The present invention relates generally to processes for hydromethanating a carbonaceous feedstock in a hydromethanation reactor to a methane-enriched raw product stream, and more specifically to processing of solid char by-product removed from the hydromethanation reactor to improve the carbon utilization and thermal efficiency and economics of the overall process by co-producing electric power and steam from the by-product char in addition to the end-product pipeline quality substitute natural gas.

Hydromethanation of a carbonaceous feedstock with improved carbon utilization and power generation

The present invention relates generally to processes for hydromethanating a carbonaceous feedstock in a hydromethanation reactor to a methane-enriched raw product stream, and more specifically to processing of solid char by-product removed from the hydromethanation reactor to improve the carbon utilization and thermal efficiency of the overall process and thereby lower the net costs of the end-product pipeline quality substitute natural gas.

Hydromethanation of a carbonaceous feedstock with improved carbon utilization

The present invention relates generally to processes for preparing an inorganic sodium and/or chlorine contaminated low-rank coal feedstock for combustion in a fluidized fuel combustor to generate steam and, desirably, co-generate electricity.

Use of contaminated low-rank coal for combustion

The present invention relates generally to processes for preparing agglomerated particulate low-rank coal feedstocks of a particle size suitable for reaction in a fluidized-bed reactor and certain other gasification reactors and, in particular, for coal gasification and combustion applications. The present invention also relates to an integrated coal hydromethanation process including preparing and utilizing such agglomerated particulate low-rank coal feedstocks.

A process is disclosed for removing highly deleterious non-basic nitrogen compounds upstream from an acid catalyzed thiophene alkylation process using adsorbents capable of adsorbing the non-basic nitrogen compounds.

Process for removal of sulfur from components for blending of transportation fuels

A new reactor apparatus that can be used to carry out chemical reactions in a fluidized catalyst bed at high temperatures with reduced afterburning or other undesirable downstream side reactions.

Reactor apparatus

A process for the recovery of unreacted ammonia from the effluent from a reaction zone used to produce acrylonitrile or methacrylonitrile comprising quenching the reactor effluent with an aqueous solution of ammonium phosphate in at least two stages, thereby capturing the ammonia component of the effluent. The captured ammonia may be recovered by heating the aqueous ammonium phosphate, which then may be recycled. Contaminants present in the aqueous ammonium phosphate may be removed, for example by solvent extraction or wet oxidation, prior to recycle.
