A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

A gasification system for the partial oxidation of a carbonaceous feedstock to at least provide a synthesis gas, comprising: a reactor chamber for receiving and partially oxidizing the carbonaceous feedstock, the reactor chamber having a reactor chamber floor; a quench chamber below the floor of the reactor chamber for holding a bath of liquid coolant; an intermediate section at said reactor chamber floor, the intermediate section having a reactor outlet opening through which the reactor chamber communicates with the quench chamber to conduct the synthesis gas from the reactor chamber into the bath of the quench chamber; at least one layer of refractory bricks arranged on and supported by the reactor chamber floor, the lower end section of the refractory bricks enclosing the reactor outlet opening and defining the inner diameter thereof; and a dip tube extending from the reactor outlet opening to the bath of the quench chamber, the dip tube having a widened top section.

A process for making recycle content ammonia by reacting hydrogen with nitrogen. At least a portion of the hydrogen is obtained directly or indirectly by molecular reforming a mixed plastic waste or pyrolysis product feedstock. The molecular reforming can be a steam reforming process or a partial oxidation process, such as a partial oxidation gasifier, to generate the syngas used as a source of hydrogen. The recycle content associated with the ammonia can be obtained from the mixed plastic waste, the recycle content in the pyrolysis product, such as pyoil or pygas, or the recycle content in the syngas or the purified hydrogen stream from the syngas.

A gasification process may include (a) introducing a liquid hydrocarbon feedstock and at least one of a dry feedstock or a first slurried feedstock into a reactor lower section, wherein the at least one dry feedstock or first slurried feedstock is introduced through two primary feed nozzles while the liquid hydrocarbon feedstock is introduced through at least two secondary feed nozzles; (b) partially combusting the feedstocks in the reactor lower section with a gas stream comprising an oxygen-containing gas or steam to evolve heat and form products comprising hot synthesis gas; (c) passing said hot synthesis gas from step (b) upward into a reactor upper section; (d) and introducing a second slurried feedstock into said reactor upper section, whereby heat from said hot synthesis gas supports reaction of the second slurried feedstock by pyrolysis and gasification reactions.
