Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The syngas quality, composition, and throughput are suitable for produce a wide range of chemicals.

The disclosure relates to methods, systems, and apparatus arranged and designed for converting non-methane hydrocarbon gases into multiple product gas streams including a predominately hydrogen gas stream and a predominately methane gas steam. Hydrocarbon gas streams are reformed, cracked, or converted into a synthesis gas stream and methane gas stream by receiving a volume of flare gas or other hydrocarbon liquid or gas feed, where the volume of hydrocarbon feed includes a volume of methane and volume of nonmethane hydrocarbons. The hydrogen contained in the syngas may be separated into a pure hydrogen gas stream. A corresponding gas conversion system can include a super heater to provide a hydrocarbon feed/steam mixture, a heavy hydrocarbon reactor for synthesis gas formation, and a hydrogen separator to recover the hydrogen portion of the synthesis gas.

A synthesis gas production process from CO.sub.2 and H.sub.2O with a co-electrolysis, wherein the CO.sub.2 and CH.sub.4 content of the produced gas is reduced on the cathode side.

The present invention concerns a sorption-enhanced water-gas shift (SEWGS) process for the formation of a CO.sub.2 product stream and an H.sub.2 product stream, comprising (a) a reaction step, wherein a feed gas comprising CO.sub.x, wherein x=1-2, and H.sub.2O is fed into a SEWGS reactor containing a catalyst and sorbent material capable of adsorbing CO.sub.2, thereby forming the H.sub.2 product stream and a sorbent material loaded with CO.sub.2; (b) a rinse step, wherein steam is fed to the SEWGS reactor, thereby establishing a pressure in the range of 5-50 bar; (c) a pre-blowdown step, wherein the pressure in the SEWGS reactor is reduced to establish a blowdown pressure in the range of 0.5-1.5 times the partial pressure of CO and CO.sub.2 in the feed gas of step (a); (d) a blowdown step, wherein the pressure in the SEWGS reactor is reduced to the regeneration pressure in the range of 1-5 bar, thereby releasing at least part of the CO.sub.2 from the loaded sorbent material, thereby forming the CO.sub.2 product stream; and (e) a purge step, wherein steam is fed to the SEWGS reactor, thereby releasing further CO.sub.2 molecules from the SEWGS reactor, wherein the off gas released from the reactor during step (c) is collected separately from the CO.sub.2 product stream released from the reactor during step (d). The separate collection of the off gas of pre-blowdown step (c) affords a highly efficient process with excellent CO.sub.2 purity and carbon capture ratio.

A process and associated system for generating a hydrogen product from a feed gas stream comprising hydrogen sulfide. The process includes thermally decomposing hydrogen sulfide present in the feed gas stream into hydrogen gas and elemental sulfur in a thermal decomposition unit. The thermal decomposition unit includes a reactor vessel with a porous susceptor disposed and retained therein and a microwave generation unit positioned and configured to deliver microwave energy to the porous susceptor. Thermally decomposing hydrogen sulfide in the thermal decomposition unit includes directing microwave energy into the porous susceptor to raise the temperature of the porous, susceptor to greater than 1,000° C. and then passing the hydrogen sulfide through the porous susceptor to thermally decompose the hydrogen sulfide and generate a thermal decomposition unit effluent. The process further includes separating the thermal decomposition unit effluent into a sulfur fraction, a hydrogen rich fraction, and a hydrogen sulfide fraction.

Carbon capture of carbon dioxide (CO.sub.2) gives an extracted CO.sub.2 stream that is reacted with hydrogen to produce methanol (MeOH), which can in turn be fed to catalytic production of olefins such as ethylene and propylene to give an integrated process.
