The invention relates to Chydrocarbon conversion. More particularly, the invention relates to separating a vapor phase product and a liquid phase product from a heated mixture that includes steam and Chydrocarbons, catalytically cracking the liquid phase product and steam cracking the vapor phase product.

Process for Chydrocarbon conversion

The invention relates to a process of alkylating aromatic hydrocarbons, and more particularly a process of making paraxylene by alkylation of benzene and/or toluene with methanol and/or dimethyl ether, and to an apparatus for carrying out said process, the improvement comprising staged injection of one of the reactants, with the stages separated by structured packing so as to minimize at least one of gas phase back-mixing, by-pass phenomena, and gas bubble size.

Fluid bed reactor with staged baffles

This invention relates to the catalytic cracking of a hydrocarbon feed. In particular, this invention relates to an apparatus and process utilizing a catalyst stripper section of a fluid catalytic cracking (FCC) reactor with chordal trays designed to provide improved stripping of hydrocarbons from spent FCC catalyst in an FCC reactor stripping zone.
