Process of Alkylation of Isobutane with Olefins
The process for producing an alkylate is intended for use in the oil refining and hydrocarbon process industry. The process comprises reacting isobutane with an alkylation agent (an olefin) in the presence of a solid acidic catalyst and a C4+ solvent. Thus, a system is obtained, wherein the solid acidic catalyst is suspended in a solvent and the suspension is maintained by passing the feed stream through the catalyst-solvent system, thereby providing a uniform catalyst distribution throughout the entire volume and enabling the reaction to be carried out at low pressures.
HIGH CONVERSION AND SELECTIVITY ODH PROCESS
Ethane may be catalytically oxidatively dehydrogenated to ethylene at high conversions and high selectivity in a circulating fluidized bed (CFB) reactor in the presence of oxygen in the feed in an amount above the flammability limit. The reactor has an attached regeneration reactor to regenerate the catalyst and cycle back to the CFB.

Process for one-step conversion of lignocellulosic material to hydrocarbon products and catalyst for use in said process
A lignocellulosic starting material can be converted into an aqueous phase and a hydrocarbon phase in a one-step process by subjecting a mixture of the lignocellulosic starting material, an amorphous and unsupported sulfided nickel-molybdenum catalyst, and optionally a co-feed, to not less than a stoichiometric amount of hydrogen, elevated pressure and a temperature in the interval of 350-450 C. A novel catalyst for use in said process and a method for its production are also disclosed.
