A bio-oil reactor leverages chemically recalcitrant lignocellulosic biomass using a moderate temperature molten-salt based process to unlock hydrocarbon content having the potential to substantially supplement demand for petroleum based fuels and chemicals. Bio-oil is a precursor to production of other chemicals and hydrocarbons, and can be refined as an effective replacement to conventional petroleum products and fossil fuels. A disclosed approach employs Molten-Salt Pyrolysis (MSP), for the efficient and economical production of such precursor chemicals directly from whole biomass under moderate conditions (400 C., 1 atm.). Lignocellulosic biomass, freely available in renewable wood and plant products, undergoes a moderate temperature heating process in a eutectic molten salt mixture to generate a condensable vapor of the precursor or platform chemicals.

The present invention relates to a device and a method for low-temperature pyrolysis, wherein: waste tire chips are continuously supplied; since a pneumatic method of an intake method and a blowing method is adopted, the waste tire chips may be quickly fed (supplied) by a simple method, and only the waste tire chips may be supplied into a pyrolysis reactor but the inflow of air thereinto may be fundamentally blocked, thereby increasing the pyrolysis efficiency of the pyrolysis reactor and preventing the explosion reaction thereof; and unlike the prior art, a mechanical conveyor supply method is not used, and thus waste tire chip supply equipment can be miniaturized and modularized, thereby enabling the compact design of the pyrolysis equipment, facilitating a pyrolysis operation, facilitating maintenance, and significantly reducing the site area of the pyrolysis equipment or the cost of manpower input for supplying waste tire chips.

A supported catalyst for depolymerizing polymers and methods for making and using such catalyst. The supported catalyst comprises tungsten species supported on an alumina support, a molybdenum species supported on a smectite clay support, or a combination thereof. The supported catalyst is prepared by dissolving a tungstate salt or a molybdate salt in a solvent to form a first solution comprising cations and metal oxoanions, adding a Brnsted-Lowry acid to the first solution to form a second solution comprising a metal oxo acid, and contacting a support material with the second solution, wherein the support material is an alumina or a smectite clay, respectively. A mixture of a polyolefin-based feed stream and the supported catalyst can be added to a pyrolysis reaction zone under depolymerization conditions in the absence of oxygen to form a first vapor stream and first liquid stream comprising one or more olefin monomers.

Proposed are a pyrolysis reactor and an apparatus having the same for recovering carbon fiber and glass fiber. The pyrolysis reactor includes a casing, at least one movement module, and at least one stirring module. The movement module includes a spiral wing mounted on an inner wall of the casing and deployed in a longitudinal direction of the casing. The stirring module includes a plurality of plate-shaped swirlers mounted perpendicularly on the inner wall of the casing the casing so that each of the swirlers extends in the longitudinal direction of the casing. The stirring module is arranged alternately with the movement module. The movement module moves a waste composite material within the casing, and the stirring module mixes the waste composite material with hot air within the casing. Heat is effectively transferred to the waste composite material by the stirring module, decreasing time required for a pyrolysis process.
