A process for producing kerosene involves reacting a renewable feedstock in a hydrotreating stage under hydrotreating conditions sufficient to cause a hydrotreating reaction to produce a hydrotreated effluent. The hydrotreated effluent is separated to produce a hydrotreated liquid stream and a separation system off-gas stream. The hydrotreated liquid stream is directed to a post-treatment section where the gas is stripped to produce a stripped liquid product stream and a stripper off-gas stream. A gas stream comprising the separation system off-gas stream and/or the stripper off-gas stream is directed to a gas treatment section to obtain a pressurized gas stream and a hydrocarbon fraction that is liquid at a pressure in the range of 0 MPaG to 1.5 MPaG and a temperature in the range of 0 DEG C to 50 DEG C. The hydrocarbon fraction is recycled to the aftertreatment section. The kerosene stream separated in the product recovery unit has a higher yield compared to conventional processes. 一种用于生产煤油的方法，该方法涉及使可再生原料在氢
