A hydrocarbon feed stream may be processed by a method that may include catalytically cracking a hydrocarbon feed stream in a counter-current reactor to produce a first effluent stream, and processing a portion or all of the first effluent stream by at least one or more separations. The at least one or more separations may form at least a second effluent stream including at least 95 wt. % C-Chydrocarbons, and a third effluent stream including at least 95 wt. % of ethane, propane, or a combination thereof. In some embodiments, the method may further include catalytically cracking a portion or all of the second effluent stream in a second reactor to form a second reactor effluent stream, combining a portion of all of the second reactor effluent stream with the first effluent stream, steam cracking a portion or all of the third effluent stream to form a steam cracked effluent stream, and combining a portion or all of the steam cracked effluent stream with the first effluent. In other embodiments, the method may further include passing a portion or all of the second effluent stream to the counter-current reactor, steam cracking a portion or all of the third effluent stream to form a steam cracked effluent stream, and combining a portion or all of the steam cracked effluent stream with the first effluent stream.

A method of making a boronated zeolite catalyst includes preparing an initial slurry comprising water, a shape selective zeolite, boric acid, and a weak acid selected from the group consisting of oxalic acid, citric acid, and oxalic acid and citric acid, hydrothermally treating the initial slurry at a temperature of from 70° C. to 90° C. to produce a hydrothermally treated slurry comprising dealuminated zeolite particles, adjusting the pH of the hydrothermally treated slurry to an intermediate pH of from 8 to 9 to produce a basic slurry, after adjusting the pH to the intermediate pH, hydrothermally treating the basic slurry at a temperature of from 70° C. to 90° C. to produce a boronated zeolite slurry, removing liquids from the boronated zeolite slurry to produce a boronated zeolite filtrate, and drying and calcining the boronated zeolite filtrate to produce the boronated zeolite catalyst.
