A continuous acoustic chemical microreactor system is disclosed. The system includes a continuous process vessel (CPV) and an acoustic agitator coupled to the CPV and configured to agitate the CPV along an oscillation axis. The CPV includes a reactant inlet configured to receive one or more reactants into the CPV, an elongated tube coupled at a first end to the reactant inlet and configured to receive the reactants from the reactant inlet, and a product outlet coupled to a second end of the elongated tube and configured to discharge a product of a chemical reaction among the reactants from the CPV. The acoustic agitator is configured to agitate the CPV along the oscillation axis such that the inner surface of the elongated tube accelerates the one or more reactants in alternating upward and downward directions along the oscillation axis.

An autothermal process of concentric bubbling fluid double bed for the production of syngas by gasification with biomass steam, in the presence of a granular material includes: continuous gasification under stationary bed condition of said granular material in bubbling fluidisation regime of biomass with water vapour with thermochemical transformation of the fuel into raw syngas and char, the raw syngas including heavy hydrocarbons in the steam state and any harmful compounds in traces, in a first reaction volume; combustion in bubbling fluidised bed with air of the char and of auxiliary fuel in a second reaction volume; the transfer velocity of the granular material between the first and second reaction volumes being such that the thermal difference does not exceed 20 C.; separation from the raw syngas by hot filters; and elimination of any harmful compounds in traces.

Electrically heated reforming reactors and associated reforming processes are disclosed, which benefit from a number of advantages in terms of attaining and controlling the input of heat to catalytic conversion processes such as in the reforming of hydrocarbons (e.g., methane) using H.sub.2O and/or CO.sub.2 as an oxidant. The disclosed reactors provide the ability to target the input of heat to specific regions within a catalyst bed volume. This allows for the control of the temperature profile in one or more dimensions (e.g., axially and/or radially) and/or otherwise tailoring heat input for processing specific reformer feeds, achieving specific reformer products, effectively utilizing the catalyst, and/or compensating for a number of operating parameters (e.g., flow distribution). Dynamic control of the heat input may be used in response to changes in feed or product composition and/or catalyst activity.
