FUEL REFORMING SYSTEMS
Fuel reformation is a thermochemical process in which a fuel is converted into a hydrogen-rich stream.
Depending on the process conditions (such as temperature, pressure and stoichiometry of the reactants), the production of hydrogen, carbon monoxide or specific ratios of these gases (called synthesis gas) can be achieved.
Conventionally, natural gas, LPG (Liquefied Petroleum Gas), biogas or, pioneering in Brazil, through a proprietary technology developed by Hytron, ethanol.
Reforming systems may be composed with suitable post-treatment and gas purification in order to achieve any required specification.
The process may further be adapted to alternative fuels, including glycerol, vegetable oils, oily residues, among others, as available in each application.
Water electrolysis is understood as the electrochemical process of water dissociation into its components, hydrogen and oxygen.
Modern electrolyzers are classified according to their type of electrolyte (ionic conducting medium presented between electrodes, cathode and anode). More common technologies are:
Alkaline, in which the electrolyte corresponds to an aqueous solution of KOH (Potassium Hydroxide) and;
PEM, where the electrolyte corresponds to a solid ionic conductor, usually in the form of a polymeric membrane.
This process can be exploited for the production of hydrogen or for the production of hydrogen and oxygen, separately, in systems with a wide range of capacities. Electrolyzers have typical turn-down ratio to 20% and can provide gases directly at pressures up to 30 barg, avoiding intermediate mechanical compressors.

GAS PURIFICATION SYSTEMS
Purification of gas streams (up to 99.9999% +) demands attention to its origin and application. The choice of the purification technology must be made respecting reliability and feasibility criteria.
Among available solutions, PSA (Pressure Swing Adsorption) systems stand out. In this technology the adsorbent beds are filled with specially chosen materials, considering each application. These materials are responsible for the removal of impurities from the incoming stream, providing only the desired gaseous component at the outlet.
These systems are designed for uninterrupted supply of its product, which is achieved through the integration of multiple purification beds. This arrangement guarantees automatic regeneration of the columns and the autonomous operation of the process, with potential for additional use of the residual gas stream.
This technology is applicable to the purification of hydrogen, methane, carbon monoxide, helium, nitrogen, oxygen, among other gases.
PSA systems have capacities up to thousands of Nm3/h, typical modularization of production between 40 and 100% and can provide the purified gases with low pressure drop.
Regardless your process condition, Hytron technical team will be able to fulfill your expectations. Contact us for more details.
HYDROGEN REFUELING STATIONS (HRS)
Hydrogen Refueling Stations (HRS) are used to supply hydrogen for fuel cell electric vehicles (light vehicles, buses, forklifts, etc).
HRS are autonomous systems for ultrapure hydrogen production, supplied with a supervisory software and capable of meeting the most stringent fuel quality standards (including SAE J2719).
The stations are composed by the equipment responsible for the production, purification, compression, storage and dispensing of hydrogen. Using reforming or water electrolysis technologies, Hytron is able to offer turn-key HRS.
Hytron’s team participated in VEGA II Project (coordinated by UNICAMP's Hydrogen Laboratory), which conceived the first hydrogen-powered vehicle in the Southern Hemisphere (2004).
Pyrolysis is a thermal decomposition process of organic substances, in an environment with very little, if any, oxygen.
This technology enables the use of municipal solid wastes (MSW), solid wastes from processes, agricultural residues, among others, as options for the production of industrial gases or power generation.
Among distinct technologies, Rotating Drum Slow Pyrolysis dispenses the usual preliminary raw material drying, since it is able to handle inputs with about 30% moist. The gaseous products consist in a mixture of high calorific, rich hydrogen and carbon monoxide stream.
The technology also presents as a product a solid compound called biochar. This product can be used directly in solid fuel burners or as a complement to soils.
This technology is a feasible option to incineration systems, with processing capacities between 2 and 135 TPD (tonnes per day) and equivalent stationary power generation between 60 kWe and 2.7 MWe, in addition to expressive cogeneration potential.
The consultancy is carried out evaluating, among other aspects, current demand and supplying models (on-site generation, liquid or gas bulk supply, etc.), seeking operational reliability and comparing the model undergoing with the best solution designed.
The expertise of the Hytron team in the on-site generation of industrial and ultrapure gases allows them to offer innovative projects in control and supervision of industrial processes, whether in new or pre-existing applications.
Our focus is on increasing the profitability and efficiency of your processes.
The consultancy provide focus on two main areas:
Analysis for consumers of so-called Air Gases and Special Gases;
Engineering, Procurement, Construction and Management for the implantation of new projects or retrofit.
Hytron’s team advises companies that consume gases (including oxygen, nitrogen, hydrogen, argon, laboratory gases, among others) aiming for maximum efficiency in their consumption.
