We provide a process and apparatus for preparing a used ionic liquid catalyst for safe disposal, comprising hydrolyzing the used ionic liquid catalyst comprising an anhydrous metal halide with a basic solution at a temperature from &#x2212;20&#xb0; C. to 90&#xb0; C. to produce a hydrolyzed product, evolve a hydrogen halide gas, and dissolve the hydrogen halide gas into the basic solution.

Process and apparatus for safe disposal of used ionic liquid catalyst

We provide an extracted conjunct polymer naphtha (), comprising a hydrogenated conjunct polymer naphtha, from a used ionic liquid catalyst, having a final boiling point less than 246&#xb0; C. (475&#xb0; F.), a Bromine Number of 5 or less, and at least 30 wt % naphthenes. We also provide a blended alkylate gasoline () comprising the extracted conjunct polymer naphtha (), and integrated alkylation processes to make the extracted conjunct polymer naphtha () and the blended alkylate gasoline (). We also provide a method to analyze alkylate products, by determining an amount of methylcyclohexane in the alkylate products ().

Integrated alkylation process to make blended alkylate gasoline

We provide an alkylation process unit, comprising: a control system connected to an alkylation reactor, that enables the alkylation reactor to operate in both an alkylate mode that produces a gasoline blending component having a RON of 90 or higher and in a distillate mode that produces a second gasoline blending component having a RON of 85 or higher.

Alkylation process unit for producing high quality gasoline blending components in two modes

A process unit, comprising: a) an alkylation reactor; and b) a control system that enables the alkylation reactor to be operated in an alkylate mode and in a distillate mode; wherein the alkylation reactor can switch back and forth from operating in the alkylate mode to the distillate mode.

Process unit for flexible production of alkylate gasoline and distillate

We provide a process for producing high quality gasoline blending components, comprising: a) operating an alkylation reactor in an alkylate mode wherein a gasoline blending component is made having a RON of 90 or higher; and b) operating the alkylation reactor in a distillate mode wherein a second gasoline blending component and a distillate product is made, and wherein the second gasoline blending component has a RON of 85 or higher. Also, we provide an alkylation process unit, comprising: a control system connected to an alkylation reactor, that enables the alkylation reactor to operate in both an alkylate mode that produces a gasoline blending component having a RON of 90 or higher and in a distillate mode that produces a second gasoline blending component having a RON of 85 or higher.

Process for producing high quality gasoline blending components in two modes

Methods for starting and operating ionic liquid catalyzed hydrocarbon conversion processes and systems to provide maximum process efficiency, system reliability and equipment longevity may include: purging air and free water from at least a portion of the system; introducing at least one reactant into the at least a portion of the system; and re-circulating the at least one reactant through the at least a portion of the system, via at least one feed dryer unit, until the at least one reactant exiting the at least a portion of the system has a water content at or below a threshold value, prior to the introduction of an ionic liquid catalyst and/or additional reactant(s) and feeds into the system.

Extracted conjunct polymer naphtha

We provide a process and apparatus for preparing a used catalyst for disposal, comprising:

Hydrolysis of used ionic liquid catalyst for disposal

A process comprising adjusting a level of conjunct polymers in an ionic liquid catalyst between a low level that favors production of C+ products boiling at 137.8&#xb0; C. or below and a higher level that favors production of both C+ products boiling at 137.8&#xb0; C. or below and C+ products boiling above 137.8&#xb0; C.; wherein the adjusting is done in response to market demand. A process unit, comprising a reactor that operates with an ionic liquid catalyst comprising a low level or a higher level of conjunct polymers, and the alkylation reactor is switched between operating with the low and the higher levels in response to market demand. A process unit, comprising a reactor that operates in an alkylate mode and a distillate mode, and a catalyst regenerator that operates with varying severity to adjust the level of conjunct polymers in response to demand for gasoline or distillate.

Market driven alkylation or oligomerization process

A process for producing hydrocarbon products, comprising: a) operating a process unit in an alkylate mode wherein greater than 50 wt % of a Chydrocarbon stream from the process unit boils at 137.8&#xb0; C. or below, b) adjusting one or more process conditions in the process unit, and c) after the adjusting step, operating the process unit in a distillate mode wherein greater than 50 wt % of the Chydrocarbon stream from the process unit boils above 137.8&#xb0; C. Also, a process unit, comprising: a) an alkylation reactor; and b) a control system that enables the alkylation reactor to be operated in the alkylate mode and in the distillate mode; wherein the alkylation reactor can switch back and forth from operating in the alkylate mode to the distillate mode.
