Pitaya is rich in nutrition and unique in function and contains vegetable albumin, anthocyanins, rich vitamins, and water soluble dietary fiber, which are rare in fruits and vegetables. However, researches mostly focused on pitaya cultivation, biological characteristics, fresh‐keeping, and lacked analyses about chemical composition of pitaya. Therefore, ethanol extraction and GC/MS were used to extract and identify the bioactive components in pulp and pericarp of red pitaya and white pitaya. The extracting results showed that percentages of ethanol extracts from pulp and pericarp of red pitaya were 14.5% and 12%, whereas those of white pitaya were 16% and 12%. The GC/MS results showed that different kinds of bioactive constituents were identified in fresh pericarp and pulp of red pitaya and white pitaya. In the four ethanol extracts, there are rich polysiloxane plant organosilicon with total contents of 10.09%, 24.21%, 25.77%, and 23.25%. Meanwhile, there are many heterocyclic substances, and the content of pericarp is much higher than that of pulp. The four ethanol extracts also contain some other bioactive ingredients, such as esters, hydrocarbons, alcohols, amides, halides, and fatty acids, which can be used as raw materials for biomedicine, advanced cosmetics, and skin care products.

Because most compounds are easy to be decomposed into smaller compounds, they are extracted at the beginning of the chromatogram at a lower retention time.…”

The production of energy from wood biomass is as old as humanity itself. There has been enormous progress in research of sustainable pyrolysis processes for optimal energy conversion in the past 30 years. Pyrolisis–gas chromatography–mass spectrometry (PY‐GC‐MS) was used to examine the components of bark and wood of Toona sinensis for expanding high value utilization different parts of trees. In the study, 174 chemical constituents were identified in the bark; 169 chemical constituents were identified in the wood, respectively. The chemical composition of bark is different from that of wood. The change in thermal cracking 30 min ago is not very large. In the retention time is more than 30 min, they are very different. Because the ash content of bark had much large corresponding wood. Mainly the phenols and their derivatives formed after the pyrolysis of lignin and extractives. The chemical composition of T. sinensis provides a scientific basis for the development and utilization of the plant. The richer chemical constituents of T. sinensis are found, which will provide new scientific evidence for further development and utilization of bark and wood of T. sinensis.

“…The use of biomass-derived fuel in fuel cell vehicles can achieve green transportation with minimal pollutant emission. When biomass-derived fuel is used in a proton exchange membrane (PEM) fuel cell, the syngas production [5], steam reforming, and water gas shift reactions are most necessary to provide pure hydrogen. Although a recent study showed that it is possible to directly use biomass in a fuel cell without converting biomass into hydrogen rich gases [6], the power density is too low for practical applications.…”

External chemical reactors for steam reforming and water gas shift reactions are needed for a proton exchange membrane (PEM) fuel cell system using syngas fuel. For the preheating of syngas and stable steam reforming reaction at 600 °C, residual hydrogen from a fuel cell and a certain amount of additional syngas are burned. The combustion temperature is calculated and the molar ratio of the syngas into burner and steam reformer is determined. Based on thermodynamics and electrochemistry, the electric power density and energy conversion efficiency of a PEM fuel cell based syngas are expressed. The effects of the temperature, the hydrogen utilization factor at the anode, and the molar ratio of the syngas into burner and steam reformer on the performance of a PEM fuel cell are discussed. To achieve the maximum power density or efficiency, the key parameters are determined. This manuscript presents the detailed operating process of a PEM fuel cell, the allocation of the syngas for combustion and electric generation, and the feasibility of a PEM fuel cell using syngas.
