Abstract

Aimed at multilayer composite reservoir with the double porosity, meanwhile considering the influence of well bore storage and skin effect, the seepage model for multilayer composite reservoir with the double porosity which the flow was steady from pore to crack was established in different outer boundary (infinite; closed; constant pressure) conditions; the exact solution of reservoir pressure drop and bottom hole pressure drop were obtained by Laplace transform in the Laplace space; the unified expression of solution was obtained by constructing similar kernel functions in different outer boundary conditions, therefore new method which solving this class of reservoir model is put forward, namely similar construction method. This method plays an important guiding role in exploring seepage law of oil and gas reservoir.

Abstract

Short energy intensive hydrothermal liquefaction (HTL) of biomass in the presence of Ni salt catalyst selectively generates H2 in the product gas and biocrude mainly containing C1-C3 acids (formic, lactic, propionic, acetic), HMF and furfural. The H2 mass balance indicated that only 3.12 vol% H2 in biomass (cotton) was released as product gas; 48.7 vol% was captured in the C1-C3 acids while the remainder H2 was trapped in oxygenated compounds and char. Continuing HTL after 120 minutes caused no further increase in gas phase H2 yields. To enhance the H2 yields with minimal energy input, solar photocatalytic reforming (PR) of the biocrude with Pt/TiO2 catalyst was investigated. Photocatalysis of activated carbon (AC) treated biocrude generated an additional H2, 17.82 wt%. H2 yields from photoreforming of simulated biocrude acid mixture and actual biocrude were compared. Enhanced H2 generation was observed with integrated HTL-PR of biomass.
