  • Patent number: 8106248
    Abstract: In one aspect, the inventive process comprises a process for pyrolyzing a hydrocarbon feedstock containing nonvolatiles in a regenerative pyrolysis reactor system. The process comprises: (a) heating the nonvolatile-containing hydrocarbon feedstock upstream of a regenerative pyrolysis reactor system to a temperature sufficient to form a vapor phase that is essentially free of nonvolatiles and a liquid phase containing the nonvolatiles; (b) separating said vapor phase from said liquid phase; (c) feeding the separated vapor phase and methane to the pyrolysis reactor system; and (d) converting the methane and separated vapor phase in said pyrolysis reactor system to form a pyrolysis product. In another aspect, the invention includes a separation process that feeds multiple pyrolysis reactors.

  • Publication number: 20110172448
    Abstract: A cost effective process is presented for carrying out catalytic, in particular also exothermic, endothermic or autothermal reactions with optimum yield and selectivity. The system used is a wall-flow monolith which forces a flow from the inlet channel through the porous wall into the outlet channel by reciprocal closure of the gas channels. This is operated such that mass transfer and heat transport are determined virtually exclusively by convection, and diffusion-related thermal conduction phenomena can be neglected.
