catalysts are substantially degraded in activity. The catalysts concerned comprises a Group VIII noble metal in an oxidized state, dispersed on a crystalline hydrogen zeolite, e.g., Y zeolite. It has now been discovered however that if such catalysts are first prereduced with a dilute, non-combustible mixture of nitrogen and hydrogen, damage on subsequent pressure testing with nitrogen is prevented or drastically reduced. Following pressure testing, the catalyst is activated by dehydration in a stream of hydrogen at elevated temperatures and pressures.
    • 在具有氮气的催化剂负载的反应器在升高的温度下的压力测试中,发现某些类型的沸石催化剂的活性显着降低。 所涉及的催化剂包括分散在结晶氢沸石如Y沸石上的氧化态的VIII族贵金属。 然而,现在已经发现,如果首先用稀释的,不可燃的氮气和氢气的混合物还原这种催化剂,则防止或大大降低随后用氮气进行的压力测试的损害。 经过压力测试,催化剂在高温和高压下在氢气流中脱水而活化。
