“…Molecules that may be present are eliminated because they cannot exist in this triple charged state. The further mass analysis in a magnetic field provides the concentration of 12 C, 13 C, and 14 C atoms in the analyzed samples [24][25][26][27]. The distribution of fossil carbon and biocarbon in the analyzed samples is then determined after checking that practically no more 14 C is present in the purely fossil reference samples compared with the ones originating from biomass.…”

An analytical platform was developed for the detection of biomass oxygenates and biocarbon in biogasoline produced by coprocessing of hydrodeoxygenated pyrolysis oils (HDO‐oil) and vacuum gas oil. A combination of different analytical techniques is necessary for analyzing such complex mixtures. The presence of various oxygenated compounds such as alcohols, acids, and phenols was quantified using phosphorus nuclear magnetic resonance spectroscopy. Different alkylphenols were identified using two‐dimensional gas chromatography‐mass spectrometry. The transformations of lignin oligomers present in HDO‐oil were determined with size‐exclusion chromatography carried out for the products. Accelerator mass spectrometry was used to make the distinction between carbonaceous material of biological origin and that of fossil origin. This type of analytical platform, which is tailored for bio‐oil identification and quantification, appears to be required for exploratory catalyst research and kinetic studies in this rapidly expanding domain. © 2011 American Institute of Chemical Engineers Environ Prog, 32: 377‐383, 2013

“…The pMC value of fossil-based carbon is 0%. The biobased carbon content for plastic products can be calculated by dividing the pMC value of the sample material by 1.04, on the basis of CEN/TS 16137, or by multiplying the pMC value by 0.95, on the basis of ASTM D6866-12 [14][15][16][17]. Some problems are associated with using the ISO 16620 series for rubber products.…”

Production of rubber products with biobased constituents from biomass resources is desirable for conserving our planet's limited resources and preventing global warming. Herein, a natural rubber model compound was produced to determine the biobased contents as per various indices for calculating the amount of biomass resources used in rubber products. The biobased mass and biobased carbon contents of the natural rubber model compound were 38.7% and 39.2%, respectively, which were calculated from the feed amounts of the constituents as per the International Organization for Standardization (ISO)/the draft of International Standard (DIS) 16620-2 and 16620-4. The model compound was separated into its constituents such as polymer, additive, carbon black, and zinc oxide using ISO 1407, 4650, 7720-2, and 9924-3. The biobased carbon content of this model compound was 37.6%, calculated from the percent of modern carbon (pMC), which was measured directly using accelerator mass spectrometry (AMS). The calculated values for this model compound agreed with those calculated from the feed amounts of the constituents. Thus, it was confirmed that these calculation and determination methods of the biobased mass and the biobased carbon contents for rubber products should be published as new ISO international standards after a discussion at technical committee 45, "rubber and rubber products" to evaluate rubber products with larger biobased contents of natural rubber and other biobased ingredients.
