Disclosed herein are systems and processes for the conversion of a methane feedstock to Chydrocarbons.

Small channel short fixed bed adiabatic reactor for oxidative coupling of methane

Methods of performing a startup of an oxidative coupling of methane reaction to produce C+ hydrocarbons are described. The methods can include incrementally varying startup parameters of the oxidative methane reactor and using the feed gas as a coolant such that high C+ hydrocarbon selectivity is achieved.

Ignition of oxidative coupling of methane while reducing ratio of methane to oxygen

A method of autothermal oxidative coupling of methane (OCM) utilizes introducing a methane-containing feedstock and an oxygen-gas-containing feedstock into a reactor () as a flowing mixture () with a space time of 500 ms or less. The reactor () contains a catalyst bed () of an OCM catalyst that contacts the flowing mixture and wherein the catalyst bed () has a heat Peclet number (Pe) of from 5 or less, a mass Peclet number (Pe) of from 5 or more, and a transverse Peclet number (P) of from 1 or less while contacting the flowing mixture. The methane and oxygen of the feedstocks are allowed to react within the reactor () to form methane oxidative coupling reaction products. A reactor () for carrying out the OCM reaction is also disclosed.

Method and reactor for oxidative coupling of methane

Methods of performing a startup of an oxidative coupling of methane reaction to produce C2+ hydrocarbons are described. The methods can include incrementally varying startup parameters of the oxidative methane reactor and using the feed gas as a coolant such that high C2+ hydrocarbon selectivity is achieved.

Oxidative coupling of methane at near ambient feed temperature

Subterranean treatment formation using a model which takes into account the pore level physics by coupling the local pore scale phenomena to the macroscopic variables (Darcy velocity, pressure and reactant cup-mixing concentration) through the structure-property relationships (permeability-porosity, average pore size-porosity and interfacial area-porosity) and the dependence of the fluid-solid mass transfer coefficient and fluid phase dispersion coefficient on the evolving pore scale variables (average pore size, local Reynolds and Schmidt numbers).

Subterranean formation treatment methods using a darcy scale and pore scale model

Disclosed are methods of modeling stimulation treatments, such as designing matrix treatments for subterranean formations penetrated by a wellbore, to enhance hydrocarbon recovery. The modeling methods describe the growth rate and the structure of the dissolution pattern formed due to the injection of a treatment fluid in a porous medium, based on calculating the length scales for dominant transport mechanism(s) and reaction mechanism(s) in the direction of flow land the direction transverse to flow l. Methods of the invention may further include introducing a treatment fluid into the formation, and treating the formation.
