Abstract: 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.

Abstract: A method to produce olefins may include supplying a hydrocarbon feed to an outer tube of a thermal energy recovery assembly; heating the hydrocarbon feed in the outer tube of the thermal energy recovery assembly to output a preheated hydrocarbon feed; supplying the preheated hydrocarbon feed to an electrically powered cracking furnace comprising a reaction zone to heat the preheated hydrocarbon feed; cracking the preheated hydrocarbon feed in the reaction zone of the electrically heated cracking furnace using heat generated by electricity to output hot reactor effluent comprising cracked hydrocarbons and olefins; supplying the hot reactor effluent to an inner tube of the thermal energy recovery assembly; and cooling the hot reactor effluent in the inner tube of the thermal energy recovery assembly by transferring heat to the hydrocarbon feed.

Abstract: An electrically powered furnace and related methods may include an electrically powered furnace having an output of at least one megawatt with a control system; a furnace housing comprising one or more housing walls at least partially defining an interior volume; a plurality of heating zones within the interior volume; and a plurality of heated tubes extending in the interior volume. A method may include providing the feed to the electrically powered furnace; and algorithmically adjusting the output of the one or more heating elements for each of the plurality of heating zones to heat the feed to a desired temperature while maintaining temperatures of the one or more heating elements within predetermined parameters.

Abstract: An electrically powered furnace may include a furnace housing and heating elements extending in the furnace housing. The furnace also may include heating tubes extending in the interior volume, and each of the heating tubes may define an interior passage positioned to receive and heat the feed as the feed passes through the interior passage. The heating tubes may be positioned in the furnace housing to receive heat radiated from the heating elements, and the heating tubes may be arranged in one or more of at least two rows or at least two columns and such that each of the heating tubes is substantially equidistant from three or more of the heating elements. A method may include supplying a feed to the heating tubes, heating the heating tubes via the heating elements, and heating the feed via as the feed passes through the heating tubes.
