摘要： A method for carrying out a chemical reaction includes using a reactor arrangement in which reaction tubes arranged in a reactor vessel are heated to a reaction tube temperature level between 400° C. and 1,500° C. during a reaction period using radiant heat provided by means of one or more electric heating elements arranged in the reactor vessel. In at least a part of the reactor vessel in which the heating elements are provided, a gas atmosphere is provided during the reaction period, which gas atmosphere has a defined volume fraction of oxygen.

摘要： A method for preparing a hydrocracking catalyst comprising: (i) providing a shaped body comprising a zeolite and a binder, wherein the shaped body has been obtained by shaping, calcination and cooling, wherein the zeolite is ZSM-5 having a silica (SiO2) to alumina (Al2O3) molar ratio of 25-75; (ii) optionally drying the shaped body at a temperature of 100-300° C. for a period of at least 1 hour; (iii) depositing a hydrogenation metal on the shaped body by an impregnation for a period of at most 2 hours such that the amount of the hydrogenation metal is 0.010-0.30 wt % with respect to the total catalyst; (iv) optionally rinsing the metal deposited shaped body with water; and (v) heat-treating the metal deposited shaped body in air at a temperature of 250-300° C. for a period of 1-5 hours; wherein the catalyst comprises a total of less than 0.05 wt % sodium and cesium.
