Optimizing Hydrochars as a Hydrocarbon Remediation Amendment

零售燃料分配将柴油和汽油释放到土壤中，导致石油碳氢化合物(PHC)污染。在寒冷气候的土壤中，由于冻结和地质模拟，PHC的自然衰减是有限的。修复这些土壤的一种方法是通过添加微生物降解污染物所需的必要营养来刺激土壤微生物降解PHC。为改进碳氢化合物的原位生物修复，迫切需要在修复修正方面取得进展。氢化碳是一种富含碳的固体材料，它可能产生一种新的修复改良剂，可以从土壤溶液中吸附PHC，然后将其吸附在土壤表面，最终实现生物降解。目前，作为修复改良剂的氢化碳的合成和反应活性仍未得到测试。本CU-I2I提案的目标是：(A)优化含磷水合物的合成；(B)在实验室条件下评价其作为修复材料的性能。(C)在PHC污染场地进行现场规模的氢气试验；(D)为研究生和本科生建立独特的学院-大学培训方案。学生将与工业伙伴合作，并在进行积极现场修复的现场进行研究。将这些培训目标与我们的研究项目相结合，将满足行业对解释现场补救理论和应用的专业培训的需求。这项CU-I2I不仅将开发一种补救技术，还将为现场补救从业者开发一条独特的培训渠道。

Retail fuel distribution releases diesel and gasoline into soil, resulting in petroleum hydrocarbon (PHC)contamination. In cold climate soils, natural attenuation of PHC is limited due to freezing and geologicallimitations. One way to remediate these soils is to stimulate soil organisms to degrade PHC by adding thenecessary nutrients that microbes need to degrade the contaminants. Advances in remediation amendments areurgently needed to improve in-situ biological remediation of hydrocarbons. Hydrochars, a carbon-rich solidmaterial potentially produces a new kind of remediation amendment that can sorb PHC from the soil's solutionand then, as it in term sorbs onto the soil surface, traps it in place for eventual biological degradation.Currently, the synthesis and reactivity of hydrochars as remediation amendments remains untested.The objectives of this CU-I2I proposal are to (a) optimize the synthesis of phosphate-bearing hydrochars (b)evaluate their performance as a remediation material for PHC-contaminated soils in laboratory conditions, (c)conduct field-scale trials of hydrochars on a PHC contaminated site and (d) build a unique College-Universitytraining program for graduate students and College undergraduates.This proposal contains a novel approach that leverages college, university and industrial expertise to create aunique training experience. Students will work with industrial partners and conduct research at sitesundergoing active in-situ remediation. Combining these training goals with our research project will addressesthe industry's need for professional training that explains both the theory and application of in-situ remediation.This CU-I2I will develop not only a remediation technology, but also a unique training pipeline forpractitioners of in-situ remediation.
