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.

Methods for processing hydrocarbon feed streams

Light olefins may be produced from hydrocarbons by a method including passing a hydrocarbon feed stream into one or more feed inlets of a reactor, using catalyst formulations or mixtures. Catalyst formulations may include multi-zeolite composite particles, or a mixture that is a physically mixed combination of separate particles of at least first composite particles of a first type of zeolite and second composite particles of a second type of zeolite. The reactor may include an upper reactor portion defining an upper reaction zone and a lower reactor portion defining a lower reaction zone. The catalyst may move in a generally downward direction through the upper reactor portion and the lower reactor portion, and the hydrocarbon feed stream may move in a generally upward direction through the lower reactor portion and upper reactor portion such that the hydrocarbon feed stream and the catalyst move with a counter-current orientation.
