A process for producing renewable distillate-range hydrocarbons is provided. The process includes dehydrating a renewable C2-C6 alcohol feedstock to produce an olefin, oligomerizing the olefin the presence of a halometallate ionic liquid catalyst to produce an oligomer product and hydrogenating the oligomer product or fractions thereof to produce saturated distillate-range hydrocarbons.

The present invention discloses a process for preparing perhydrofluorene or alkyl-substituted perhydrofluorene, comprising the steps of: (1) reacting a phenolic compound or an aromatic hydrocarbon compound or an aromatic ketone compound or an aromatic ether compound with a benzyl compound to carry out an alkylation reaction in the presence of a first catalyst, thereby to produce substituted or unsubstituted diphenyl methane, wherein the first catalyst is an acidic catalyst; and (2) reacting the substituted or unsubstituted diphenyl methane with hydrogen gas to carry out an hydrogenation reaction or a hydrodeoxygenation reaction, thereby to produce perhydrofluorene or alkyl-substituted perhydrofluorene, wherein the second catalyst is a physical mixture of a metal catalyst and an acidic catalyst or a metal catalyst loaded on an acidic catalyst.

The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose, starch, sugar) and ethylene in the presence of a catalyst. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF), which may be converted into para-xylene by cycloaddition of ethylene to DMF. Para-xylene can then be oxidized to form terephthalic acid.

A process of tuning a hydrocarbon product composition is described. The process involves selecting paraffins for reaction. The equilibrium constants for reactions of the selected paraffins can be used to select appropriate feed ratios, or an equilibrium composition as function of C/H molar ratio. A selected feed is reacted to obtain the product. Equilibrium product compositions and non-equilibrium product compositions can be obtained using the process.

A method for producing a linear hydrocarbon, including reacting a linear aliphatic aldehyde in the presence of at least one metal ion selected from the group consisting of a vanadium ion, a manganese ion, an iron ion, a cobalt ion, an iridium ion, a copper ion, and a thallium ion.

The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose) and ethylene in the presence of an acid, such as a Lewis acid. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF) and 2-methylfuran, which may be converted into para-xylene and toluene, respectively. In particular, para-xylene can then be oxidized to form terephthalic acid.

A method of implementing organic synthesis reactions uses a composition containing a metal catalyst originating from a calcined plant. The plants can be from the Brassicaceae, Sapotaceae and Convolvulaceae family, and the metal catalyst contains metal in the M(II) form such as zinc, nickel, manganese, lead, cadmium, calcium, magnesium or copper. Examples of the organic synthesis reactions include halogenations, electrophilic reactions, cycloadditions, transesterification reactions and coupling reactions, among others.

The present disclosure relates to preparation of liquid salt including but not limiting to ionic liquid and applications thereof. More particularly, the present disclosure provides a process for preparing ionic liquid which comprises reacting at least one electron-pair acceptor and at least one electron-pair donor to form an adduct, and reacting the adduct with at least one electron-pair acceptor to prepare said salt. The present disclosure also provides for applications of the ionic liquid prepared in the present disclosure.

A radio access network (RAN) configured to support real-time communications over a Long-Term Evolution (LTE) connection is described herein. When a request for a data transmission is received and a real-time communication session over the LTE connection is established, the RAN utilizes the LTE connection, not a New Radio (NR) connection, for the data transmission. When a request for a further real-time communication is received and there is an active data transmission session over the NR connection, the RAN performs at least one of ceasing to allocate traffic to the NR connection for downlink or reconfiguring the data transmission session to send data over the LTE connection.
