A method for producing an olefin and a monocyclic aromatic hydrocarbon of the present invention includes a dicyclopentadiene removal treatment step of removing dicyclopentadienes having a dicyclopentadiene skeleton from a feedstock oil which is a thermally-cracked heavy oil obtained from an apparatus for producing ethylene and which has a 90 volume % distillate temperature, as a distillation characteristic, of 390° C. or lower; and a cracking and reforming reaction step of obtaining a product containing an olefin and a monocyclic aromatic hydrocarbon by bringing the feedstock oil having a content of dicyclopentadienes adjusted to 10% by weight or less by treating a part or all of the feedstock oil through the dicyclopentadiene removal step into contact with a catalyst and reacting the feedstock oil.

A fluidized reforming process comprising a two stage fluidized reforming reactor is described. A naphtha stream flows upward through the two fluidized stages and contacts the catalyst forming a product stream and spent catalyst. The spent catalyst is separated from the product stream and the naphtha feed stream. Some of the spent catalyst is regenerated by contact with an oxygen-containing regeneration fluid to heat and reactivate the catalyst. The heated, regenerated catalyst forms at least a port of the catalyst stream for the process. A process for cyclizing paraffins or isomerizing cyclopentanes is also described. The process uses a chloride-free Pt/Ga-containing catalyst to form a cyclic aliphatic hydrocarbon or isomerizing a cyclopentane in the presence of the chloride-free Pt/Ga-containing catalyst to form a cyclohexane.

Embodiments of the present disclosure are directed to processes for aromatizing hydrocarbons includes contacting the hydrocarbons with a catalyst including at least two different metal modifiers dispersed on surfaces of a hydrogen-form medium-pore zeolite support. Each of the at least two different metal modifiers comprises a metal selected from the group consisting of IUPAC Groups 3-12, and lanthanide metals, and the catalyst is substantially free of gallium. Contacting the hydrocarbons with the catalyst causes a least a portion of the hydrocarbons to undergo a chemical reaction to form aromatic hydrocarbons.
