Abstract:
The present disclosure provides a method for preparing hydrogen-rich gas by solid organics. For example, solid organic raw materials are heated in a pyrolysis reaction device to perform pyrolysis reaction, and gaseous product generated from the pyrolysis reaction performs gasification with steam in a moving bed gasification reaction device to generate hydrogen-rich product. The present disclosure also provides a system for preparing hydrogen-rich gas by solid organics, and the system may include a solid heat carrier grading-dedusting device; a pyrolysis reaction device; a moving bed gasification reaction device; and a riser and combustion reactor. The present disclosure may operate at atmospheric pressure, and the technology is simple and suitable for the gasification and co-gasification of various high-volatile solid organics, such as raw materials containing a relatively large amount of moisture, mineral substance, and sulfur content.
Abstract:
This invention is a continuous retorting process for various high molecular weight organic materials, including oil shale, that yields an enhanced output of liquid product. The organic material, mineral matter, and an acidic catalyst, that appreciably adsorbs alkenes on surface sites at prescribed temperatures, are mixed and introduced into a pyrolyzer. A circulating stream of olefin enriched pyrolysis gas is continuously swept through the organic material and catalyst, whereupon, as the result of pyrolysis, the enhanced liquid product output is provided. Mixed spent organic material, mineral matter, and cool catalyst are continuously withdrawn from the pyrolyzer. Combustion of the spent organic material and mineral matter serves to reheat the catalyst. Olefin depleted pyrolysis gas, from the pyrolyzer, is enriched in olefins and recycled into the pyrolyzer. The reheated acidic catalyst is separated from the mineral matter and again mixed with fresh organic material, to maintain the continuously cyclic process.
Abstract:
A fast pyrolysis heat exchanger system for economically and efficiently converting biomass and other combustible materials into bio-oil. The system employs multiple closed loop tubes situated inside the heat exchanger. As a granular solid heat carrier is deposited at the top of the heat exchanger and caused to move downwardly therethrough, heat is transferred from the tubes to the heat carrier which is then transferred to a reactor where it is placed in contact with the combustible materials.
Abstract:
Methods and apparatuses are provided for pyrolysis using a falling bed reactor. The falling bed reactor may result in effective mixing between a heat carrier and biomass, and may reduce or eliminate inert gas requirements.
Abstract:
A dry distillation reactor for a raw material of hydrocarbon with a solid heat carrier is provided. An inner component with a pore path or a pore space is arranged inside the reactor to form a flow channel for the gas-phase product of the dry distillation. Also a dry distillation method using the dry distillation reactor is provided. The dry distillation method includes moving the reacting materials from top to bottom; moving a gas-phase product of the dry distillation along a designed path in the reactor; and finally leading same out through an outlet arranged in a central collecting channel for the gas-phase product of the dry distillation.
Abstract:
A fast pyrolysis heat exchanger system and method for economically and efficiently converting biomass and other combustible materials into bio-oil. The system employs multiple closed loop tubes situated inside the heat exchanger. As heat carrier is deposited at the top of the heat exchanger and caused to move downwardly therethrough, heat is transferred from the tubes to the heat carrier which is then transferred to a reactor where it is placed in contact with the combustible materials. Vapor containing char fines is discharged from the reactor into a vacuum-operated blow back filter. The blow back filter is activated when a drop in vacuum level at the output of the reactor is detected. Thereby, excess char buildup on the blow back filter elements is removed.

Abstract:
A dual bed pyrolysis system may include a falling bed reactor employing a heat carrier particulate to pyrolyze biomass to create a pyrolysis product and a pyrolysis waste product. The dual bed pyrolysis system may also include a fluidized bed reactor. The fluidized bed reactor may accept the pyrolysis waste product including char and heat carrier particulate from the falling bed reactor. The fluidized bed reactor may combust the char in the presence of the heat carrier particulate. The fluidized bed reactor may combust the char to reheat the heat carrier particulate. The reheated heat carrier particulate may be provided to the falling bed reactor to pyrolyze biomass to create a pyrolysis product and a pyrolysis waste product.
Abstract:
The present invention relates to a process and a system for generating energy from biomass/organic wastes. A process for generating a product gas from biomass comprises of pyrolyzing the biomass in a pyrolyzer by contacting the biomass with hot heat carriers to obtain pyrolysis gas and char; passing the pyrolysis gas to a reformer containing a reactant to obtain a product gas; and firing a part of the product gas coming out of the reformer back to the heater tubes of the reformer. Firing a part of the product gas through the fired heater tubes of the reformer provides the heat for sustaining the reaction between the pyrolysis gas and the reactant to form the product gas.
