| Introduction
Hydrogen generation by methanol decomposition was developed in the last two decades. This technology by Angstrom Advanced features low cost, simple user friendly operation and very easy maintenance. The methanol and water is mixed in specified ratio and pressurized. This mixture passes through evaporator, metering pump and then to super heater. The hot gas is then fed into a reactor. The reaction of methanol reforming and the shift reaction, takes place in the catalytic reactor of fixed beds simultaneously to form H2 and CO2 finally. The mixed gas after reaction is passed though the heat exchanger to have the heat exchanged with feed gas in order to recover part of heat and then fed further into the gas-liquid separation buffer to separate the unreacted methanol and water, prior to passing to the condenser and cooling gas dryer for condensation in order to ensure the methanol in the reforming gas to meet the specified quality. The liquid from condensation and separation is the mixture of methanol and water, which are returned back to the feedstock tank for reuse. The reformed gas enters a set of PSA systems, which separates all impurities through the adsorption and separation in one time. The hydrogen purification through PSA is adopted in the manner of 4-1-2/P and desorption at the atmospheric pressure (4 absorbers, one absorber is in adsorption, 2 times of pressure equalization). Each adsorber in a cycle undergoes adsorption (A); equalized pressure-drop for the first time (E1D); equalized pressure-drop for the second time (E2D); cis-exhale (PP), inverse purge (D); flushing (P); equalized pressure increase for the second time (E2R); equalized pressure increase for the first time (E1R) and the final pressurisation (FR). The four adsorbers shift regularly, alternating between adsorption and regeneration, according to the arranged program in a closed loop. In this way raw gas feeds and hydrogen withdraws continuously. There are a small amount of carbon monoxide and about 35%(v/v) hydrogen in the desorbed off gas. If it is recovered and used as fuel, it brings the benefit of saving energy and minimizing the pollution.

Angstrom Advanced – A Profitable, Clean Tech Solution to Grid Congestion in China
Boston, MA United States
Angstrom Advanced Inc has paid a lot of attention to what is going on in China, especially the renewable energy section. The leading magazine “Energy Digital” recently published an article from Verde about this market opportunity:
“As China’s economy rapidly grows, the energy sector faces two major challenges: an imbalance of supply and demand and a lack of distribution and transmission infrastructure.
As by far the largest wind power market in the world (with 63 GW installed capacity), China gets more than 30% of its wind market’s revenue from federal subsidies—an exceptional amount of support from the government that has adversely caused a massive oversupply issue. In 2011, abandoned wind power amounted to over 10 billion KWh, exceeding 50 percent of the industry’s profit. Much of that energy was wasted, mostly positioned near farms lacking sufficient distribution/transmission infrastructure capable of moving excess energy to areas of higher demand. Our instruments and plants have been delivered to many renowned organizations.

Distributed Energy Article about Angstrom Advanced Inc
Feb 25th 2013 Boston, United States
The leading clean energy magazine “Distributed Energy” has recently published an article about the cutting-edge technology Angstrom Advanced has developed to specially serve the Distributed Renewable Energy market: “Hydrogen is a very valuable alternative to fossil fuel for distributed energy generation, delivering a high-powered solution with minimal environmental and safety concerns. Green businesses, telecomm providers, governments, and renewable energy advocates can now produce on-demand energy for their assets, at minimal cost and using commercially available equipment. This article will look at the benefits associated with hydrogen and fuel cell energy systems compared to fossil fuel and chemical alternatives as well as the inherent costs associated with a fuel cell on-demand generator. This analysis will show that it is not only technically feasible to use hydrogen for on-demand energy in certain, but also that it can be more economic than the alternatives. Diesel generators are valuable when used only for applications that have short run times (less than eight hours per day) and where they are in proximity to a low-cost fuel source. For longer run times, and when used in more remote and extreme conditions, renewable hydrogen generators are an ideal solution for providing on-demand energy.

Gas World Article about Angstrom Advanced Inc
Feb 25th 2013 Boston, United States
The leading Magazine in Biomass field, Gas World, published an article about the Hydrogen Reformer technology of Angstrom Advanced Inc. This is another recognition of Angstrom’s cutting edge technical innovation and its fast expanding fame in the industry: “Here and now gasification plants have the functionality to make the hydrogen economy a real possibility. Greatly reducing the cost of hydrogen production by using renewable resources and advanced, reliable processing techniques enables a gasification plant to produce valuable hydrogen product from waste materials. While the technology is available to enable this functionality, however, most plants opt to simply create SynGas (a mixture of hydrogen and carbon monoxide.) However, as market demand for hydrogen increases in parallel with the stationary and transportation fuel cell industry, gasification facilities will likely be the top producer of renewable hydrogen fuel – mostly due to the low cost of production and the scalability of plants. This paper will discuss minor changes to gasification plants that plant operators can implement which will maximize the value of their assets, and enable them to easily create a product with higher purity and productivity.

| Prior to pressurization, desulfurization, and mixing with aqueous vapor, natural gas is passed through a special reformer which is packed with a catalyst for cracking and reforming the effluent mixture of hydrogen, carbon dioxide and carbon monoxide. After part of the heat is recovered, hydrogen will be obtained by removing excess carbon monoxide from the reformed effluent. The shift gas is then purified further through pressure swing adsorption (PSA), to obtain pure hydrogen.

Introduction: |
||||||||||||
| Pressure Swing Adsorption (PSA) by Angstrom Advanced is used to separate hydrogen gas from other gases by feeding the gas under a certain pressure. This separation process occurs in an adsorption tower and is advantageous in its low cost, low capacity, minimal maintenance requirements and user-friendly interface. The H2 Purifying System removes oxygen from hydrogen via a catalyst to obtain high purity H2 after adsorption and drying through the dust filter. The system can remove oxygen down to levels of 1ppm. Through one step of purification, the purity of the hydrogen generated can reach between 99.999~99.9999% and the dew point can be lower than -70°C; Through a second purification step, impurities can be lowered down to less than 0.1ppm and dew point can be lowered to -90°C.Our instruments and plants have been delivered to many renowned organizations.

| Introduction:
In this setup by Angstrom Advanced, compressed air is pumped through a compressor filter, along with polymer membrane filters. Due to variable solubility and proliferation factors, different gasses in the air penetrate the membrane at different rates, allowing for their separation. Based on their diffusion rates, the gasses in the air are then placed into one of two categories: “rapid gas” or “slow gas.” After being compacted and purified (to remove oil, water, and dust), the air will be passed through the membrane in order to create a separation of the gasses. The “rapid gasses,” oxygen, carbon dioxide, and some vapors, will be the first to infiltrate the membrane wall, and exit through a discharge port via air pressure. Because nitrogen is characterized as a “slow gas,” it will flow from the gas collector at the end of the pressure box, and finally enter a buffer tank where it will be stored. |
