The present invention is directed to an apparatus and method for controlling mass flow rate of a particulate solids and gas mixture to a reactor. In particular, the fast response of a mass flow rate-indicating device is combined with the longer term accuracies in changes in the total mass from weigh cells to yield rapid and more accurate loss-in-weight measurements than conventional systems.

Pressure compensated weigh system

The present invention is directed to an apparatus and method for minimizing mass flow rate fluctuations of a particulate solid fuel and gas mixture having a coal mass flow rate ranging from about 50-800 kg/m.sup.3 and a corresponding frequency range of about 0.1 to 100 Hertz transported to a reactor.

Feed line-pulsed gas injection

The present invention is directed to an apparatus and method for minimizing mass flow rate fluctuations of a particulate solid fuel and gas mixture having a coal mixture mass flow rate of about 50-800 kg/cubic meter and a corresponding frequency range of about 0.1 to 100 Hertz to a reactor.

Feed line design

A method and apparatus for controlling moisture content of a solid, such as pulverized coal, conveyed to a reactor, such as a gasifier, by controlling the temperature of a gas injected into a pulverizer or dryer based on the moisture content control of the coal transported to the gasifier.

Mill/dryer gas temperature control

3-Bromobenzaldehyde is prepared by treating benzaldehyde with bromine chloride in the presence of aluminum chloride and a solvent, under specified conditions.
