SINGLE-LOOP OCTANE ENRICHMENT

The present invention provides apparatuses and processes for producing high octane fuel from synthesis gas. The process combines transalkylation and zeolite-forming/aromatization in conjunction with a single recycle loop configuration in order to effectively promote the fuel quality, particularly octane rating. The process involves adding a step for enriching octane of the fuel coming from the single recycle loop process. Preferably, the enrichment step takes place in an octane enrichment reactor containing two different catalysts, a zeolite-forming/aromatization catalyst followed by a transalkylation catalyst. The final fuel product preferably has an octane of about 92 to about 112.

METHOD FOR PRODUCING GASOLINE WITH LOW SULPHUR AND MERCAPTAN CONTENT

A process for the treatment of a gasoline containing sulfur compounds and olefins includes the following stages: a) hydrodesulfurization in the presence of a catalyst having an oxide support and an active phase having a metal from group VIB and a metal from group VIII, b) hydrodesulfurization at a higher temperature than that of stage a) and in the presence of a catalyst having an oxide support and an active phase with at least one metal from group VIII, c) separation of H.sub.2S formed, d) hydrodesulfurization at a low hydrogen/feedstock ratio and in the presence of a hydrodesulfurization catalyst having an oxide support and an active phase having a metal from group VIB and a metal from group VIII or an active phase with at least one metal from group VIII, and e) further separation of H.sub.2S formed.

REGENERATION OF ACIDIC IONIC LIQUID WITHOUT ADDITION OF A HYDROGENATION CATALYST

We provide a process for regenerating a spent acidic ionic liquid, comprising contacting the spent acidic ionic liquid with hydrogen and without an addition of a hydrogenation catalyst; wherein a conjunct polymer content is decreased in the spent acidic ionic liquid to produce regenerated acidic ionic liquid. We also provide a process for making an alkylate gasoline blending component, comprising: a) alkylating a mixture of isoparaffins and olefins using an acidic ionic liquid and an alkyl halide or a hydrogen halide, wherein a conjunct polymer accumulates in a spent acidic ionic liquid; and b) feeding the spent acidic ionic liquid and a hydrogen, and without an addition of a hydrogenation catalyst, to a regeneration reactor operated under selected hydrogenation conditions to produce a regenerated acidic ionic liquid that is used for the alkylating, wherein the conjunct polymer in the regenerated acidic ionic liquid is decreased by at least 50 wt %.

Syngas generation for gas-to-liquid fuel conversion
11453827 · 2022-09-27 · ·

A syngas generator is disclosed as an exothermic gas generator that can accommodate high combustion temperatures of a natural gas/oxygen flame. The generator includes four sections: a heavily insulated combustion chamber, a catalyst chamber, a spray chamber, and a heat exchanger. These four sections may be arranged in series and tightly bolted together to form a gas-tight system. Natural gas, oxygen and steam are supplied to a burner at the inlet end of the combustion chamber. This mixture is ignited and the resulting hot process gas is then fed into a catalyst bed where it reacts with the steam and is converted to carbon monoxide and hydrogen (syngas). The syngas is fed to a Fischer-Tropsch unit to create liquid fuel.
