摘要:
A catalytic cellulignin fuel obtained by a biomass pre-hydrolysis process and that is composed of cellulose and globulized lignin with a specific surface of about 1.5-2.5 m2/g. The cellulignin fuel may be ground down to particles smaller than 250 μm and has a combustion heat value that can reach up to 18-20 MJ/kg and an ignition time equal to or shorter than 20 ms (0.02 s).
摘要:
A process wherein biomass is compacted at 300 kg/m3 by a helical feeder, degassed, flooded, heated, stirred, and pre-hydrolyzed. The sugar being recovered at a first washing within the reactor with values higher than 90%. The control of the process enables one to produce cellulignin with a high specific surface, 2 m2/g (measured by BET), compared with the value of 0.4 m2/g of non-hydrolyzed biomass, maintain crystallinity of the cellulose fibers, aiming at grinding it into fine particles (f
摘要:
An apparatus for the processing of pre-hydrolysis of biomass, particularly a reactor of the failsafe type, either mobile or not, which may be manufactured of microbonded carbon steel and coated with special material (refractory metals, plastics, etc.). The insertion of vacuum between the shell of the reactor and its coating prevents its implosion and permits the detection of leakage with the helium gas. The resistance to corrosion of the refractory metals enables carrying out of pre-hydrolysis and mineral digestion.

“VIBRATING HEAT EXCHANGER EQUIPMENT FOR LOW TEMPERATURE CONVERSION FOR ORGANIC WASTE TREATMENT AND ORGANIC WASTE TREATMENT PROCESSING THROUGH THE USE OF VIBRATING HEAT EXCHANGER EQUIPMENT FOR LOW TEMPERATURE CONVERSION” The present invention relates to a reactor and the respective procedure that employs it, for processing lipid and protein rich organic waste using the technique of low temperature conversion, the reactor also being used for the treatment of waste with organochlorine contaminants and processing lignocellulosic organic waste, the main products being generated during the processing of oil and coal. The reactor (1) essentially consists of a single bypass tube shell-type heat exchanger, with several heating tubes (7) of cylindrical shape and is mounted so that the axis of the heating tubes (7) are positioned vertically with a triangular distribution, which facilitates the construction of devices with circular section and facilitates the distribution of the raw material. The reactor (1) has arrangements for continuous operation, due to a system which promotes the equipment (1) vibration (13), facilitating the loading of raw material and unloading of coal, as well as a condensing unit (27) of the vapors produced in the process, in order to obtain the fuel oil.
