Abstract
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.
